- an identifiable insult such as surgery or other trauma
- a disease e.g., kidney stones, mechanical low back pain, etc.
- public health statistics several hundred million people worldwide undergo inpatient or outpatient surgery each year.
- several hundred million visits are made annually to the emergency room.
- emergency room visits it is estimated by survey data that more than 20% require analgesic treatment.
- Recent studies have shown that more than 60% of patients who undergo surgery experience moderate to severe pain despite analgesic treatment.

- parenteral drug formulations have become a very important component in the arsenal of available drug delivery options, particularly for drugs having analgesic, antiinflammatory or antipyretic effects.
- Parenteral routes of administration including subcutaneous, intramuscular, intrathecal, epidural and intravenous injection, offer numerous benefits over oral delivery in particular situations, for a wide variety of drugs.
- parenteral administration of a drug typically results in attainment of a therapeutically effective blood concentration of the drug in a shorter time than is achievable by oral administration. This is especially true of intravenous injection, whereby the drug is placed directly into the bloodstream.
- Parenteral administration can also result in more predictable blood serum concentrations of a drug, because drug loss in the gastrointestinal tract due to absorption, distribution, metabolism, binding to food and other causes are eliminated.
- Parenteral administration is generally the preferred method of drug delivery in emergency situations, and is also useful in treating subjects who are uncooperative, unconscious, or otherwise unable or unwilling to accept oral medication.
- Parenteral drugs are particularly useful for treating a condition such as pain, inflammation or fever when: 1 ) the condition is of severe intensity; 2) there is a need for rapid onset of effect; 3) there is a need for rapid or frequent dose titration to keep condition under control; and/or 4) the patient is unable to receive oral medication e.g., due to nausea, vomiting, confusion, obtundation, loss of consciousness and bowel obstruction.
- opioids exert an analgesic effect is through agonism at the various opioid receptors, e.g., mu, delta and/or kappa.
- the opioids are well-known for their potential for physical dependence and addiction.
- Other side effects of opioids, particularly in the acute setting and more particularly in non-opioid tolerant or opioid naive patients, include nausea, vomiting, pruritus, constipation, sedation, and potentially fatal respiratory depression.
- opioids particularly in the acute setting and more particularly in non-opioid tolerant or opioid naive patients, include nausea, vomiting, pruritus, constipation, sedation, and potentially fatal respiratory depression.
- increased doses are required to achieve a satisfactory analgesic effect.
- alternative therapies for the management of acute pain are widely sought, so as to minimize the amount of opioid patients will require for pain management.
- Compounds which serve as replacements for opioids or reduce the required opioid dose have utility in the treatment of pain.
- the NSAIDs are highly effective as analgesics. They are used to treat both acute and chronic pain, usually by the oral route of administration.
- the main mechanism by which NSAIDs exert an analgesic effect is through the inhibition of the synthesis of certain prostaglandin, or prostanoids.
- the synthesis of prostanoids utilizes two distinct COX enzymes: COX-I and COX-2.
- Traditional NSAIDs inhibit both enzymes.
- NSAIDs may also inhibit other lipogenic enzymes, such as 5-lipooxygenase.
- NSAIDs are not addictive, they are not without significant toxic effects, such as gastrointestinal injury, hepatotoxicity and decrease clotting ability.
- Ketorolac is presently the only NSAID available in parenteral form in the United
- ketorolac has been withdrawn from the market by the local health authorities, due to its high propensity to cause serious and life threatening side effects. Injectable ketorolac must be given every 4 to 6 hours to provide continuous relief of pain. In some countries, other parenteral NSAIDs such as diclofenac and lornoxicam are also available, but in most countries, ketorolac still remains by far the most frequently used injectable NSAID.
- Parecoxib a parenteral COX-2 selective NSAID, has been approved in Europe with restrictions on its use and has been twice denied approval by the United States Food and Drug Administration for the management of acute post-surgical pain.
- parecoxib the injectable prodrug of the now withdrawn drug, valdecoxib
- An important early adverse postsurgical safety signal came from a CABG study included in the original U.S. NDA. In the parecoxib and valdecoxib group, 19.0% had serious adverse events, versus 9.9% in the placebo group.
- NSAIDs When administered by the IV route, many NSAIDs are associated with one or more drawbacks, including poor solubility, pain on injection, venous irritation, thrombophlebitis, intramuscular pain and irritation, and the need to inject in a large volume of physiologic fluid and/or as a slow IV infusion (instead of as a bolus) to minimize local irritation.
- drawbacks including poor solubility, pain on injection, venous irritation, thrombophlebitis, intramuscular pain and irritation.
- Kostamovaara et al. (Br. J. Anaesth.
- Benzyl alcohol has been associated with a fatal toxic syndrome in premature infants, and parenteral preparations containing the benzyl alcohol are not recommended in neonates. ⁇ See British National Formulary, No. 49, March 2005).
- the 3 mL volume for IM administration is more that the 2 mL maximum recommended volume and therefore it may be associated with increased frequency and intensity of injection site pain.
- Some regulatory health authorities have required the following dosing language for IM diclofenac acid (Voltarol Ampoules. U.K. Summary of Product Characteristics, March 2005):
- Diclofenac must not be given as an intravenous bolus injection. Diclofenac must be diluted with 100-500 mL of either sodium chloride solution (0.9%) or glucose solution (5%). Both solutions should be buffered with sodium bicarbonate solution (0.5 mL 8.4% or 1 mL 4.2%). Only clear solutions should be used. Two alternative regimens are recommended: For the treatment of moderate to severe post-operative pain, 75 mg should be infused continuously over a period of 30 minutes to 2 hours. If necessary, treatment may be repeated after 4-6 hours, not exceeding 150 mg within any period of 24 hours. For the prevention of post-operative pain, a loading dose of 25 to 50 mg should be infused after surgery over 15 minutes to 1 hour, followed by a continuous infusion of approximately 5 mg per hour up to a maximum daily dosage of 150 mg.”
- Pain as a consequence of administration of a drug intended to ameliorate other pains can lead to patient refusal to accept therapy and require diagnostic workup to rule out infiltration, extravasation and infection at the injection site. It can also lead to further medical complications, increased reliance on opioid analgesics for pain relief, delayed discharge from hospital and increased cost of therapy. Patients report the pain sensation as stinging, burning, soreness, tenderness, aching, throbbing, cramping, gripping and radiating. It may be localized to the injection site or it may radiate to the proximal area, e.g., the arm. It may or may not be accompanied by redness.
- Phlebitis is an inflammation of the vein in which endothelial cells of the venous wall become irritated and cells roughen, allowing the adherence of platelets.
