Description

Biochem/physiol Actions

Linaclotide is an orally active guanylate cyclase-C (GC-C) agonist that competes against bacterial STa enterotoxin binding to intestinal mucosal membranes from wild-type, but not GC-C null, mice (Ki = 16.4 nM). Linaclotide stimulates fluid secretion, upregulates cGMP accumulation in the intestinal lumen (5 μg/100 μL via injection into surgically ligated intestinal loops), and significantly increases the rate of gastrointestinal transit when administered orally in mice in vivo (100 μg/kg p.o.).

Orally active guanylate cyclase-C (GC-C) agonist that elicits in vivo pharmacological effects locally in the gastrointestinal tract.
