Azulfidine RA

Azulfidine RA Uses, Dosage, Side Effects, Food Interaction and all others data.

The mode of action of Azulfidine RA is still under investigation, but 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 Azulfidine RA, Sulfapyridine and 5-Aminosalyclic Acid have indicated that the major therapeutic action may reside in the 5-Aminosalyclic Acid moiety. The relative contribution of the parent drug and the major metabolites in rheumatoid arthritis is unknown.

Azulfidine RA is an anti-inflammatory indicated for the treatment of ulcerative colitis and rheumatoid arthritis.

How Azulfidine RA works

The mode of action of Azulfidine RA or its metabolites, 5-aminosalicylic acid (5-ASA) and sulfapyridine (SP), is still under investigation, but 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 Azulfidine RA, 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.