- the site is tender to touch and can be very painful. Phlebitis can prolong hospitalization unless it is treated early.
- the process of phlebitis formation involves increased capillary permeability, resulting in leakage of proteins and fluids into interstitial space.
- the traumatized tissue continues to be irritated chemically. This in turn provokes an immune reaction, resulting in mobilization of leukocytes release of inflammatory mediators [Phillips, LD, Manual of I.V. Therapeutics, 3 rd Edition (2001), p.

- Phlebitis occurs when a vein becomes inflamed by irritation or vesicant solutions or drugs. Although the use of a 0.5 to 1.0 micron inline filter can remove particulate matter not visible to the naked eye, it cannot eliminate the precipitation that occurs when the drug comes in contact with blood. Precipitation is considered to be a major cause of injection site pain, venous irritation and phlebitis.
- Solvents, acids and bases, and some drugs can damage living tissue.
- some dissolved drugs can produce undesirable pharmacological effects by reacting with specific receptors on the vein walls.
- the undesirable effects caused pharmacologically and chemically are worsened by direct cellular contact with the highly concentrated precipitate.
- precipitation of the drug within the vein upon dilution significantly exacerbates the irritation and is a key factor in determining the duration and severity of the irritation.
- One approach to reducing mechanical, chemical and idiopathic IV NSAID irritation is to drastically reduce the dose of NSAID administered to the patient, while still providing an effective analgesic, anti-inflammatory and/or antipyretic effect.
- One approach to reducing pain, irritation and muscular or subcutaneous toxicity after IM or SC (SQ) administration is to drastically reduce the dose of NSAID administered to the patient, while still providing an effective analgesic, anti-inflammatory and/or antipyretic effect.
- One approach to reducing pain, irritation and muscular or subcutaneous toxicity after IM or SC (SQ) administration is to drastically reduce the volume of NSAID administered to the patient, while still providing an effective analgesic, anti-inflammatory and/or antipyretic effect.
- One approach to reducing and irritation, epidural hematoma, abscess, inflammatory lesions and granulomas after epidural or intrathecal administration is to drastically reduce the dose of NSAID administered to the patient, while still providing an effective analgesic or anti-inflammatory effect.
- NSAIDS, epidural and intrathecal administration are contraindicated.
- the volume is commensurately reduced, thereby providing the option of epidural and intrathecal NSAID administration.
- One approach to improving the tolerability of NSAIDS after parenteral administration is to drastically reduce the dose of NSAID administered to the patient, thereby reducing the need for irritating and otherwise toxic or disagreeable pharmaceutical excipients such as benzyl alcohol.
- the parenteral route of NSAID administration is usually used in the post-surgical pain, post-traumatic pain or intensive or critical care setting, where the patient is particularly predisposed metabolic stress, gastrointestinal perforation, ulcers and bleeding, and bleeding from the site of surgery or trauma.
- These adverse effects, along with the aforementioned injection site effects are particularly important with the use of parenteral NSAIDS. Most of the adverse effects of NSAIDS are dose related. Consequently the lowest possible dose of an NSAID associated therapeutic effectiveness is usually suggested.
- NSAID side effects can occur in all patients, some patient groups are at particular risk.
- Patients are particular risk include those who: (i) are elderly; (ii) are cachectic' (iii) are immunocompromised; (iv) have a malignancy; (iv) are receiving corticosteroids; (v) with a history of significant alcohol consumption; (vi) are smokers; (vii) are receiving long-term NSAID therapy; (viii) are receiving high doses of NSAID's; (ix) have prior history of peptic ulcer disease, perforations and GI bleeding; (x) have ischemic heart disease; (xi) are undergoing CABD surgery; (xii) have a history of stroke; (xiii) are anticoagulated; (xiv) have a history of renal impairment and renovascular disease; (xv) have hepatic impairment; and (xvi) have a history of hypertension. Additional information on risk factors for NSAID toxicity may be found in the scientific and
- NSAIDs for parenteral administration (e.g., intravenous [IM], intramuscular [IM], subcutaneous [SC], intrathecal [IT], epidural], particularly IV administration, there is a need for new therapeutic methods and pharmaceutical compositions that have analgesic, anti-inflammatory and antipyretic activity.
- parenteral administration e.g., intravenous [IM], intramuscular [IM], subcutaneous [SC], intrathecal [IT], epidural]
- analgesic, anti-inflammatory and antipyretic methods and pharmaceutical compositions that are: (i) readily soluble; (ii) have a reduced injection volume; (iii) have a rapid onset of effect; (iv) have a robust peak effect; (v) have a long duration of action; (vi) have a reduced incidence and severity of injection site pain, venous irritation and phlebitis; (vii) have a reduced propensity for gastrointestinal side effects, including dyspepsia, ulceration, perforation and bleeding; (viii) have a reduced frequency and severity of bleeding from or near the site of surgery or trauma; (ix) have a reduced frequency and severity of cardiovascular side effects; (x) have a reduced frequency and severity of injection site pain and irritation, epidural hematoma, abscess, inflammatory lesions and granulomas after epidural or intrathecal administration; and (xi) have a reduced frequency and severity of other NSAID side effects.
- An ideal parenteral NSAID formulation should provide robust analgesic, antiinflammatory, and antipyretic effects (rapid onset and high efficacy), as well as good tolerability at and around the injection site. Further, an ideal parenteral NSAID formulation should be safe for administration by the IM, IV, SC, IT and epidural routes. Additionally, an ideal parenteral NSAID formulation should be safe for administration by the IM, IV, SC, IT and epidural routes by avoiding the use of large quantities of potentially toxic solubilizing agents, e.g., benzyl alcohol and by avoiding or minimizing the risk of precipitation following injection.
- potentially toxic solubilizing agents e.g., benzyl alcohol
- One approach of the invention to encourage clinicians to liberally utilize parenteral NSAIDs and optimize pain control, especially in the setting of acute pain is to reduce the frequency and severity of NSAID associated side effects while providing an effective therapeutic intervention.
- acute pain e.g., acute postsurgical pain, trauma, renal colic, burn pain, etc
- clinicians are forced either manage pain, inflammation and fever sub- optimally or provide adequate analgesia while risking patient safety.
- One approach of the invention to reducing the various know toxicities of parenteral NSAID therapy while providing robust analgesic, anti-inflammatory and antipyretic is to utilize ultra-low doses of parenteral NSAID 's not previously described in the art, while still providing therapeutically effective analgesic, anti-inflammatory and antipyretic effects.
