Randomized Controlled Trial Multicenter Study
Linaclotide improves abdominal pain and bowel habits in a phase IIb study of patients with irritable bowel syndrome with constipation.
Linaclotide, a minimally absorbed, 14-amino acid peptide agonist of guanylate cyclase-C, has shown benefit in a proof-of-concept study for the treatment of patients with irritable bowel syndrome (IBS) with constipation (IBS-C). We assessed the efficacy and safety of linaclotide at a daily dose range of 75-600 μg in IBS-C. ⋯ Linaclotide, across a wide range of doses, significantly improved symptoms of IBS-C, including abdominal pain and bowel symptoms. Diarrhea was the only dose-dependent adverse event and was usually of mild or moderate severity.
