Mesalazine is considered to be the active moiety of sulfasalazine. The mechanism of action is uncertain, but may be due to its ability to inhibit local chemical mediators of the inflammatory response especially leukotriene synthesis in the GI mucosa. Action may be topical in terminal ileum and colon rather than systemic.
Do not give with lactulose or other drugs which lower pH for they prevent release of mesalazine. May decrease digoxin absorption.
