Background of invention
An enzyme family that is called as nitricoxide synthase (NOS) is from the synthetic nitric oxide (NO) of L-arginine-a kind of important second message,second messenger's biology.NOS has several different isotypes, comprises composition NOS (cNOS) and derivable NOS (iNOS).Two kinds of different cNOS are arranged: epidermis NOS (eNOS) and neuronal NOS (nNOS).ENOS participates in smooth muscle loosening, blood pressure reduces and the adjusting of the inhibition of platelet aggregation.ENOS is present in endotheliocyte and at responsive cell Ca 2+Receptor-mediated increase in the NO of release in a short time.People such as Michel, " nitric oxide is synthetic: which, where, how and why? " J.Clin.Invest 100:2146-2152 (1997).NNOS is important for long-term enhancing, and the dependence Ca of responsible nerve unit 2+Release.INOS works in host defense, and produce by activatory macrophage during the immunne response, in vascular smooth muscle cell, induce (for example, by various cytokines, microbial product, and/or bacterial endotoxin), and in a single day express just long-time synthetic NO.
Think in the endotheliocyte that forming nitric oxide by cNOS regulates, prevents that endothelial function is unusual plays an important role in as hyperlipemia, arteriosclerosis, thrombosis and restenosis in normal arterial pressure.CNOS is the main synthase that exists in brain and the epithelium, on function, cNOS has activity and can further stimulate by the increase of intracellular Ca2+ under basic condition, wherein the increase of the intracellular Ca2+ agonist or the Calcium ionophore of replying receptor-mediation takes place.CNOS seemingly this enzyme " physiology " form and in various groups of biological process, work.In vitro study shows that nitric oxide self can regulate the activity of NOS in degenerative mode.In the circulation of heart and brain kidney blood vessel, think that the main target of the NO that composition produces is soluble guanylate cyclase, it is arranged in vascular smooth muscle, cardiac muscle (myocyte) and coronary vasodilator smooth muscle.
Compare with cNOS, isotype iNOS derivable, that rely on calcium only describes in macrophage at first.The inducing of it is now know that nitricoxide synthase can be replied the adequate stimulus in many other cell types and be taken place.This is induced and can as taking place in the vascular smooth muscle cell, can also take place in the cell such as the cardiac muscle of expressing high-caliber composition isotype at the cell of not expressing the composition form of nitricoxide synthase usually.
INOS demonstrates negligible activity under basic condition, but when the factor of replying such as lipopolysaccharide and some cytokine, expresses in several hours time.The inductive form of this enzyme produces the NO amount more much bigger than composition form, and derivative NOS " Pathophysiology " form of this enzyme seemingly, because the NO pair cell that high concentration iNOS produces is deleterious.Can suppress inducing of iNOS by glucocorticoid and some cytokine.Know less relatively regulated in the back of transcribing about iNOS.The cytotoxic effect that NO causes may be independent of guanylate cyclase to a great extent and cyclo GMP forms.Major part research in this field concentrates on uses the arginic various derivants of L-to stimulate the iNOS inhibitor.
NO is from molecular oxygen and the synthetic metastable free radical of the arginic guanidine radicals nitrogen of L-in the catalytic reaction of NOS.Find this enzyme in many tissues and cell type, these cell types comprise the endotheliocyte of neuron, macrophage, hepatocyte, smooth muscle cell, blood vessel and the epithelial cell of kidney.NO acts near its point of release, enters target cell and activates cytosol enzyme guanylate cyclase, the formation of guanylate cyclase catalysis second message,second messenger cyclo GMP (cGMP).In the several seconds that NO forms, its experience is oxidized to nitrite or nitrate.David L.Nelson, Michael M.Cox, Lehninger Principles of Biochemistry, 892 pages, third edition Worth Publishers, 2000.
Replying various vasoactive agents, even during physiological stimulation, endotheliocyte discharges a kind of short-lived vasodilation that is called the deutero-relaxation factor of endotheliocyte (EDRF) and (is also referred to as the nitric oxide (EDNO) in endotheliocyte source.The product of inflammation and platelet aggregation such as 5-hydroxy tryptamine, histamine, Kallidin I, purine and thrombin are by stimulating their all or part effect of release performance of NO.The mechanism of lax dependence endotheliocyte comprises in the coronary circulation it being important in various vascular bedes.People such as Hobbs, Annu.Rev.Pharmacol.Toxicol.39:191-220 (1999).NO can easily be diffused into following smooth muscle and increase cGMP concentration by the activation guanylate cyclase, thereby the induction of vascular smooth muscle is lax.
