FDA Rejects Diet Pill Qnexa

Qnexa, what would have been the first new weight loss drug in a decade, was rejected in a narrow vote by the Food and Drug Administration. They reported concerns about the lack of data about the pill’s cardiovascular effects. The committee voted 10-6 against Qnexa, created by Vivus, Inc., which contains one of the active ingredients found in Fen-phen. Fen-phen was taken off the market because it was linked to heart damage.


Initial clinical studies found the drug to be effective and comparatively safe, although 18 percent of participants in the study dropped out due to side effects such as memory and concentration problems. These side effects are associated with the pill’s other active ingredient, the anticonvulsant topiramate. Qnexa meets the FDA’s standard for effectiveness, which is a five percent decrease in body weight in more than 35 percent of people taking the pill. Some concern has been expressed that there are other, potentially more severe, side effects that are being overlooked.

The FDA has pending approvals on two other weight loss drugs currently, Lorcaserin and Contrave.

I don't think any of these pills will ever be the answer. Magical thinking....

I'd love to believe in a magic pill, but I do want my FDA to keep me from another fen-phen disaster. Let's hope this one proves out eventually.
