  • Title: Evaluation of lorcaserin for the treatment of obesity.
    Author: Berlie HD, Hurren KM.
    Journal: Expert Opin Drug Metab Toxicol; 2013 Aug; 9(8):1053-9. PubMed ID: 23802690.
    Abstract:
    INTRODUCTION: Obesity is an epidemic associated with significant morbidity. Lorcaserin , a novel serotonin 2C receptor antagonist, was recently approved as an adjunct to lifestyle modification for long-term weight loss and maintenance. Clinical studies in patients without diabetes demonstrated 5.8% mean weight loss from baseline with lorcaserin compared to 2.5% with placebo and over twice as many patients achieved ≥ 5% weight loss. Patients with diabetes achieved mean weight loss of 4.5% with lorcaserin compared to 1.5% with placebo as well as modest improvements in glycemic outcomes. AREAS COVERED: The authors review the pharmacology and clinical efficacy as well as the safety and tolerability of lorcaserin. This was achieved through a PubMed search (1960 - present) on lorcaserin to generate the key literature in the area. The lorcaserin package insert and Food and Drug Administration briefing documents were also used to identify relevant information. To assess long-term clinical efficacy and safety, the authors used studies with a minimum duration of one year. EXPERT OPINION: Lorcaserin induces moderate but significant weight loss compared to placebo as an adjunct to lifestyle modification. Although head-to-head comparison trials are not available, lorcaserin is likely less effective but better tolerated than its recently approved competitor, phentermine/topiramate. Cardiovascular outcome data will be invaluable in determining lorcaserin's eventual utilization and place in therapy.