NO is responsible for relying on neurotransmission and activatory macrophage cytotoxicity in activation, maincenter and the peripheral nervous system of lax and soluble guanylate cyclase of endotheliocyte.In vasculature, EDNO has several effects, comprising the inhibition of platelet aggregation, the adhesion of inflammatory cell and the propagation of smooth muscle cell.Particularly, EDNO is the important regulator of vascular tone.And, rely on the mediation that mobile diastole (a kind of endothelial function index commonly used) is subjected to NO to a great extent.
To the stimulation of the endotheliocyte of liner vasculature, as acetylcholine, Kallidin I, shearing force, or the like start the regulation mechanism of NO to vascular tone.Catalytic activity by contained eNOS in these endotheliocytes produces NO from the L-arginine.The NO that is produced leaves endotheliocyte and stimulates guanylate cyclase activity in the contiguous smooth muscle cell.The activation of guanylate cyclase has increased the cGMP level and has caused smooth cell lax, thus blood vessel dilating and increasing blood flow.People such as Moncada, New Eng.J.Med.329:2002-2012 (1993); People such as Vallance, J.Royl.Coll.Physician London 28:209-219 (1994).

III. production method
What have been found that L-arginine granule in the substrate effectively and in a large number mixes or covers the sustained releasing character of having improved compositions of the present invention.For cellulose matrix, when contacting with water, this substrate is formed gel layer by the part aquation, the arginic rate of release of its control L-.Effective parcel of L-arginine granule or mix and produced temporary transient dissolving barrier, it has postponed, and L-is arginic to be sent.A large amount of slits make that the dissolving of L-arginine is too fast in the substrate.Method of the present invention causes comparing the product with improved properties with the product that produces by direct compression.In addition, method of the present invention is favourable with respect to comprising that the dispersive method of fluidisation is compared, because these methods are time-consuming and expensive.
Effectively and the key that covers efficiently be to implement granulation of the present invention, mill and blend step in.With reference to figure 5; in preferred embodiments; produce tablet according to a kind of method; this method comprises granulation L-arginine (step 110), the L-arginine (step 125 of milling; 140), the L-arginine is mixed (step 145,150,155) and composition compression formed tablet (step 160) with remaining composition.Preferably, this method also comprise the screening composition (step 105) and/or during the step of milling dry L-arginine (step 135) step one the step or two steps.
If screen composition (step 105) before use, #20 and/or #30 mesh sieve can be used for some or all compositions.In preferred embodiments, in granulation (step 105), and before the (not shown) of milling, screen granule once more.The granule that screening provides has narrower particle size distribution, and this is favourable for coating and/or compression.
Granulation step is favourable, because it provides more homogeneous granules.Use arbitrary suitable method as known in the art to make granular activating agent or granulation.Spheroidizing or granulation are generally defined as the process that size increases, and its small particles is gathered into bigger, persistent aggregation, and wherein original granule still can be identified and make them to become flowable state freely.Before the granulation, bonding agent can be added activating agent to improve granulation.During granulation, can add other additives.These additives comprise, for example, and sweetener, flavoring agent, coloring agent, antioxidant, or the like.
Randomly, can add entry or other solvents to help granulation.The water that is added or the amount of solvent depend on, for example, the selection of granulating method, and those of skill in the art can easily determine.Can during granulation, add entry or other solvents by arbitrary suitable time point.For example, bonding agent can mix to form granulating agent with solvent (for example, water), and granulating agent can be sprayed on the activating agent then.Alternatively, if granulating agent thickness and can not being sprayed to equably on the activating agent too wishes bonding agent is at first mixed with activating agent so, spray water or other solvents are to produce the homogeneous form of activating agent granule or granule then.
Arbitrary suitable granulating method all can be used for producing the granule that contains activating agent.Can use moistening granulation and/or dry granulation method.
