01

What is it?

Linaclotide is an oral peptide that activates guanylate cyclase-C on the intestinal surface, increasing fluid secretion and helping stool move. It treats defined constipation disorders; the eligible age group depends on the diagnosis and current product label. [1]

02

Potential benefits

Increases intestinal fluid secretion and transit. Can improve constipation and abdominal pain in labeled disorders. [1]

03

Evidence & its limits

Diarrhea can be severe. The label contraindicates use in children younger than two because of serious dehydration risk, and in known or suspected mechanical gastrointestinal obstruction. Approval for one constipation diagnosis does not automatically cover another. [1]

04

Risks & unknowns

Diarrhea can be severe. Important pediatric contraindications and warnings apply. [1]

05

Status & scope

Approved human use · product-specific labels. Read the full record for product, formulation and indication-specific status; a biological role or measured response is not a treatment approval. [1]
