Current trends in the pharmacotherapy for obesity.

Obesity represents a major global challenge from both healthcare and economic perspectives. Although lifestyle modifications aimed at reducing calorie intake and increasing energy expenditure remain the cornerstone of obesity management, pharmacotherapy can serve as a useful adjunct. Until recently, orlistat was the only medication registered for the treatment of obesity in the European Union (EU). A deeper understanding of the complexity of energy homeostasis has resulted in new pharmacological options for weight reduction. In 2015, two new antiobesity drugs were approved in the EU. These are a fixed combination of naltrexone/bupropion (Mysimba®) and liraglutide at a dose of 3.0 mg (Saxenda®). In addition, lorcaserin (Belviq®) and a fixed combination of phentermine/topiramate (Qsymia®) were introduced into the US market in 2012. However, the European Medicines Agency did not approve their use in the EU. The burden of previous weight loss agents that have been withdrawn due to safety concerns underlines the need for caution and close follow-up of patients undergoing pharmacological interventions for obesity treatment. This article provides an overview of the efficacy and safety of currently available weight loss pharmacotherapies.