- ultra-low dose parenteral NSAIDS can reduce the know toxicities of parenteral NSAIDS though a significant reduction in the single, individual or unit dose of the administered NSAID and the total daily administered dose of the NSAID, each individual dose provides a shorter duration of action. This in turn requires a more frequent dosing and adversely impacts on: (i) nursing, pharmacy and other institutional resources; (ii) the cost of drug and supplies (syringes, alcohol swabs, sterile solution, infusion devices, etc); (iii) sterility and the risk of infection.
- One approach of the invention to mitigate against the adverse consequences of increased dosing frequency is to administer the ultra-low doses of parenteral NSAID using patient controlled analgesia (e.g., patient controlled intravenous analgesia [PCA] or patient controlled epidural analgesia [PCEA], or patient controlled analgesia using the intrathecal or subcutaneous route of administration).
- patient controlled analgesia e.g., patient controlled intravenous analgesia [PCA] or patient controlled epidural analgesia [PCEA], or patient controlled analgesia using the intrathecal or subcutaneous route of administration.
- Current standard of care does not recommend administration of NSAIDS by patient controlled analgesia.
- the standard of care recommends against administration of NSAIDS by patient controlled analgesia and for a majority of NSAIDS of the invention, there are no recommendations or working examples of NSAID administration by patient controlled analgesia.
- the present invention stems, in part from the surprising discovery that usual recommended doses of parenteral NSAIDS, with their associated adverse safety profile are not required to provide effective analgesic, anti-inflammatory and antipyretic effects. Such effects may be achieved with ultra-low dose NSAIDS, which have a reduced propensity for the known side effects of NSAIDS.
- the present invention stems, in part from the surprising discovery that usual recommended doses of parenteral NSAIDS given by IV infusion (e.g., over 5, 10, 15, 20 or 30 minutes), with their associated adverse safety profile are not required to provide effective analgesic, anti-inflammatory and antipyretic effects. Said effects may be achieved with ultra-low dose NSAIDS given by IV bolus, which have a reduced propensity for the known side effects of NSAIDS.
- ultra-low dose NSAIDS can provide robust analgesic, anti-inflammatory and antipyretic effects, with reduced NSAID toxicity and without the inconvenience associated with frequent administration.
- the ultra-low dose NSAID is preceded by one or more loading doses of the same NSAID by he same route of administration, said loading dose at least equal to the minimum approved or recommended dose of said NSAID by said route.
- the present invention involves the use of ultra-low dose
- the present invention involves the use of ULD of parenteral NSAIDs to provide effective anti-inflammatory effects.
- the present invention involves the use of ULD of parenteral NSAIDs to provide effective antipyretic effects.

- Nonsteroidal anti-inflammatory drugs typically have analgesic, anti-inflammatory, and antipyretic properties. Their mode of action appears to involve inhibition of cyclooxygenases (COX-2 and/or COX-I), leukotriene biosynthesis, and antibradykinin activity.
- COX-2 and/or COX-I cyclooxygenases
- NSAIDs may be non-selective (inhibit COX-I and COX-2 isozymes) or COX-2 selective (preferentially inhibit the COX-2 isozymes). NSAIDs can produce a wide variety of adverse effects.
- NSAID For each selected NSAID, standard of care, randomized clinical trials, evidence based medicine, anecdotal evidence, medical practice, tradition guide the selection of the range of doses utilized for the analgesic, anti-inflammatory and antipyretic effects in order to provide analgesia with the fewest possible side effects. Most NSAID analgesic use is by the oral route and for a majority of NSAIDs there are no data on efficacy or safety on their use by the parenteral route of administration. Although the exact mechanisms of adverse effects have not been clearly established, at least some appear related to COX-I inhibition, while at least some of the cardiovascular complications appear to be related to COX-2 inhibition. In addition to their gastrointestinal adverse effects, NSAIDs produce dose related inhibition of platelet aggregation, prolongation of bleeding time, renal impairment, and hepatotoxicity. Parenteral administration can produce injection site burning and pain.

- Ketoprofen ( ⁇ )-2-(3-benzoylphenyl)propionic acid) or (R,5>2-(3-benzoylphenyl) propionic acid), is a NSAID with analgesic, anti-inflammatory and antipyretic properties. These properties of ketoprofen have been demonstrated in classical animal models and in vitro test systems. Its mode of action appears to be similar to that of other NSAIDs and includes inhibition of prostaglandin (COX-I and COX-2 inhibition) and leukotriene biosynthesis, antibradykinin activity, and lysosome membrane-stabilizing activity. Chemically, ketoprofen belongs to the group of substituted 2-phenylpropionic acids.
- Ketoprofen as a racemate, or as the analgesically active enantiomer (+)-(S)-2-
- ketoprofen (3-benzoylphenyl)propionic acid (dexketoprofen), is marketed in a number of countries in a variety of forms, including oral solids, suppositories, and a topical gel.
- Ketoprofen is soluble in benzene, ethanol, chloroform, acetone, ether, and alkaline solutions, but it is practically insoluble in water.
- Ketoprofen is marketed as an IM 100 mg/2 mL formulation (Profenid ® , France, Aventis, Oruvail ® , Hawgreen, UK) and as a lyophilized powder for intravenous use.
- the maximum daily dose by this route is 300 mg.
- the IM formulation containing benzyl alcohol
- This formulation is approved for deep intramuscular injection into the gluteal muscle, 50- 100 mg every 4 hours (max. 200 mg in 24 hours) for up to 3 days.
- an intramuscular (IM) form of ketoprofen is also available for deep intramuscular injection into the gluteus muscle.
- IM intramuscular
- IM solution containing arginine, benzyl alcohol, citric acid, and water for injection
- its use by the IV route is prohibited due to toxicity of the formulation.
- IM administration does not provide a very rapid onset of effect, and it is painful, especially with repeated administration or with a large injection volume.
- Most clinicians and hospitals discourage the repeated IM administration of drugs and the use of IM injection volumes greater than 1 mL.
- IM injection volumes greater than 2 mL are generally strongly discouraged or prohibited from routine use.
- IM administration is not appropriate in many patients due to an absence of adequate muscle mass and the possibility of bleeding and hematoma formation, especially if anticoagulated with drugs like heparin or warfarin.
- IM administration of the acid formulation of NSAIDs has also been associated with sever nerve damage, muscle tissue necrosis, and even death.
- a separate IV formulation of racemic ketoprofen is available in a few countries as a lyophilized powder containing sodium hydroxide, glycine, and citric acid. It is recommended by the manufacturer that IV ketoprofen be diluted in 100 to 150 mL of 5% dextrose in water or 0.9% saline and administered over approximately 20 minutes.
