Definitions
- the present invention relates to azodicarbonamide
- ADA Azodicarbonamide
- ADA also means each of the cis and trans isomers of this substance as well as their racemic mixture.
- This material has been used as a blowing agent in the rubber and plastics industry. At a temperature of about 190-230O azodicarbonamide is decomposed into gases (nitrogen, carbon monoxide, carbon dioxide and ammonia), solid residues and sublimed substances. It has also been used to improve flour in bakery.
- ADA also has a therapeutic effect against various diseases, in particular viral infections, certain cancerous diseases and disorders resulting from the pathological production of cytokines (see EP-B).
- a Celogen® AZ-2990 product is known which is marketed by the firm Uniroyal. This product is a mixture of micronised ADA and an inert flow conditioner, which makes this product contraindicated in pharmaceutical use. If the nominal particle size of this mixture is indicated at 2-2.4 microns, the particle size distribution of the product is not known.
- US-2005/0222281 A1 discusses the possibility of producing micronized ADA using an air jet disintegrator. This document discourages such a process because it notes that, on the one hand, if it were to be implemented, theoretically it would be economically unprofitable because demanding a huge expenditure of energy and that, on the other hand, the powders as well obtained would have a wide particle size distribution, leading to large flow problems for the resulting powder. Processes for producing very pure ADA have been known for a long time, and even methods for achieving particle sizes at the micron scale (see for example GB-1-181729).
- the micronization obtained is insufficient because the particle size distribution of the particles is very wide which affects the reproducibility of the results that could be obtained with this product, if it was applied for example in pharmacy.
- 01/03670 a micronization of ADA in aqueous dispersion medium was revealed that it gives little advantage because it gives rise to a foam which remains stable for several weeks. Also, it is recommended in this document to proceed rather to micronization in a non-aqueous liquid medium, under high pressure (500-700 bar).
- non-aqueous is meant in WO-01/03670 an organic liquid, for example polyethylene glycol 400, to which is added, to improve the dispersion, a surfactant such as Tween 80.
- ADA having a d 50 of 3.0 ⁇ m to 5.5 ⁇ m, some of which particles can reach up to more than 7.0 ⁇ m.
- This product contains of course still traces of the dispersion medium.
- Polyethylene glycol is a pharmaceutically toxic substance that must be removed by degassing at elevated temperature.
- the ADA produced according to the state of the art is in the form of very hard crystals that are difficult to micronize, while avoiding during micronization degradation of the ADA and after micronization a reagglomeration of particles fine micronized. So far, it has been planned to obviate these drawbacks unsatisfactory micronization in a humid medium or an addition to the ADA micronized surfactants or a coating of ADA particles, rendering the product unusable in pharmacy.
- the present invention aims to solve the problems posed by providing a good azodicarbonamide - A - bioavailability properties, which, at therapeutically active dosages, have drastically reduced, if not zero, toxicity.
- the particle size of the ADA must be as little variable as possible, during storage.
- azodicarbonamide in the form of a micronized dry powder, which is characterized in that the said powder has a particle size distribution of particles in which the particles of the powder exhibit a average diameter (d 5 o) equal to or less than 2 ⁇ m, preferably equal to or less than 1.8 ⁇ m, advantageously of the order of 1, 5-1, 6 ⁇ m.
- the particles of the powder also have a diameter of 90% (d 90 ) equal to or less than 4 ⁇ m, advantageously of the order of 3.4 to 3.9 ⁇ m.
- the ADA has a degree of pharmaceutical purity, in particular greater than 98%, especially greater than 98.4%.
- the ADA particles are not coated.
- the micronized ADA particles according to the invention have a diameter of 10% ( ⁇ h) equal to or less than 0.6 ⁇ m.
- micronized particles having a size less than a value of 5 ⁇ m.
- Such a process has the advantage of not diluting or contaminating the ADA in other substances subsequently undesirable and to proceed to moderate pressures and temperatures that are not likely to alter the ADA.
- the step of producing the azodicarbonamide is carried out under conditions of pressure and temperature that are ambient or close to these.
