Linaclotide and its active metabolite bind and agonize guanylate cyclase-C on the luminal surface of intestinal epithelium. Intracellular and extracellular cyclic guanosine monophosphate (cGMP) concentrations are subsequently increased resulting in chloride and bicarbonate secretion into the intestinal lumen. Intestinal fluid increases and GI transit is accelerated. Increased extracellular cGMP may decrease visceral pain by reducing pain-sensing nerve activity.