- IV ketoprofen be diluted in 100 to 150 mL of 5% dextrose in water or 0.9% saline and administered over approximately 20 minutes.
- an infusion of ketoprofen over 20 minutes means that the onset of analgesia is delayed and the peak pain relief is lower, owing to lower maximal blood concentrations.
- ketoprofen can cause significant side effects, including venous irritation.
- side effects including venous irritation.
- venous irritation e.g., Castagnera, L., et al., Sem Hop Paris 64(32):2179- 2182 (1988); Semaine des hospitaux (Paris) 32:2179-88 (1988)).
- ketoprofen by the intravenous route has been limited by the porr solubility of the drug, the need to administer it in a large volume of solution (100 to 150 mL), the need to infuse the dose over 15 to 20 minutes and the need to use solubilizers that can be toxic and that can result in drug precipitation upon injection.
- PCT Patent application number PCT/US2006/016078 discloses novel formulations of ketoprofen, dexketoprofen, piroxicam and tenoxicam, with ethylenediamine and/or piperazine.
- Piroxicam is an N-heterocyclic carboxamide of 1,2 benzothiazine 1,1 dioxide with analgesic and anti-inflammatory activity. It has an extended half-life of about 40 hours and is suitable for once daily administration. It is primarily biotransformed in the liver to inactive metabolites; less than 10% of a dose appears unchanged in the urine. Evidence from clinical trials indicates that piroxicam 20 mg per day is comparable to daily doses of aspirin 3 to 6 g, indomethacin 75 to 150 mg, naproxen 500 mg, ibuprofen 1200 to 2400 mg, diclofenac 75 mg and fenbufen 600 mg.
- Piroxicam has demonstrated efficacy in rheumatoid arthritis, osteoarthritis, acute gouty arthritis, ankylosing spondylitis, acute musculoskeletal disorders, dysmenorrhea, renal colic and acute postsurgical pain.
- the usual adult dose of oral piroxicam is 20 to 40 mg given once a day.
- 1,1 -dioxide is an NSAID with an oxicam structure, is entirely ionized at physiological pH, has minimal lipophilic properties, high plasma protein binding, does not accumulate in fatty tissue and skin and thus has a small volume of distribution. It is completely absorbed via the oral route and is about 99% protein bound in human plasma. Food consumption delays its rate of absorption without affecting its bioavailability. An elimination half-life of 50 to 80 hours has been estimated. Tenoxicam demonstrates linear pharmacokinetics over the 10 to 100 mg dose range. As a consequence of its low lipophilicity and high percent ionization, tenoxicam is poorly distributed into body tissues. Tenoxicam is primarily biotransformed in the liver.
- tenoxicam demonstrates linear pharmacokinetics during multiple- dosing. As a result of its long half-life, tenoxicam can be administered once daily. Clinical trials in patients with rheumatoid arthritis, osteoarthritis, ankylosing spondylitis and gout suggest that tenoxicam 20 mg daily is an effective anti-inflammatory and analgesic agent. Gastrointestinal symptoms are the most frequently reported side effects. Compared with many other NSAIDs, tenoxicam offers certain advantages in that it is conveniently administered once daily and dosage adjustment is not required in the elderly or in patients with renal or hepatic.
- Ketorolac ( ⁇ )-5-Benzoyl-2,3-dihydro-lH-pyrrolizine-l-carboxylic acid) is a chiral NSAID which is marketed for analgesia as the racemate. It is administered as the water soluble tromethamine salt and is available in tablets or as an intramuscular and intravenous injection. The absorption of ketorolac is rapid, with peak plasma concentrations occurring between 20 to 60 minutes post-dose. The oral bioavailability of ketorolac is estimated to range from 80 to 100%. The drug is extensively bound to plasma proteins and has a volume of distribution comparable to other NSAIDs. The elimination half-life is between 4 and 6h.
- Ketorolac is extensively metabolized through glucuronidation and oxidation and very little is excreted unchanged. Most of the dose of ketorolac is recovered in the urine as conjugate. Ketorolac is the only nonsteroidal antiinflammatory drug (NSAID) in widespread clinical use that is available in an injectable form. Ketorolac is presently the only NSAID available in parenteral form in the United States.
- NSAID nonsteroidal antiinflammatory drug
- ketorolac provides efficacy comparable to that standard doses of opioid analgesics.
- parenteral ketorolac has demonstrated efficacy in patients with renal colic, migraine headache and musculoskeletal pain.
- the utility of ketorolac in acute pain is somewhat limited due to a prolonged time to onset of analgesia.
- the clinical utility of parenteral ketorolac is limited due to its adverse effect profile and a restriction on duration of use. In a number of countries, injectable ketorolac has been withdrawn from the market by the local health authorities, due to its high propensity to cause serious and life threatening side effects.
- Diclofenac (2-[(2,6-Dichlorophenyl)amino]benzeneacetic acid) is an effective analgesic, antipyretic, and anti-inflammatory. It is rapidly absorbed after oral administration, undergoes extensive protein binding and has a short half-life. It undergoes significant first-pass metabolism, with approximately 50% of the dose biotransformed upon first pass through the liver. Diclofenac is metabolized in the liver by CYP2C to 4-hydroxydiclofenac, its primary metabolite, and to other hydroxylated forms. Following glucuronidation and sulfation the metabolites are excreted in the urine and bile.
- Diclofenac is approved in the United States for the long-term symptomatic treatment of rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. Diclofenac has also been extensively studied in the short-term treatment of acute musculoskeletal pain, postsurgical pain and dysmenorrhea. The major adverse events with diclofenac are gastrointestinal (approximately 20%). Elevations in hepatic transaminases occur in a significant number of patients. In some patients, transaminase levels may increase more than 3-fold. Other side effects of diclofenac include rashes, allergic reactions, fluid retention and edema. Among available NSAIDs, diclofenac appears to have the greatest risk of adverse cardiovascular outcomes.
- Ibuprofen ( ⁇ -Methyl-4-(isobutyl)phenylacetic acid), the most commonly used
- NSAID in the United States was the first member of the propionic acid class of NSAIDs to become commercially available.
- Naproxen, flurbiprofen, fenoprofen, ketoprofen, and oxaprozin are other drugs in the propionic acid class of NSAIDs that have been widely commercialized.
- Naproxen has a longer half-life than ibuprofen.
- Oxaprozin also has a long half-life and may be given once daily.
- Propionic acid derivatives are approved for use in the symptomatic treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, acute gouty arthritis and acute pain (e.g., postsurgical pain, musculoskeletal pain, primary dysmenorrhea).
