PRESCRIPTION DRUG
Azathioprine tablets are indicated as an adjunct for the prevention of rejection in renal homotransplantation. It is also indicated for the management of active rheumatoid arthritis to reduce signs and symptoms. Renal Homotransplantation: Azathioprine tablets are indicated as an adjunct for the prevention of rejection in renal homotransplantation. Experience with over 16,000 transplants shows a 5-year patient survival of 35% to 55%, but this is dependent on donor, match for HLA antigens, anti-donor or anti-B-cell alloantigen antibody, and other variables. The effect of azathioprine on these variables has not been tested in controlled trials. Rheumatoid Arthritis: Azathioprine tablets are indicated for the treatment of active rheumatoid arthritis (RA) to reduce signs and symptoms. Aspirin, non-steroidal anti-inflammatory drugs and/or low dose glucocorticoids may be continued during treatment with azathioprine. The combined use of azathioprine with disease modifying anti-rheumatic drugs (DMARDs) has not been studied for either added benefit or unexpected adverse effects. The use of azathioprine tablets with these agents cannot be recommended. Azathioprine tablets should not be given to patients who have shown hypersensitivity to the drug. Azathioprine tablets should not be used for treating rheumatoid arthritis in pregnant women. Patients with rheumatoid arthritis previously treated with alkylating agents (cyclophosphamide, chlorambucil, melphalan, or others) may have a prohibitive risk of malignancy if treated with azathioprine tablets.

Abbreviated New Drug Application
AZATHIOPRINE- AZATHIOPRINE TABLET AMNEAL PHARMACEUTICALS NY LLC ---------- AZATHIOPRINE TABLETS, USP (50 MG, 75 MG AND 100 MG) RX ONLY WARNING - MALIGNANCY CHRONIC IMMUNOSUPPRESSION WITH AZATHIOPRINE, A PURINE ANTIMETABOLITE INCREASES _RISK OF MALIGNANCY_ IN HUMANS. REPORTS OF MALIGNANCY INCLUDE POST-TRANSPLANT LYMPHOMA AND HEPATOSPLENIC T-CELL LYMPHOMA (HSTCL) IN PATIENTS WITH INFLAMMATORY BOWEL DISEASE. PHYSICIANS USING THIS DRUG SHOULD BE VERY FAMILIAR WITH THIS RISK AS WELL AS WITH THE MUTAGENIC POTENTIAL TO BOTH MEN AND WOMEN AND WITH POSSIBLE HEMATOLOGIC TOXICITIES. PHYSICIANS SHOULD INFORM PATIENTS OF THE RISK OF MALIGNANCY WITH AZATHIOPRINE (SEE WARNINGS). DESCRIPTION Azathioprine, an immunosuppressive antimetabolite, is available in tablet form for oral administration. Each scored tablet contains 50 mg, 75 mg or 100 mg azathioprine, USP and the inactive ingredients anhydrous lactose, magnesium stearate, povidone, pregelatinized starch (corn starch), and stearic acid. Azathioprine is chemically 1_H_-Purine, 6-[(1-methyl-4-nitro-1_H_-imidazol-5-yl)thio]-. The structural formula of azathioprine is: It is an imidazolyl derivative of 6-mercaptopurine and many of its biological effects are similar to those of the parent compound. Azathioprine, USP is insoluble in water, but may be dissolved with addition of one molar equivalent of alkali. Azathioprine, USP is stable in solution at neutral or acid pH but hydrolysis to mercaptopurine occurs in excess sodium hydroxide (0.1N), especially on warming. Conversion to mercaptopurine also occurs in the presence of sulfhydryl compounds such as cysteine, glutathione and hydrogen sulfide. CLINICAL PHARMACOLOGY Azathioprine is well absorbed following oral administration. Maximum serum radioactivity occurs at 1 to 2 hours after oral S-azathioprine and decays with a half-life of 5 hours. This is not an estimate of the half-life of azathioprine itself, but is the decay rate for all S-containing metabolites of the drug. Because of extensive metabolism, only a fraction of the ra Läs hela dokumentet
