Tegaserod（Cat No.:M104362）is a selective serotonin 5-HT₄ receptor partial agonist that enhances gastrointestinal motility by stimulating peristalsis and accelerating intestinal transit. It also modulates visceral sensitivity, reducing abdominal discomfort. Clinically, tegaserod has been used for the short-term treatment of irritable bowel syndrome with constipation (IBS-C) in women and for chronic idiopathic constipation. By activating 5-HT₄ receptors in the enteric nervous system, it increases acetylcholine release, promoting coordinated bowel movements. With a well-characterized safety and efficacy profile, tegaserod remains a valuable agent for studying serotonergic regulation of gut function and motility disorders.