- the pharmacodynamics of the propionic acid derivatives do not differ greatly.
- Ibuprofen has a half-life of approximately 2 hours. It is rapidly absorbed and undergoes significant hepatic biotransformation, followed by renal excretion of metabolites. Gastrointestinal adverse events are common with ibuprofen. Other side effects include rashes, headache, dizziness, fluid retention, and edema.
- Ibuprofen has demonstrated efficacy in rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, acute gouty arthritis and acute pain.
- Naproxen ((iS)-(+)-2-(6-Methoxy-2-naphthyl)propionic acid) is almost completely absorbed upon oral administration. Food delays the rate of absorption. Peak naproxen concentrations in plasma occur within 2 to 4 hours. Naproxen is about 99% protein bound. The half-life of naproxen in plasma is about 14 hours in the young, with a 2-fold increase observed in elderly patients. Approximately one-third of the dose of naproxen undergoes 6-demethylation. This metabolite, along with naproxen is excreted as conjugated products. Gastrointestinal side effects are common. Other side effects include drowsiness, headache, dizziness and fatigue. Naproxen has demonstrated efficacy in rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, acute gouty arthritis and acute pain.
- Flurbiprofen (2-Fluoro- ⁇ -methyl-4-biphenylacetic acid ) is a chiral NSAlD of the
- Flurbiprofen has demonstrated efficacy in rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, acute gouty arthritis and acute pain.
- Side effects include hypertension, congestive heart failure, gastrointestinal ulceration, bleeding and perforation, renal and hepatic impairment.
- Lornoxicam (6-Choloro-4-Hydroxy-2-methyl-N-2-pyridinyl-2H-thieno(2,3-e)- l,2-thiazine-3-carboxamide 1,1 -dioxide or chlorotenoxicam) is a nonsteroidal antiinflammatory drug of the oxicam class. Unlike other oxicams, lornoxicam has a relatively short plasma half-life (of approximately 3 to 5 hours. Lornoxicam is eliminated through hepatic metabolism to 5'-hydroxylornoxicam. Lornoxicam' s metabolites are excreted in urine and feces. Lornoxicam and its major metabolites bind extensively to plasma proteins. Lornoxicam has been shown to be effective in the treatment of acute and chronic pain, including postsurgical pain and osteoarthritis. Lornoxicam's side effects are consistent with its NDAIS pharmacology.
- the rate of absorption of celecoxib is moderate when given orally, with a Cmax of approximately 2 to 4 hours.
- Celecoxib is extensively protein bound, primarily to plasma albumin, and has an apparent volume of distribution of 455 ⁇ 166 L.
- the extent of absorption of celecoxib increases in proportion to increasing oral doses between 100 and 800 mg. It is eliminated following biotransformation to carboxylic acid and glucuronic acid metabolites that are excreted in urine and feces.
- Celecoxib has an elimination half-life of approximately 11 hours in healthy individuals. In randomized clinical trials, celecoxib is superior to placebo and similar in efficacy as conventional NSAIDS for osteoarthritis and rheumatoid arthritis.
- celecoxib 100 and 200 mg and naproxen 500 mg twice daily provide similarly efficacy.
- celecoxib 200 mg twice daily shows efficacy comparable to twice daily slow-release diclofenac 75 mg over a 24-week period.
- Parecoxib a prodrug of valdecoxib is the only parenterally administered cyclooxygenase-2-selective inhibitor available. The recommended dose is 40 mg administered IV or IM, followed every 6 to 12 hours by 20 mg or 40 mg as required, not to exceed 80 mg/day. Clinical trials of parecoxib demonstrate compareable efficacy with ketorolac in a variety of postsurgical pain states. However, parecoxib has significant adverse cardiovascular risk (Babul et al, Anesthesia and Analgesia 2006; 102:644-56; Babul et al., Anesthesiology 2006;104:375).
- Lumiracoxib is a selective COX-2 inhibitor with an oral bioavailability of 74%. It is rapidly absorbed, reaching maximum plasma concentrations 2 hours after dosing, and is highly plasma protein bound. It has a short elimination half-life from plasma of approximately 4 hours and demonstrates dose-proportional plasma pharmacokinetics. Lumiracoxib is extensively metabolized prior to excretion, with only a small amount excreted unchanged in urine or feces. COX-2 selectivity of lumiracoxib is associated with a reduced incidence of gastroduodenal erosions compared with naproxen.
- lumiracoxib 100 to 200 mg per day has been shown to be superior to placebo in patients with osteoarthritis, with clinical efficacy comparable to diclofenac 150 mg/day, celecoxib 200 mg/day and rofecoxib 25 mg/day.
- lumiracoxib 400 mg/day is as effective as standard doses of NSAIDs and other coxibs. Liver function test abnormalities were more frequent with lumiracoxib than with the comparator NSAIDS. There are no data on the efficcay of parenterally administered lumiracoxib. Lumiracoxib has been withdrawn from the market in a number of countries due to serious hepatic adverse effects.
- Etoricoxib is a selective inhibitor of COX-2. Extensive clinical trials have confirmed its analgesic and antiinflammatory efficacy to be comparable to nonselective NSAIDS. Like other COX-2 selective NSAIDS, etoricoxib displays improved gastrointestinal safety compared with nonselective NSAIDS. It is rapidly and completely absorbed following oral administration providing a rapid onset of action. Its long plasma half-life allows for once-daily dosing. Etoricoxib is currently approved in a number of countries for various indications including the treatment of acute pain, acute gouty arthritis, chronic back pain, dysmenorrhea, osteoarthritis and rheumatoid arthritis.
- etoricoxib is 30 mg once daily (maximum daily dose, 60 mg) for OA, 90 mg once daily for RA (maximum daily dose, 90 mg) and 120 mg once daily for acute gouty arthritis (maximum daily dose, 120 mg for up to 8 days).
- the aforementioned selected NSAIDs including the preferred NSAIDs have one or more of the drawbacks associated with administering the NSAIDs.
- a majority of NSAIDs have never been administered parenterally. Whether administered parenterally or orally, the prior art provides guidance on the effective dose range that may be safely administered (i.e., that achieve a balance between the attainment of the desired therapeutic effects and an "acceptable” or “tolerable” level of adverse effects.

- Administration of the present invention can be via any parenteral route of administration.
- suitable parenteral routes of administration are described in general terms as follows. Each of the following routes of administration can be used in the present invention, in particular in each of the specific embodiments described.
