| Common Name | tegaserod |

| Description | Tegaserod belongs to the class of organic compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Tegaserod is a very strong basic compound (based on its pKa). Additionally, tegaserod is a 5-HT2B receptor antagonist. Tegaserod is a 5-HT4 agonist manufactured by Novartis and sold under the names Zelnorm and Zelmac for the management of irritable bowel syndrome and constipation. It also stimulates gastrointestinal motility and the peristaltic reflex, and allegedly reduces abdominal pain. Its use was also approved to treat chronic idiopathic constipation. Novartis alleges all of the affected patients had preexisting cardiovascular disease or risk factors for such, and further alleges that no causal relationship between tegaserod use and cardiovascular events has been demonstrated. The drug functions as a motility stimulant, achieving its desired therapeutic effects through activation of the 5-HT4 receptors of the enteric nervous system in the gastrointestinal tract. In 2019, tegaserod was reintroduced as for use in irritable bowel syndrome with constipation (IBS-C) in women under 65. Before then, it was the only drug approved by the United States Food and Drug Administration to help relieve the abdominal discomfort, bloating, and constipation associated with irritable bowel syndrome. On the same day as the FDA announcement, Novartis Pharmaceuticals Canada announced that it was suspending marketing and sales of the drug in Canada in response to a request from Health Canada. tegaserod is found in Geodia barretti. Currently, tegaserod may only be used in emergency situations only with prior authorization from the FDA. |
