Which sulfonamide is a prodrug used in the treatment of inflammatory bowel disease (IBD) like Ulcerative Colitis?

  1. Sulfacetamide
  2. Sulfamethoxazole
  3. Sulfadoxine
  4. Sulfasalazine
Show answer and explanation

Correct answer: Sulfasalazine

Sulfasalazine is poorly absorbed in the small intestine. In the colon, bacterial enzymes break the azo bond to release sulfapyridine and 5-aminosalicylic acid (mesalamine), the latter of which provides the local anti-inflammatory effect.