- IM Administration Once a popular method of drug administration, the intramuscular (IM) route is used considerably less frequently today due to improved availability of oral drugs and due to the ease of intravenous administration. This method of drug administration involves injecting drug directly into muscle mass, from where drug will gradually be absorbed systemically. For drugs that are not irritating when given by the IM route which require only a single injection, the IM route is still a viable route of administration, particularly in the outpatient setting or when strict aseptic conditions cannot be assured. When repeated administration is required or a rapid and reliable onset is desired, the intravenous route is preferred as repeated IM administration can be painful and inconvenient. Commonly the deltoid, gluteus maximus and vastus lateralis are sites for IM injection.
- IM administration is partly a function of the dose and the injection volume, both of which are reduced by ULD NSAIDS of the invention. Additionally, IM administration is particularly attractive in the ambulatory care/outpatient setting, where venous access is lacking or impractical, and in settings where sterility cannot be absolutely assured.
- the reduced dose and volume of the ULD NSAIDS of the invention particularly facilitate deltoid injections which are more convenient, more socially acceptable and provide more reliable pharmacokinetics and clinical effects that injection into the gluteus maximus.
- Subcutaneous Administration involves injection into the subcutaneous fatty tissue under the skin. It can be used for the intermittent administration and self-administration of insulin and other medicines. In a small number of patients, particularly outpatients, this route is also used for the continuous or intermittent administration of drugs, usually with a programmable subcutaneous infusion device.
- Epidural and intrathecal infusions can provide effective analgesia, but require skilled personnel (usually an anesthetist) to put the systems in place.
- Catheters can be placed at any level of the spinal cord, although most commonly these techniques are used for pain in the lower part of the body.
- Epidural and intrathecal routes of administration are advantageous for difficult abdominal or pelvic pain.
- epidural catheters can be placed percutaneously, and fixed either by secure taping or subcutaneous tunnelling. The drugs can then be delivered through a small pump or a syringe driver. Subjects can be ambulant and managed at home with these systems. However the treatment team must have the necessary training, knowledge and support.
- intrathecal systems which can be fully implantable, have many advantages. These offer great freedom to the patient, as there is no external equipment and the pump only needs to be refilled every few weeks. Some of the pumps are programmable and offer great flexibility.
- epidural and especially intrathecal doses of NSAIDs can be lower than intravenous doses.
- Epidural and intrathecal administration of NSAIDs can be also be used in conjunction with intravenous NSAIDs to provide additive or synergistic analgesia.
- Intraarticular Administration This method of administration can be used to provide analgesic and anti-inflammatory drugs directly into affected joints to relieve pain and inflammation, usually due to surgery, osteoarthritis or joint trauma.
- Surgical site or open wound This method of administration can be used when localized attenuation of pain or inflammation is deemed desirable and is achieved by topical, dermal administration or infiltration of a dose to a surgical site or open wound.
- the term "infiltration”, “local infiltration”, “tissue infiltration” and “local tissue infiltration” shall mean administration into a discrete surgical site, open wound or at the location of pain in a human or animal.
- IV Drug Administration The mode of IV drug administration depends on the particular NSAID used, the patient's condition, and the desired clinical effects of the NSAID.
- the four primary modes of IV drug administration are continuous infusion, intermittent infusion, direct injection, and patient-controlled analgesia.
- Continuous infusion typically refers to the admixture of a drug in a large volume of solution that is infused continuously over several hours to several days.
- the solution container is connected to an administration set, and the solubilized drug is infused through the venous access.
- the infusion may be administered by gravity feed or by use of electronic infusion control pump to deliver the drug accurately.
- continuous infusions can be used when the drug is highly diluted and constant plasma drug concentration should be maintained.
- continuous infusion can be used where large volumes of fluids and electrolytes need to be replenished along with the administration of the NSAID.
- Intermittent infusion refers to the administration of the drug as a small volume of fluid, typically 25 to 250 mL in adults, and infused over, for example, 15 to 120 minutes at periodic intervals.
- advantages of the intermittent method are the ability of the drug to produce higher peak blood concentrations at periodic intervals (compared with a continuous infusion), decreased risk of fluid overload, and greater convenience for the patient.
- Intermittent infusions may be given in a number of ways, including "piggyback" infusions through the established pathway of a primary infusion solution. Although the primary infusion is interrupted during the piggyback infusion, the drug from the intermittent infusion container mixes with the primary solution below the piggyback injection level. Thus, if this method is used, the drug and the primary solution must be compatible.
- a second method to administer intermittent infusions is as a simultaneous infusion, where the drug is administered as a secondary infusion concurrently with the primary infusion. Instead of connecting the intermittent infusion at the piggyback port, it is attached to a lower secondary port.
- One potential disadvantage of this method is the tendency for blood to back up into the tubing once the secondary infusion has been completed, potentially occluding the venous access device. This generally does not occur with the piggyback method because the hydrostatic pressure closes the back check valve once the intermittent infusion is completed.
- a third method is the use of a volume control set. Although it was originally designed to control the fluid volume delivered to the patient, a drug may be added to a small amount of solution in the volume control set and infused at the desired rate. It is still used in some pediatric settings because it limits the amount of fluid the child receives.
- a fourth method for administering intermittent infusions is directly into the venous access device.
- the device is generally intended for intermittent administration, such as a peripheral heparin lock.
- the drug is added to a minibag or minibottle and infused intermittently. Between doses, the drug container and tubing are discarded.
- Direct injection also known as IV push, IV bolus, or slow IV injection
- IV push is the administration of a drug directly into the venous access device or through the proximal port of a continuous infusion set.
- a purpose is to achieve rapid plasma concentrations while avoiding costly and time consuming use of infusion devices.
- a direct injection requires only the time it takes to push the syringe plunger. Since the drug may be incompatible with the infusing solution or heparin may be present in the intermittent device, the vascular access device can be flushed with normal saline before and after injecting the drug.
- Direct injections may require that the drug be drawn into a syringe before administration or that the drug be available in a prefilled syringe.
- a needle 1 inch or shorter should be used to administer the medication because longer needles may puncture the IV tubing or the vascular access device.
- Another alternative is a needleless system, which also prevents inadvertent puncture of the tubing or device.
- Patient-controlled analgesia e.g., patient controlled intravenous analgesia [PCA] or patient controlled epidural analgesia [PCEA], or patient controlled analgesia using the intrathecal or subcutaneous route of administration
- PCA patient controlled intravenous analgesia
- PCEA patient controlled epidural analgesia
- patient controlled analgesia using the intrathecal or subcutaneous route of administration is the fourth method of administration of drug administration which promotes patient comfort through the self- administration of analgesic agents.