Dry granulation refers to the granulation preparation and does not use heat and solvent.The dry granulation technology generally includes slugging or the compression of rolling.Slugging is the dry mixed preparation and said preparation is compressed into bolus or piece agent (slug) on compressor.Gained tablet or piece agent are milled and produce granule.The cylinder compression is similar to slugging, but in the cylinder compression, uses the cylinder compressor to replace pelleter.See, for example, Handbook of Pharmaceutical Granulation Technology, D.M.Parikh editor, Marcel-Dekker, Inc.102-103 page or leaf (1997).The dry granulation technology can be used in some situation, for example, and when activating agent is responsive to heat or solvent.
Alternatively, can use moistening granulation.In moistening granulation, solvent and bonding agent are added into preparation usually so that the bigger gathering of granule to be provided.Temperature during the granulation can be set at arbitrary suitable point, is no more than the fusing point of arbitrary component of said preparation usually.Usually, with this mixture about 35 ℃ under about 65 ℃ temperature granulation less than about 20 minutes, more preferably at room temperature about 1 to about 10 minutes (seeing embodiment 8).Usually with granule suitable time of air drying (for example, one or several hours).
Preferably, by high-shear mixer granulation (" HSG ") or fluid bed granulation (" FBG ") granulation activating agent.These two kinds of granulating methods all provide bigger granule or granule, but they are different on the mechanism of used equipment and this method operation.Use can be implemented these granulation technique by the available device of commercial sources.
In HSG, finish mixing and moistening massing by the high mechanical agitation of impeller or chipper.Realize mixing, the multiviscosisty of moistening material by shearing force that impeller produces and compression stress, and reunite.The major function of chipper is the distribution of piece being cut into littler fragment and helping the liquid bonding agent.The liquid bonding agent is imported into roller or is sprayed on the powder to realize more uniform liquid distribution.
On the other hand, fluidisation is such operation, by the tiny solid of this operation by contact the similar liquids state that is converted to other.Under certain gas velocity, this liquid will be supported these granules, make their freely-movables and not be pulled away.The similar violent ebullient liquid of this fluid bed, the motion that the solid particle experience is very violent, this motion is along with gas velocity increases.Thereby fluid bed granulation is a kind of like this method, by this method, by fluid bed the bonding agent solution spray is formed bigger granule to the fluidized powder bed and has produced granule.Bonding agent solution can be from for example, the spray gun ejection of settling in any suitable mode (for example, top or bottom).Spray position and spray velocity depend on the character of used activating agent and bonding agent, and can easily determine by those skilled in the art.
In according to the preferred method of the present invention, granulation L-arginine (step 110) comprises the L-arginine mixed with bonding agent such as polyvinyl pyrrolidone and forms mixture (step 115), and with mixture and granulating agent (granulation carrier) granulation (step 120) in granulator.Granulating agent can be for example, to be dissolved in the polyvinyl pyrrolidone in the purified water.Preferably, use high shear granulator, as Niro PMA65 high shear granulator.This granulator can be used for mixing L-arginine and bonding agent, after also can be used for being sprayed to the granulation carrier on the mixture with this mixture granulation.
After one or more components of granulation preparation, randomly, the preparation of the granulation of can milling.Can implement to mill with arbitrary suitable available equipment of commercial sources (for example, the CoMil of 0.039 inch sieve of equipment) that passes through.Can select the width of mesh of sieve according to the size of desirable granule.After the activating agent of granulation milled, can be if wish with they further dry (for example, in air).
In preferred embodiments, the L-arginine of milling comprises according to the technology of knowing in this area (sees U.S. Patent number 5 usually, 145,684 and european patent application 498,482, the content of these two applications all is merged in this paper as a reference) the moistening granule of milling or moistening mill (step 125), dry granule (step 130) and mill dry granule or drying mill (step 140).Grinding machine such as CoMil can be used to moistening milling and the drying granule of milling.In one embodiment, grinding machine is used for moistening milling by outfit ' 375Q sieve and be used for drying mills ' 062R sieve.By with granule at bed dryer, for example, be dried to desirable drying loss (LOD) level in the Aeromatic S-2 fluidized bed dryer, for example≤3%LOD, can realize drying steps.(step 135) implements drying steps up to reaching desirable LOD stage by stage.
