- the present invention relates to a process for the preparation of sterilized suspensions to be used in pharmaceutical formulations for inhalation by nebulization, which comprises the following steps: i. filling a tank which has homogenizer with water for injection and wetting the walls of the tank with water for injection. ii. adding the pre-weighed isotonic agent and at least two buffering agents to the water in the tank which has homogenizer, respectively, and mixing at first rotational speed. iii. adding the pre-weighed at least two dispersing or suspending agents to the mixture in the tank which has homogenizer and mixing at a second rotational speed iv. adding the active agent to the mixture in the tank which has homogenizer and mixing at a second rotational speed v.
- mixing, homogenization and autoclaving are carried out in one tank.
- the water for injection in the step numbered (i) is heated to 40- 60° C, more preferably 45-55° C, more preferably 50° C.
- the liquid pharmaceutical composition typically comprises isotonic agents.
- the isotonic agents may be any pharmaceutically acceptable isotonic agents. Suspensions will desirably be isotonic.
- the formulations which are used present process may be adjusted to desired isotonicity by the addition of suitable isotonic agents.
- said isotonic agent in the step numbered (ii) is selected from the group comprising mannitol, sodium chloride, potassium chloride and sodium bromide or a pharmaceutically acceptable salt thereof.
- said isotonic agents in the step numbered (ii) is sodium chloride.
- the liquid pharmaceutical composition comprises one or more buffering agents.
- the buffering agents are pharmaceutically acceptable buffering agents.
- the buffering agents may be any buffering agents suitable for use in a liquid pharmaceutical composition suitable for inhalation.
- One or more buffering agents are typically selected from citrate or phosphate buffers.
- Citrate buffers is selected from the group comprising citric acid, sodium citrate and mixtures thereof.
- Phosphate buffers is selected from the group comprising phosphoric acid, monosodium phosphate, dibasic sodium phosphate and mixtures thereof.
- the pharmaceutical composition comprises at least two buffering agents in the present invention.
- said buffering agents is selected from the group comprising citric acid, sodium citrate, phosphoric acid, monosodium phosphate, dibasic sodium phosphate and mixtures thereof.
- said buffering agents in the step numbered (ii) are monosodium phosphate dihydrate and dibasic sodium phosphate anhydrous.
- Another important factor is the preparation of a suitable dissolution medium by including the dispersing or suspending agents in the process before the active agents to help dissolve the active agents that is insoluble in water.
- said dispersing or suspending agent is selected from the group comprising polysorbate 20 (polyoxyethylene (20) sorbitan monolaurate), polysorbate 40 (polyoxyethylene (20) sorbitan monopalmitate), polysorbate 60 (polyoxyethylene (20) sorbitan monostearate) and polysorbate 80 (polyoxyethylene (20) sorbitan monooleate) sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan tristearate and sorbitan monooleate, sorbitan trioleate (SpanR85), sorbitan mono-oleate, polyoxyethylene (20) sorbitan monooleate, natural lecithin, oleyl polyoxyethylene (2) ether, stearyl polyoxyethylene (2) ether, lauryl polyoxyethylene (4) ether, block copolymers of oxyethylene and oxypropylene, synthetic lecithin, diethylene glycol dioleate, te
- said dispersing or suspending agents in the step numbered (iii) are sorbitan monolaurate and polysorbate 20.
- the active agent is selected glucocorticosteroid or pharmaceutically acceptable salt thereof.
- said glucocorticosteroid is selected from the group comprising ciclesonide, budesonide, fluticasone, aldosterone, beklometazone, betametazone, chloprednol, cortisone, cortivasole, deoxycortone, desonide, desoxymetasone, dexametasone, difluorocortolone, fluchlorolone, flumetasone, flunisolide, fluquinolone, fluquinonide, flurocortisone, fluorocortolone, flurometolone, flurandrenolone, halcynonide, hydrocortisone, icometasone, meprednisone, methylprednisolone, mometasone, paramethasone, prednisolone, prednisone, tixocortole, triamcynolondane or mixtures thereof.
- said glucocorticosteroids is fluticasone.