- an automated pump is programmed to administer a small bolus of the drug when activated by the patient.
- the bolus amount (demand dose) and the time between doses (lock-out interval) are predetermined and programmed into the pump.
- a demand dose or bolus amount of drug administered whenever the patient presses a button includes (1) a demand dose or bolus amount of drug administered whenever the patient presses a button; (2) a lockout interval which determines how soon after a bolus is administered a second bolus will be delivered if the patient pushes the button again; and optionally (3) a daily or 24 hour maximum dose or a daily or 24 hour maximum number of demand doses; and (4) override doses, said override doses administered by or under the supervision of a qualified care giver or health care worker . If a patient presses the button before the lockout interval has elapsed, the pump simply ignores the request.
- the dose and lockout are generally programmed into the pump for an individual patient and drug combination.
- the dose is prescribed based on the clinician's assessment of the patient's opioid requirement (depending on weight, habituation, or other factors).
- the lockout interval is generally set depending on the time to onset of clinical effect of a given drug.
- the lockout interval is used to prevent a patient from giving himself or herself another bolus before the previous bolus has had a chance to take effect.
- PCA refers to patient controlled analgesia by the intravenous route
- PCEA refers patient controlled analgesia by the epidural route.
- a co-administered drug may include other NSAIDs, NO-NSAIDs, COX-2 selective inhibitors, acetaminophen, nitroparacentamol, tramadol, local anesthetics, antidepressants, beta adrenergic agonists, alpha-2 agonists, selective prostanoid receptor antagonists, cannabinoid agonists, opioid receptor agonists, NO-opioids, NMDA receptor antagonists, gabapentin, pregabalin, gabapentinoids, neuronal nicotinic receptor agonists, calcium channel antagonists, sodium channel blockers, serotonin 5-HT(lB/lD) receptor agonists superoxide dismutase mimetics, p38 MAP kinase inhibitors, triptans, TRPVl agonists, dextromethorphan, dextrorphan, ketamine, glycine receptor antagonists,

- compositions of the present invention can be evaluated in one or more of the tests described below:
- the tail-flick test is considered to be very robust in that weak analgesic agents are not detected by this test. In contrast, it is considered highly selective. There is a high degree of correlation between drugs that are identified as antinociceptive in the tail-flick test and clinically active analgesic agents. It is especially predictive of rank-order of potency of opioid-type analgesic agents, and the clinically effective dose of a novel opioid may be predicted by the relative potency of the drug to a known substance, such as morphine, based on this assay. Importantly, agents that are sedating and may produce a positive response in the writhing test or hot plate test do not show antinociceptive activity in the tail-flick test. It is even possible to perform the tail-flick test in lightly anesthetized animals.
- the raw tail withdrawal latencies are converted to a %MPE (% maximal possible effect) by the formula:
- % MPE 100 x (test latency - basal latency)/(cut-off- basal latency).
- This formula constrains the data to fit between 0% MPE and 100 % MPE. This allows the generation of dose-response curves and the calculation of ED 50 values (50% effective doses) with attendant confidence intervals. These calculations then allow for the determination of relative potencies of different drugs and allow for the isobolographic determination of possible synergistic effects. Instances where the test latency is less than the basal latency produces a negative % MPE, which is meaningless unless one is measuring hyperalgesia. By convention, these values are set to 0% MPE when the expected drug effect is antinociception or no activity.
- the standard protocol for the evaluation of tactile hyperesthesia is to determine the paw withdrawal threshold of the hindpaw of the rats in response to probing with von Frey filaments.
- Thermal hyperalgesia is indicated by a significant reduction in paw withdrawal latency to noxious radiant heat projected onto the plantar aspect of the hindpaw of the rat.
- Tests are conducted with systemic (SC) and intrathecal (IT) administration.
- SC systemic
- IT intrathecal
- sham-operated animals are also required. Since sham-operated rats do not develop tactile hyperesthesia, only responses to thermal stimuli are tested. Testing of sham-operated rats requires an additional 48 animals. Approximately 26 rats are be used for initial dose-finding experiments. Animals are tested within 7 to 10 days of SNL. Surgery and testing may be staggered to optimize testing efficiency.
- the intrathecal drug administration studies require implantation of catheters 7 days prior to the SNL surgery, and testing at 10 days after SNL surgery.
- Models of inflammation that produce more persistent pain include the injection of carrageenan into the footpad of the limb; the potential analgesic and/or anti-inflammatory properties of putative analgesics substances can be evaluated in this model. See generally Bhalla T.N. & Tangri, K.K. "The time course of the carrageenan-induced oedema of the paw of the rat.” J. Pharm. Pharmacol. 22:721 (1970); Randall, L.O. & Selitto, J.J., "A method for measurement of analgesic activity on inflamed tissue," Arch. Int. Pharmacodyn. Ther. //7:409-419 (1957); Hargreaves, K., et al. "A new and sensitive method for measuring thermal nociception in cutaneous hyperalgesia.” Pain 32:77-88 (1988).
- rats are handled and acclimatized to the behavioral testing equipment over a minimum of 2 days prior to testing. Behavioral tests are performed on all rats on the day prior to dosing to establish baseline values, and the animals are randomized into treatment groups based on these pre-dose responses.
- An assessment of the inflammatory agent (carrageenan) is performed prior to the main study, using the chosen behavioral tests. On the day of dosing, an inflammatory response is induced in the left hind paw of each rat by an intraplantar injection (approx. 0.05 mL) of carrageenan (0.6% w/v), under brief anesthesia.
- the test substance, reference substance, or vehicle is generally administered 30 minutes prior to carrageenan administration for oral dosing.
- Paw Volume Each animal is gently restrained, their hind limb extended, and the paw placed in the pre-filled chamber of a Digital Plethysmometer. The paw volume is then calculated based on the volume of liquid displaced in the chamber, for both the ipsilateral and contralateral hind paws.
- Pain intensity (VAS and categorical), pain relief (categorical) and whether pain is half-gone is recorded by the patient under the supervision of the investigator or study coordinator at the various time points: Baseline (0 hour - pain intensity only), 15, 30 and 45 minutes, and at 1, 1.5, 2, 3, 4, 5, 6, 7, 8 and 12 hours after administration of study medication, and immediately prior to the first rescue dose. Time to onset of perceptible and meaningful pain relief is evaluated using the two stopwatch method. Patients record their global evaluation of study medication at the completion of the 8-hour assessment or at the time of first rescue medication use.

