A double‐blind comparison of balsalazide, 6.75 g, and sulfasalazine, 3 g, as sole therapy in the management of ulcerative colitis

Sulfasalazine is accepted therapy for active ulcerative colitis, but side‐effects and intolerance are common. Balsalazide is an azo‐bonded pro‐drug which also releases 5‐aminosalicylic acid into the colon, but uses an inert carrier molecule.
