Mechanism of action

By activating GC-C receptors on the apical surface of intestinal epithelial cells, linaclotide increases cGMP levels, which opens cystic fibrosis transmembrane conductance regulator (CFTR) chloride channels and promotes water secretion into the intestinal lumen. This increases stool frequency and softens stool consistency, providing relief from constipation and associated abdominal discomfort.