- the time required for each solution to pass between two marks on the viscometer was used to determine the relative velocity. Density was measured separately for the solutions. Water was used as reference liquid (viscosity of water at 20° C is 1.002 cP).
- C j is the concentration of the ionic species
- Z j is the charge on the ionic species
- Ketoprofen at a flow rate of 5 mL/min was introduced to ISPB flowing at a rate of 5 mL/min in a tube for 30 seconds and passed through a flowcell. Absorbance was measured at 540 nm using a UV spectrophotometer. The wavelength 540 nm was chosen since all the formulations had no or very small absorbance at that wavelength. The results were compared with ketoprofen- ethylenediamine and ketoprofen-piperazine (without any pH adjustment or additives). [00481] The absorbance from the unsalified pH adjusted ketoprofen was a 83-fold and
- ketoprofen as the ethylenediamine salt (0.1 M) at an initial concentration of 50 mg/mL and ketoprofen as the piperazine crystalline salt at an intial concentration of 10 mg/mL were retested after 3 months storage at room temperature using an HPLC analytical method. There was no significant degradation of ketoprofen. The detected concentration of ketoprofen after three months was 49.4 mg/mL (98.8%) and 9.94 mg/mL (99.4%) for ketoprofen-ethylenediamine and ketoprofen-piperazine, respectively, which is within the range of experimental error.
- Ketoprofen solution at a concentration of 50 mg/mL was prepared in 0.1 N NaOH. The pH was gradually increased over 4 hours in order to avoid the presence of excess sodium hydroxide. The pH was increased using solid sodium hydroxide. The final pH of the solution was 8.72 (constant over 12 hours). The solution was filtered with a 0.45 ⁇ m syringe filter into a sterile evacuated vial.

- AEs Adverse events
- Diagnosis and main criteria for inclusion Male and female patients, 18 to 40 years of age (inclusive), and with a body weight of 50 kg to 115 kg (inclusive) who had surgical extraction of 2 or more third molars were eligible provided that one was a bony impacted mandibular third molar, and if only 2 third molars were extracted, they were ipsilateral. Qualified patients had moderate or severe pain within 6 hours of completion of surgery as measured by the categorical PI scale and a VAS measurement for PI of > 50 mm at Baseline. Patients provided written informed consent prior to participation in the study, were in good health as determined by the Investigator, and demonstrated the ability to properly complete the pain assessments, to understand the English language, and to cooperate with study procedures. Female patients of childbearing potential were non- lactating, had a negative urine pregnancy test within 24 hours before surgery, and practiced abstinence or a medically acceptable form of contraception.
- Efficacy was total pain relief (TOTPAR) over the
- ITT insulin therapy population
- ITT patient-derived neurodegenerative disease population
- PI post baseline PI or PR measurement.
- Patients who took rescue medication within 60 minutes after dosing were included in the ITT population.
- Each efficacy variable had multiple comparisons performed using Fisher's protected least significance (PLSD) in order to control for the comparison-wise error rate. If a variable was measured over multiple intervals, this was done for each interval.
- the overall 2- sided test i.e., F, or log-rank
- TOTPAR, SPID, SPRID, and time-specific PID, PR, and PRID were analyzed using an analysis of variance (ANOVA) model with effects for treatment and baseline pain stratification.
- ANOVA analysis of variance
- the time to perceptible pain relief was the time recorded by the first stopwatch, and the time to meaningful pain relief was the time recorded by the second stopwatch.
- Time to confirmed perceptible pain relief was defined as the time to perceptible pain relief only if both perceptible and meaningful pain relief were experienced.
- Time to perceptible pain relief, confirmed perceptible, meaningful pain relief; time to re- medication; time to first change from the Baseline assessment in PID (categorical) of > 1 ; and time to pain half gone were estimated using Kaplan-Meier method. Summary information including the median time estimates and 95% confidence intervals on the median time for the above time variables was provided using Kaplan-Meier methodology and the method of Simon and Lee, and treatment groups were compared using the log- rank test.
- Peak PID, peak PR, and the patient global evaluation were analyzed using the stratified rank-sum test, stratified by baseline pain. The proportions of patients with 50% pain gone, with meaningful pain relief, and re-medicated were analyzed using the Chi- square test. [00518] The safety analyses were conducted on the treated patient population, defined as all randomized patients who received study medication. Safety measures were summarized using descriptive statistics.
- ketoprofen 100 mg (the minimum approved dose of IV ketoprofen); ketoprofen 50 mg (50% of the minimum approved dose of IV ketoprofen); tramadol 150 mg (150% of the maximum approved dose of bolus IV tramadol; tramadol 100 mg (the maximum approved dose of bolus IV tramadol); and morphine 4 mg (the maximum recommended bolus dose of IV morphine).
- ketoprofen 50 mg or 100 mg demonstrated efficacy results that were statistically significantly superior to those of a single IV dose of placebo or morphine 4 mg for all efficacy measures, and significantly superior to a single IV dose of tramadol 100 mg or tramadol 150 mg for almost all efficacy measures.
- ketoprofen 50 mg or 100 mg received a global evaluation of
- the proportions of patients with at least one adverse event for ketoprofen 50 mg, and ketoprofen 100 mg groups was 60.6%, and 64.5%, respectively.
- the proportions of patients with at least one adverse event for morphine 4 mg, tramadol 100 mg and tramadol 150 mg was 72.7%, 72.7% and 86.4%, respectively
- ketoprofen groups were mild or moderate in intensity; only 1/33 patients treated with ketoprofen 50 mg had severe adverse events (dry mouth [dry socket] and postoperative infection), and 2/31 patients treated with ketoprofen 100 mg reported one severe adverse event each (application site swelling and abdominal pain).
- the majority of adverse events in the tramadol 100 mg group were mild or moderate; whereas, all adverse events in the tramadol 150 mg group were moderate or severe.
- Five of 33 patients in the 100 mg group and 13/22 patients in the 150 mg group had severe adverse events.
- Three of 33 patients in the morphine 4 mg group had severe adverse events.
- Ketoprofen by IV bolus at 50% of the minimum approved dose (50 mg) provided almost identical efficacy on all tested parameters, when compared with the minimum approved IV dose (100 mg) of ketoprofen. Both ketoprofen by IV bolus at 50% of the minimum approved dose (50 mg) and ketoprofen at the minimum approved IV dose (100 mg) provided far superior efficacy when compared with the maximum recommended bolus IV morphine dose (4 mg), the maximum approved IV bolus dose of tramadol (100 mg), and 150% of the maximum approved IV bolus dose of tramadol (150 mg), P ⁇ 0.05 to ⁇ 0.001.