The L-arginine mixed with remaining composition can comprise pre-blend step (step 145), blend step (step 150) and final blend step (step 155).Pre-blend step can comprise that with L-arginine/polyvinyl pyrrolidone granule and filler and fluidizer for example, microcrystalline Cellulose and colloidal silica mix.For example, in 8 quarts of V-arrangement mixers, mix and to realize pre-blend step in about 5 minutes with 25rpm.Blend step can comprise to this mixture and add one or more slow releasing agents, for example, and one or more hydroxypropyl emthylcelluloses and a kind of filler, for example, microcrystalline Cellulose.Can be in 2 cubic feet of V-arrangement mixers for example mix and to realize blend step in about 20 minutes with 25rpm.Final blend step can comprise that the mixture in 2 cubic feet of V-arrangement mixers adds releasing agent/lubricant, and for example, magnesium stearate was also mixed about 5 minutes with 25rpm.
After having prepared, said preparation compression (step 160) is become tablet form as above-mentioned preparation.By arbitrary suitable method, with or can implement this tablet without compression stress and be shaped.For example; can with arbitrary tablet machine (for example, equipment 0.748 " * 0.380 " oval, projection, the Manesty Beta Press of common die) finish the compression of preparation after the granulation step, preferably; lubricated dose of (for example, magnesium stearate) sufficient lubrication of said preparation compositions.Can utilize the many alternative approach that realize this step, and the present invention is not subjected to the restriction of the use of arbitrary concrete device.Can implement compression step with rotary-type tablet machine.This rotary-type tablet machine has swivel plate, and the latter has a plurality of hole, the perhaps moulds of passing through that are used to form tablet again.Preparation is inserted into this mould also subsequently by pressing mold.
Alternatively, can prepare tablet by molding.In suitable machine, will can prepare the tablet of molding with the moistening pulverulent mixture molding of inert liquid diluent.
The diameter of tablet and shape depend on that selection is used for mould, mold and the punch press of the shaping or the compression of granule composition.Tablet can be dish type, oval, ellipse, circle, cylindrical, triangle, or the like.The tablet scratch can be broken with promotion.Upper surface or lower surface can or be recessed into symbol or alphabetical embossment.
Can be based on the type/model of tablet machine, to desirable those physical propertys of tablet product (for example, desirable hardness, fragility, or the like), desirable tablet appearance and size, or the like, compression stress can be selected.Usually, applied compression power makes the tablet of this compression have the hardness at least about 2kp.These tablets enough hardness and intensity are provided usually and can be packaged, transportation or handled by user.If wish, can be to the higher compression stress of tablet applications to increase tablet hardness.Yet the preferred compression stress of so selecting makes it can not make the granular degeneration that contains activating agent in the tablet (for example, chap or break).Preferably, so applied compression power makes replying less than about 10kp of compressed tablets.In certain embodiments, preferably tablet is compressed to about 3kp to about 7kp, optional about 3kp is to about 5kp, the perhaps hardness of about 3kp.
Usually, the weight of final tablet arrives about 2000mg for about 50mg, and more generally about 200mg is to about 1000mg, and perhaps about 400mg is to about 700mg.
Produce the concrete preparation and the method for the present composition and given unique advantage the sustained release l-arginine compositions.Particularly, preparation of the present invention and method make compositions have desirable sustained-release dissolution scattergram.Randomly, sustained release l-arginine formulations will continue vitro drug release and reach 14 hours at least, discharge about 10% to about 40% in the time of preferred about 1 hour, discharge about 30% to about 70% in the time of about 4 hours, discharge about 55% to about 75% in the time of about 6 hours, discharge about 65% in the time of about 8 hours to about 85%, discharge about 75% in the time of about 12 hours, discharge about 80% to about 100% in the time of about 14 hours to about 95%.As by as illustrated in Fig. 7, preparation of the present invention has been realized this preferred dissolution.In addition, as shown in embodiment 8 and embodiment 14, the dissolving and stability study show preparation of the present invention after production 1 and demonstrated in 2 months the best dissolution profiles figure.
