Mezavant Xl (Mesalazine)

Mezavant XL, a 5‑ASA derivative, is used in the management of inflammatory bowel disease, specifically ulcerative colitis.

• Ulcerative colitis (induction): achieves remission of active disease.
• Ulcerative colitis (maintenance): helps sustain remission over time.
• Proctosigmoiditis: controls localized colonic inflammation.

• Mesalazine exerts a topical anti‑inflammatory effect within the colon by inhibiting cyclooxygenase and lipoxygenase pathways, scavenging free radicals, and modulating cytokine production, thereby reducing mucosal inflammation and promoting healing of the intestinal lining.

Adverse reactions may occur with mesalazine therapy.
