Qysmia

the Food and Drug Administration (FDA) approved Qsymia, the second new diet drug in a month, and the most effective of the weight-loss pills that the agency has considered in recent years.

 

Diet pills have had a spotty history with the FDA, largely because of safety problems involving the heart. Other drugs — most notably fenfluramine, used in the popular weight-loss combination fen-phen — have been withdrawn from the market for such hazards, and new drugs have had to clear a high bar for consideration.
