• Description: In June 2012, the US FDA approved lorcaserin for chronic weight management in adult patients who are characterized as overweight or obese and have at least one comorbid, weight-related condition. Lorcaserin (also known as APD356) is the first 5-HT2C agonist approved for chronic weight management since the withdrawal of the 5-HT2C agonist fenfluramine in 1997 due to rare cases of cardiac valvulopathy. The serotonin receptor 5-HT2C is found primarily in the hypothalamus and regulates appetite and feeding behavior. Safety issues with fenfluramine were associated with poor selectivity for 5-HT2C versus 5HT2A and 5HT2B. Ring constraint afforded by the benzazepine in lorcaserin improved selectivity for 5HT2C by over 2 log units. Lorcaserin (hydrochloride) (CRM) (Item No. 19247) is a certified reference material categorized as an anorectic. It also decreases oxycodone intake and has positive effects on self-administration and relapse vulnerability in the rat. Lorcaserin is regulated as a Schedule IV compound in the United States. This product is intended for research and forensic applications.
• Uses: Lorcaserin hydrochloride, a novel antiobesity drug, is a selective serotonin 5-HT2C receptor agonist, approved by FDA in 2012.
