Sulfasalazine (Azulfidine) is an anti-inflammatory agent. It has an immunosuppressive effect, especially in the connective tissue, intestine and serous fluid, where its concentration is the highest. Sulfasalazine is broken down to Sulfapyridine and 5-aminosalicylic acid due to intestinal flora.
Sulfapyridine inhibits the proliferation of killer cells and the transformation of lymphocytes. The anti-inflammatory effect of 5-aminosalicylic acid (mesalazine) is most significant for the treatment of inflammatory diseases of the large intestine.
The drug is effective in the following diseases:
- Acute phase or as maintenance therapy for nonspecific ulcerative colitis and Crohn's disease
- Treatment of rheumatoid and juvenile arthritis

Concomitant use with Sulfasalazine increases the toxicity of Azathioprine and Mercaptopurine.

When concomitant use with Digoxin, its absorption may be reduced; with Talinolol – absorption of Talinolol is reduced; with Folic acid – absorption of Folic acid is reduced.
The dosage is prescribed only by the doctor. Treatment of arthritis consists of gradually increasing the dosage of Sulfasalazine. Sulfasalazine tablets are taken orally, with plenty of water. Drinking tea and other liquids is undesirable. It is also forbidden to break the protective coating of the tablet before use (break or chew the tablet).
