Sulfasalazine is an anti-inflammatory and immunomodulatory medication used primarily in the treatment of ulcerative colitis, Crohn’s disease, and rheumatoid arthritis. It consists of two pharmacologically active components—5-aminosalicylic acid (5-ASA) and sulfapyridine—joined by an azo bond that breaks down in the intestine to release both agents. Salius Pharma supplies high-quality Sulfasalazine API as an orange-yellow crystalline powder, compliant with IP, BP, and USP pharmacopeial requirements.
Inside the colon, intestinal bacteria break the azo bond of Sulfasalazine into: 5-ASA (Mesalamine): anti-inflammatory effect on the gut; Sulfapyridine: systemic immunomodulatory activity. Together, these actions reduce inflammation, suppress immune overactivity, and improve gastrointestinal symptoms.