- said fluticasone salt is fluticasone furoate.
- the rotational speed at which the mixing process takes place is also critical. If a homogeneous mixing cannot be achieved at low rotational speed; the determined mixture uniformity results cannot be achieved. On the other hand, at high rotational speed, the mixture foams and the active agents attach to the foam and collect at the top of the mixture. Thus, the uniformity of mixing will not be achieved again. If the mixture cannot be homogeneous, a suitable product with desired therapeutic properties cannot be produced.
- the steps of adding isotonic agents, buffering agents, dispersing or suspending agents and active agents used in the process to the process and the mixing speed applied are of great importance in order to ensure homogenization and prevent losses in the process.
- the isotonic agent and buffering agents must be mixed at first rotational speed in step numbered (ii).
- said first rotational speed in the step numbered (ii) is 18000- 33600 rpm, preferably 19000-30000 rpm, more preferably 20000-25000 rpm.
- the high rotational speed causes the product to foam. Since the active agents adhere to the foam, the problem of loss of active agents and blend uniformity is observed in the prepared suspension. On the other hand, mixing the active agents at a very low rotational speed causes the problem of blend uniformity. It is therefore a fundamental subject of the present invention to add the mixing speed at different speeds specific to the active agents/isotonic agents/buffering agents/dispersing or suspending agents.
- said second rotational speed in the step numbered (iii) and (iv) is 8800-18000 rpm, preferably 8800-15000 rpm, more preferably 8800-13000 rpm.
- the effect of the final mixing time in the step numbered (iv) on the blend uniformity is great. If the final mixture is mixed for a short time, a homogeneous mixing cannot be achieved and the determined blend uniformity results cannot be achieved. On the other hand, if the final mixture is mixed for a long time; due to the action of the homogenizer, the active agents can be broken and damaged and the particle size can be reduced. In this case, the desired quality target profile cannot be achieved since the active agents targeted to reach the lungs cannot reach the lungs properly.
- the duration of the step number (iv) is 1-15 minutes, preferably 2-13 minutes, more preferably 3-10 minutes.
- said process reduces processing times and gives rise to suspensions with a homogenous, thus producing compositions with a high level of physical stability and therapeutic efficacy.
- autoclaving in the step numbered (v) is at 121 °C for about 15-30 minutes.
- the pharmaceutical compositions subjected to the invention are prepared by these steps: i. filling the tank which has homogenizer with water for injection and wetting the walls of the tank with water for injection ii. adding the pre-weighed sodium chloride, monosodium phosphate dihydrate and dibasic sodium phosphate to the water in the tank which has homogenizer, respectively, and mixing at 18000-33600 rpm, preferably 19000-30000 rpm, more preferably 20000-25000 rpm iii.

People who are suffering from these airway diseases may be treated with medications such as corticosteroids, which are administered via metered-dose inhalers or dry powder inhalers. However, certain patient populations, e.g., neurologically impaired, elderly, or pediatric asthmatics, may lack the breath coordination needed for metered-dose inhalers or lack the lung capacity needed to use DPIs. Thus, these asthma patients require the administration of therapy via nebulizers. One alternative of MDI or DPI is the development of nebulizers in which aqueous solutions of pharmacologically-active substances are sprayed under high pressure so as to produce a mist of inhalable particles.
Drugs combine pharmacologic activity with pharmaceutical properties. Desirable performance characteristics expected from them are physical and chemical stability, ease of processing, accurate and reproducible delivery to the target organ, and availability at the site of action.
Pharmaceutical compositions for inhalation used in the treatment of obstructive respiratory diseases can comprise various active agents such as long acting muscarinic antagonists (LAMA), long acting beta agonists (LABA), short acting beta-2 agonists (SABA) and glucocorti costeroids.
Glucocorticosteroids are a class of drug that lowers inflammation in the body. Inhaled glucocorticosteroids reduce inflammation in the airways that carry air to the lungs (bronchial tubes) and reduce the mucus made by the bronchial tubes which makes easier to breathe.
