Ipamorelin(CAT: M038637), also known as NNC-26-0161, is a ghrelin mimetic. Ipamorelin counteracts the glucocorticoid-induced decrease in bone formation in adult rats. Ipamorelin may ameliorate the symptoms in patients with POI. Ipamorelin accelerates gastric emptying in a rodent model of postoperative ileus through the stimulation of gastric contractility by activating a ghrelin receptor-mediated mechanism involving cholinergic excitatory neurons. This product is used in medical research and development and other scientific research fields.
