Page 1 of 11 PRODUCT INFORMATION IMAZAN 25 MG & 50 MG TABLETS NAME OF THE MEDICINE The active ingredient in IMAZAN is azathioprine. Chemical structure: _ _ Chemical formula:C 9 H 7 N 7 O 2 S CAS no.: 446-86-6 Chemical name: 6-[(1-methyl-4-nitro-1_H_-imidazol-5-yl)thio]-7_H_-purine. Molecular weight: 277.3. DESCRIPTION Azathioprine is a pale yellow powder. It is practically insoluble in water or ethanol (96%). It is soluble in dilute solutions of alkali hydroxides and sparingly soluble in dilute mineral acids. IMAZAN tablets also contain the following ingredients: microcrystalline cellulose, croscarmellose sodium, mannitol, povidone, sodium stearylfumarate, maize starch and 25 mg only: Opadry Buff OY-3682, Opadry Buff OY-3690 and Opadry OY-1315G. 50 mg only: Opadry clear OY-7240. PHARMACOLOGY Azathioprine is an imidazole derivative of 6-mercaptopurine (6-MP). It is rapidly broken down _in-vivo _into 6-MP and a methylnitro-imidazole moiety. The 6-MP readily crosses cell membranes and is converted intracellularly into a number of purine thioanalogues, which include the main active nucleotide, thioinosinic acid. The rate of conversion varies from one person to another. Nucleotides do not transverse cell membranes and therefore do not circulate in body fluids. Irrespective of whether it is given directly or is derived _in-vivo _from azathioprine, 6-MP is eliminated mainly as the inactive oxidised metabolite thiouric acid. This oxidation is brought about by xanthine oxidase, an enzyme that is inhibited by allopurinol. The activity of the methylnitroimidazole moiety has not been defined clearly. However, in Page 2 of 11 several systems it appears to modify the activity of azathioprine as compared with that of 6-MP. The determination of azathioprine or 6-MP plasma concentrations has no prognostic value as regards effectiveness or toxicity of these compounds. While the precise mode of action remains to be elucidated, some suggested mechanisms include: The release of 6-MP which acts as a purine antimetabolite; The Կարդացեք ամբողջական փաստաթուղթը