Among the various types of drug which are administered by inhalation for the treatment of the pulmonary diseases, glucocorticosteroids, such as ciclesonide, budesonide, fluticasone, aldosterone, beklometazone, betametazone, chloprednol, cortisone, cortivasole, deoxycortone, desonide, desoxymetasone, dexametasone, difluorocortolone, fluchlorolone, flumetasone, flunisolide, fluquinolone, fluquinonide, flurocortisone, fluorocortolone, flurometolone, flurandrenolone, halcynonide, hydrocortisone, icometasone, meprednisone, methylprednisolone, mometasone, paramethasone, prednisolone, prednisone, tixocortole, triamcynolondane or mixtures thereof. They are generally administered in suspension, in an aqueous phase that usually also contains one or more pharmaceutically acceptable excipients, such as dispersing and/or suspending agents, isotonic and/or buffering agents, or in a propellant.
Fluticasone is the most commonly used glucocorticosteroid for inhalation. Fluticasone Propionate is the propionate salt form of fluticasone, a synthetic trifluorinated glucocorticoid receptor agonist with antiallergic, anti-inflammatory and antipruritic effects. Fluticasone propionate, sold under the brand name Flixotide, is a steroid medication.
In order to ensure an effective and save penetration into the low respiratory tract of the patient, i.e. bronchioli and alveoli, one of the most important parameters that must be met by pharmaceutical formulations for inhalation is sterility. This requirement is becoming more and more mandatory as confirmed by the FDA final rule "Sterility Requirement for Aqueous-Based Drug Products for Oral Inhalation" published in the Federal Register of May 26, 2000 (65 FR 34082) governing the quality and safety of pharmaceutical products for a number of reasons, including the fact that the lungs are a particularly vulnerable organ of the human body, and many patients who use inhaled drugs have general health problems.
The patent application numbered EP3299013A1 relates to improvements in or relating to pharmaceutical compositions comprising a fluticasone ester. In particular, the invention relates to novel formulations of use in the administration of fluticasone propionate by inhalation.
The patent application numbered EP1494647B1 relates to a process for the preparation of aqueous suspensions of drug particles, to be administered by inhalation, which produces homogenous dispersions of particles characterized by optimal size and size distribution. Also mentioned in the patent document that the active ingredient is homogenized, again under vacuum, using the turbine system and operating at a speed of between 750 and 4000 rpm, preferably between 1000 and 3600 rpm and even more preferably between 1600 and 3000 rpm for 5-60 minutes preferably for 20-40 minutes.
As seen above, there are several processes for producing sterile pharmaceutical formulations for inhalation. However, the stages of adding the excipients and active agents used in the process and the rotation speed applied are of great importance in terms of ensuring homogenization, completing the process in a short time and preventing losses in the process. For example, the high rotational speed causes the product to foam. Since the active agents adhere to the foam, the problem of loss of active agents occurs and poor blend uniformity is observed in the prepared suspension. On the other hand, mixing the active agents at a very low rotational speed causes the problem of blend uniformity.
The steps of adding excipients and active agents used in the process to the process and the rotational speed applied are of great importance in order to ensure homogenization and prevent losses in the process.
On the other hand, these inventions do not include any mention of motivation that excipients or active agents of different properties should be added in a certain order and mixed in the process at different rotational speeds.
Considering the state of art, it can be seen that the prior art has not put enough emphasis on alternative solutions for this problem. Thus, there is still a need for innovative processes that will solve the homogenization problem, and which will provide a standardized method for the fast production of stable homogeneous suspension inhalation compositions with enhanced FPF, delivery rate and total active ingredient values.

According to the preferred embodiment, the active agent is selected glucocorticosteroid or pharmaceutically acceptable salt thereof.
In a preferred embodiment of the invention, said glucocorticosteroid is selected from the group comprising ciclesonide, budesonide, fluticasone, aldosterone, beklometazone, betametazone, chloprednol, cortisone, cortivasole, deoxycortone, desonide, desoxymetasone, dexametasone, difluorocortolone, fluchlorolone, flumetasone, flunisolide, fluquinolone, fluquinonide, flurocortisone, fluorocortolone, flurometolone, flurandrenolone, halcynonide, hydrocortisone, icometasone, meprednisone, methylprednisolone, mometasone, paramethasone, prednisolone, prednisone, tixocortole, triamcynolondane or mixtures thereof.
