Belviq (generic name- lorcaserin) is the new kid on the block when it comes to weight loss, and it’s the first weight loss drug to gain approval in 13 years. The drug works by activating a brain receptor that makes an individual feel full and, as with most weight loss drugs, is supposed to be used in conjunction with a reduced-calorie diet and regular exercise.

Despite being touted for its potential to curb the obesity epidemic, the FDA rejected Contrave back in February due to safety concerns. The company actually put some of the blame on the FDA, saying that they were requiring “unprecedented” safety studies. However, the FDA has now outlined a clinical trial that could be completed by 2014 and would allow any significant side effects to come to light. And if the study goes well, it could be the first weight loss drug approved in the US in more than a decade.
