BOXED WARNING
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 is an immunosuppressive antimetabolite. Each uncoated
azathioprine tablet
intended for oral administration contains 50 mg of azathioprine. In
addition, each tablet
contains the following inactive ingredients: croscarmellose sodium,
lactose
monohydrate, magnesium stearate, povidone and starch.
Azathioprine is chemically
6-[(1-methyl-4-nitro-_1H_-imidazol-5-yl)thio]-_1H_-purine. 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 a pale yellow, odorless powder. It is insoluble
in water, soluble in
dilute solutions of alkali hydroxides, sparingly soluble in dilute
mineral acids, very slightly
soluble in alcohol and in chloroform. The sodium salt of azathioprine
is sufficiently
soluble to make a 10 mg/mL water solution which is stable for 24 hours
at 59° to 77°F
(15° to 25°C). Azathioprine 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