According to the preferred embodiment, said glucocorticosteroids is fluticasone. According to this preferred embodiment, said fluticasone salt is fluticasone furoate.
The applied process steps have a direct effect on the blend uniformity, which is one of the first chemical indicators of the product's quality profile. It has been observed that if the above steps are not followed in the present process, the blend uniformity cannot be achieved.
In the invention, the rotational speed at which the mixing process takes place is also critical. If a homogeneous mixing cannot be achieved at low rotational speed; the determined mixture uniformity results cannot be achieved. On the other hand, at high rotational speed, the mixture foams and the active agents attach to the foam and collect at the top of the mixture. Thus, the uniformity of mixing will not be achieved again. If the mixture cannot be homogeneous, a suitable product with desired therapeutic properties cannot be produced.
The steps of adding isotonic agents, buffering agents, dispersing or suspending agents and active agents used in the process to the process and the mixing speed applied are of great importance in order to ensure homogenization and prevent losses in the process.
According to the invention, the isotonic agent and buffering agents must be mixed at first rotational speed in step numbered (ii).
According to one embodiment, said first rotational speed in the step numbered (ii) is 18000- 33600 rpm, preferably 19000-30000 rpm, more preferably 20000-25000 rpm.
During the addition of dispersing or suspending agents and active agents, the high rotational speed causes the product to foam. Since the active agents adhere to the foam, the problem of loss of active agents and blend uniformity is observed in the prepared suspension. On the other hand, mixing the active agents at a very low rotational speed causes the problem of blend uniformity. It is therefore a fundamental subject of the present invention to add the mixing speed at different speeds specific to the active agents/isotonic agents/buffering agents/dispersing or suspending agents.
According to one embodiment, said second rotational speed in the step numbered (iii) and (iv) is 8800-18000 rpm, preferably 8800-15000 rpm, more preferably 8800-13000 rpm.
The effect of the final mixing time in the step numbered (iv) on the blend uniformity is great. If the final mixture is mixed for a short time, a homogeneous mixing cannot be achieved and the determined blend uniformity results cannot be achieved. On the other hand, if the final mixture is mixed for a long time; due to the action of the homogenizer, the active agents can be broken and damaged and the particle size can be reduced. In this case, the desired quality target
profile cannot be achieved since the active agents targeted to reach the lungs cannot reach the lungs properly.
According to one embodiment, the duration of the step number (iv) is 1-15 minutes, preferably 2-13 minutes, more preferably 3-10 minutes.
According to one embodiment, said process reduces processing times and gives rise to suspensions with a homogenous, thus producing compositions with a high level of physical stability and therapeutic efficacy.
In an embodiment, autoclaving in the step numbered (v) is at 121 °C for about 15-30 minutes.
According to one embodiment, the pharmaceutical compositions subjected to the invention are prepared by these steps: i. filling the tank which has homogenizer with water for injection and wetting the walls of the tank with water for injection ii. adding the pre-weighed sodium chloride, monosodium phosphate dihydrate and dibasic sodium phosphate to the water in the tank which has homogenizer, respectively, and mixing at 18000-33600 rpm, preferably 19000-30000 rpm, more preferably 20000-25000 rpm iii. adding the pre-weighed polysorbate 20 (Tween 20) and sorbitan monolaurate (Span 20) to the mixture in the tank which has homogenizer and mixing at 8800-18000 rpm, preferably 8800-15000 rpm, more preferably 8800-13000 rpm iv. adding the active agent to the mixture in the tank which has homogenizer and mixing at 8800-18000 rpm, preferably 8800-15000 rpm, more preferably 8800-13000 rpm v. autoclaving the product in the tank which has homogenizer vi. filling the autoclaved product into nebul vials wherein said first rotational speed in the step numbered (ii) is 18000-33600 rpm and said second rotational speed in the step numbered (iii) and (iv) is 8800-18000 rpm.