- the drying of the ADA produced takes place under moderate pressure and temperature conditions, for example ambient conditions.
- the pressure in the air jet disintegrator is less than 100 bar, preferably less than 75 bar, in particular of the order of 60 bar.
- the disintegration in an air jet occurs at a temperature below the decomposition temperature of the ADA (190-230O), preferably at room temperature. The micronized ADA thus undergoes no or little alteration during the decay and, as will be seen later, it has been possible to observe the formation of a powder whose particle size remains stable for very long periods of time , additives free.
- the present invention also relates to a pharmaceutical composition containing, as active substance, ADA in the form of a micronized dry powder according to the invention.
- These compositions may contain a pharmaceutically compatible excipient and one or more adjuvants common in pharmacy.
- compositions according to the invention containing ADA and at least one other therapeutically active substance in combination, such as for example AZT, ritonavir, T-20, or the like.
- Such a composition may for example be in the form of a powder, a tablet, a pill, a capsule, a capsule, a dragee, a suspension, a cream , a paste, a syrup or sachets.
- the composition may be administered in a routine manner, for example orally, sublingually, rectally, vaginally, locally, transcutaneously or transmucosally or by injection or infusion.
- the present invention also relates to a process for the preparation of a pharmaceutical composition as indicated above, this process comprising a combination of ADA according to the invention and a pharmaceutically compatible excipient, as well as any adjuvants. currents.
- the present invention also relates to a use of ADA according to the invention for the manufacture of a medicament for use in the treatment of viral diseases, in particular infections with viruses containing a protein called "zinc finger".
- ADA a protein called "zinc finger”.
- the treatment of human or animal infections by papillomaviruses, retroviruses, in particular human immunodeficiency virus, arenaviruses, herpesviruses, hepatitis C virus is contemplated.
- ADA for the manufacture of a medicament for use in the treatment of human or animal diseases resulting from the pathological production of cytokines or lymphokines as well as for the manufacture of a medicament for use in works in the treatment of human or animal diseases giving rise to a production important and pathological cell of deoxyribonucleic acid, of the cancerous type.
- the present invention also relates to a use of ADA according to the invention or of a pharmaceutical composition containing ADA according to the invention for the treatment of cells of microorganisms, isolated cells, macroorganisms and cells of an organism or cellular tissue extracted from a human or animal body, particularly a transplant.
- biurea also called hydrazodicarbonamide.
- Water is used as the solvent.
- the biurea is then precipitated, filtered and washed with water.
- the biurea is then suspended in water and chlorine gas or hydrogen peroxide is bubbled into this medium, optionally in the presence of an inert gas, such as air, nitrogen or carbon dioxide.
- an inert gas such as air, nitrogen or carbon dioxide.
- carbon dioxide which causes an oxidation of the biurea with formation of a double bond between the central nitrogens, giving azodicarbonamide.
- This product is then filtered, washed with water to conditions close to neutrality and dried at a temperature close to room temperature, preferably to the latter.
- Azodicarbonamide is sensitive to high pressures and temperatures because it then forms by-products such as semicarbazide, hydrazine, and / or biurea and the formed ADA crystals are characterized by exceptional hardness. With the aid of an HPLC method, it has been possible to determine the production of azodicarbonamide prepared according to the process of this example at a purity level greater than 98%, especially 98.4%, ie say the pharmaceutical quality.
- This device comprises a cylindrical grinding chamber, conical bottom which is made of stainless steel covered with an elastomer.
- the diameter of the chamber is 100 mm and volume of 800 cm 3.
- the particles to be disintegrated are introduced into the chamber by an endless screw.
- the particles are then thrown against each other by jets of compressed air with 3 air lances with a diameter of 2 mm which meet at the same point.
- the air stream formed then carries the disintegrated particles at 50 bar to a turbo-selector which is integrated in the grinding chamber.
- This turbo-breeder has in this example the form of a squirrel cage which has a rotational speed adjustable from 5,000 to 16,000 revolutions per minute.
