F.D.A. Rejects Qnexa, a Third Weight-Loss Drug
New York Times

The Food and Drug Administration rejected another new diet pill on Thursday, the latest setback in the quest to develop treatments for overweight Americans amid the nation’s obesity epidemic. The rejected drug, called Qnexa, is the third weight loss medicine to run into trouble this month because of concerns about safety. Last week, the F.D.A. declined to approve another new drug, lorcaserin, because it caused tumors in rats. And earlier in the month it forced the withdrawal of Meridia from the market after 13 years, citing the risk of heart attacks and strokes for certain patients.
