Sulfasalazine USP
Sulfasalazine USP is a sulfonamide-based anti-inflammatory active pharmaceutical ingredient widely used for the treatment of inflammatory bowel diseases, including ulcerative colitis and Crohn’s disease, as well as rheumatoid arthritis. By inhibiting the production of pro-inflammatory mediators in the intestinal mucosa and modulating immune response, Sulfasalazine USP helps reduce inflammation, control symptoms, and maintain remission. Pharmaceutical companies formulate Sulfasalazine USP into oral tablets and delayed-release formulations, providing consistent dosing for effective management of chronic conditions.
