סממני תרפויטית:

AZULFIDINE EN-tabs Tablets are indicated: AZULFIDINE EN-tabs is particularly indicated in patients with ulcerative colitis who cannot take uncoated sulfasalazine tablets because of gastrointestinal intolerance, and in whom there is evidence that this intolerance is not primarily the result of high blood levels of sulfapyridine and its metabolites, e.g., patients experiencing nausea and vomiting with the first few doses of the drug, or patients in whom a reduction in dosage does not alleviate the adverse gastrointestinal effects. In patients with rheumatoid arthritis or juvenile rheumatoid arthritis, rest and physiotherapy as indicated should be continued. Unlike anti-inflammatory drugs, AZULFIDINE EN-tabs does not produce an immediate response. Concurrent treatment with analgesics and/or nonsteroidal anti-inflammatory drugs is recommended at least until the effect of AZULFIDINE EN-tabs is apparent. AZULFIDINE EN-tabs Tablets are contraindicated in: Hypersensitivity to sulfasalazine, its metabolites, sulfonam

CLINICAL PHARMACOLOGY
PHARMACODYNAMICS
The mode of action of sulfasalazine (SSZ) or its metabolites,
5-aminosalicylic acid (5-
ASA) and sulfapyridine (SP), may be related to the anti-inflammatory
and/or
immunomodulatory properties that have been observed in animal and in
vitro models, to
its affinity for connective tissue, and/or to the relatively high
concentration it reaches in
serous fluids, the liver and intestinal walls, as demonstrated in
autoradiographic studies
in animals. In ulcerative colitis, clinical studies utilizing rectal
administration of SSZ, SP
and 5-ASA have indicated that the major therapeutic action may reside
in the 5-ASA
moiety. The relative contribution of the parent drug and the major
metabolites in

rheumatoid arthritis is unknown.
PHARMACOKINETICS
In vivo studies have indicated that the absolute bioavailability of
orally administered SSZ
is less than 15% for parent drug. In the intestine, SSZ is metabolized
by intestinal
bacteria to SP and 5-ASA. Of the two species, SP is relatively well
absorbed from the
intestine and highly metabolized, while 5
