Linaclotide

What it's for

Linaclotide is a minimally absorbed 14–amino-acid peptide medicine that turns on guanylate cyclase-C on the lining of the intestine. It is used for irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in adults (and labeled pediatric groups where applicable).

What it does for the body

It treats irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC) in adults (and labeled pediatric populations where applicable). People often hear about it through clinics, forums, or news — this guide sticks to what published research and regulators actually support.

What it targets

GC-C activation raises cGMP (a messenger that helps blood vessels relax), increasing chloride and bicarbonate secretion via CFTR, accelerating transit and reducing visceral pain signaling. Think of pain signals as messages traveling a wire; this medicine can quiet the gates that let those messages through near the spinal cord.

Research context

Bottom line for readers: Linaclotide has a defined FDA-approved story. Use the citations tab to open labels and trial registries, and treat anything beyond the label as unverified.
