What to Expect
A peptide guanylate cyclase-C agonist for IBS-C and chronic constipation. Works locally in the gut with minimal systemic absorption.
Mechanism of Action
Linaclotide activates guanylate cyclase-C on intestinal epithelium, increasing cGMP which leads to chloride and water secretion into the intestines. Also reduces visceral pain signaling.
Research Summary
Multiple trials showed improvement in bowel movements and abdominal pain in IBS-C. Works within the first week. Also effective for chronic idiopathic constipation.
