Pharmacology

The mechanism of action of Mesalamine is unknown, but appears to be topical rather than systemic. Mucosal production of Arachidonic Acid metabolites, both through the cyclooxygenase pathways, that is, prostanoids, and through the lipoxygenase pathways, that is, leukotrienes and hydroxyeicosatetraenoic acids, is increased in patients with chronic infammatory bowel disease. Mesalamine diminishes infammation by blocking cyclooxygenase and inhibiting prostaglandin production in the colon.

Precautions

Patients with pyloric stenosis may have prolonged gastric retention of Mesalamine tablets which could delay release of Mesalamine in the colon. Renal impairment, including minimal change nephropathy and acute and chronic interstitial nephritis has been reported in patients taking Mesalamine. Therefore, caution should be exercised when using Mesalamine in patients with known renal dysfunction or history of renal disease. Patients should have renal function monitored, prior to treatment start and then it should be monitored periodically during treatment. There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered Mesalamine. Caution should be exercised when administering Mesalamine to patients with liver impairment.