- This device allows the exit of smaller particles of a given size, in this case ⁇ 5 microns, and pushes in the grinding chamber particles of a larger size.
- the fine particles (desired size) leaving the grinding chamber are collected and collected for example using a cyclone.
- the air is filtered before it returns to the atmosphere. It appeared that using such a device it was possible at a moderate pressure of the order of 75 bars to the inlet and 50 bars inside micronize the ADA in a single 3-hour cycle.
- mice are randomly divided into 9 groups of 6 animals and receive a dose of ADA by gavage.
- Group A receives 10 mg / kg body weight of micronized ADA according to the invention (suspended in carboxymethylcellulose (CMC)).
- CMC carboxymethylcellulose
- Group B receives 10 mg / kg of non-micronized ADA (suspended in CMC).
- Group C receives 10 mg / kg of ADA dissolved in dimethylsulfoxide (DMSO).
- DMSO dimethylsulfoxide
- Group D receives 5 mg / kg of micronized ADA according to the invention (in suspension in CMC).
- Group E receives 5 mg / kg of non-micronized ADA (suspended in CMC).
- Group F receives 5 mg / kg of ADA dissolved in DMSO.
- Group G receives 1.25 mg / kg of micronized ADA according to the invention (in suspension in CMC).
- Group H receives 1.25 mg / kg of non-micronized ADA (suspended in CMC).
- Group I receives 1.25 mg / kg of ADA in solution in DMSO.
- FIG. 1 represents a histogram in which the values on the abscissa are the ADA dosages administered in mg per kg of body weight and the values on the ordinate the biowea concentrations in ⁇ g / ml in the blood plasma.
- the groups which received the micronized ADA according to the invention have at all dosages a bioavailability of ADA in the blood significantly better than non-micronized ADA.
- the ADA according to the invention has even better bioavailability than fully dissolved ADA.
- azodicarbonamide administered orally The toxicity of azodicarbonamide administered orally is examined. It is known that, during the administration of ADA as commercially available, having a d 5 o of 18 ⁇ m and a d 90 of ⁇ 35 ⁇ m, the formation of biuric crystals is rapidly observed in the urine. .
- Rats which were orally dosed daily for 28 days with 900, 150 and 25 mg of ADA according to the invention / kg of body weight were tested.
- the ADA was in the form of a micronized powder according to the invention in suspension in carboxymethylcellulose.
- an identical test was performed on dogs at daily doses for 28 days of 400, 100 and 25 mg of ADA according to the invention / kg of body weight. In neither of the two tests could adverse effects be observed.
- ESD free gelatin-coated capsules containing a composition as described in Example 4 were administered for 7 days to healthy male volunteers at a dosage of up to 6 g per day ( single dose of 150 to 6000 mg and repeated doses of 300 to 2400 mg).
- Urine examination was performed using flow cytometry (detection limit 2 ⁇ m). Urinary stones or stones could not be observed.
- micronized ADA according to the invention is administered to the rats by gavage in the form of a suspension in poloxamer 188.
- the administration takes place twice a day in dosages of 125 and 250 mg / kg. , from day -1 until day 20. It has been observed that this treatment with ADA gives rise to a significant inhibition of the increase obtained for the control animals of the reactivity of the respiratory tract with interleukins, at all doses of metacholine induced by antigenic attack in animals sensitized as described above.
- This composition contains 50 mg of azodicarbonamide according to the invention as well as wax of cetyl esters, cetyl alcohol, white wax, glyceryl monostearate, propylene glycol monostearate, methyl stearate, sodium lauryl sulphate, glycerin, mineral oil and benzyl alcohol as a preservative.
- Example 10 This microbicidal and virucidal composition can be useful for local and preventive use.
- Example 10 This microbicidal and virucidal composition can be useful for local and preventive use.
- the active substance was then incorporated into capsules which were stored in a refrigerator at 8 ° C for 11 months to determine the stability of the ADA according to the standards (International Harmonization Conference, ICH).
- the size of the ADA particles was again determined at this time as well as after an additional 3 months of incubation at 25 ° / 60% humidity.
