Treating obesity in patients with cardiovascular disease: the pharmacotherapeutic options

Obesity is a growing health problem that has numerous comorbidities, including cardiovascular disease (CVD). The multi-disciplinary treatment of obesity now includes the use of pharmacotherapy. When treating patients with obesity and CVD, certain medications may be more appropriate than others.

Herein, the authors review the most commonly used FDA approved medications for the treatment of obesity, describing their mechanism of action, and the efficacy and safety of the medications as seen in recent studies, particularly in patients with CVD.

In the population of patients with obesity and CVD, the medications orlistat, lorcaserin and liraglutide are considered the most appropriate options for their treatment, in terms of safety. Sympathomimetic medications, such as phentermine, should be avoided in this group. The recent CAMELLIA-TIMI 61 trial supports the safety of lorcaserin in patients with CVD. Until there are more studies, it is reasonable to extrapolate the findings of the LEADER trial, which found improved CV outcomes in subjects with type 2 diabetes taking liraglutide, to the population of nondiabetic patients being treated for obesity. Further cardiovascular outcomes trials (CVOT) are needed to assess the safety of other pharmacotherapeutic options for weight loss.
