Weight Loss Drug QNEXA Not Approved by FDA, Stock Rises Anyway

The FDA has not approved the weight loss drug QNEXA, manufactured by Vivus, but the stock shares rose by almost 10 percent. Weight loss drug QNEXA works according to a recently published article in The Lancet medical journal. The 56-week trial involving more than 2,000 people found that people taking the weight loss drug lost more than 20 lbs. compared to the placebo group that lost less then 5 lbs. Interestingly, was not approved by the FDA in 2010 because of safety issues. Which is no surprise; these diet drugs have caused many problems and the FDA has been cracking down on weight loss pills.

Interestingly maybe the stock exchange will help influence the FDA”s approval. Indeed, even though the drug is not yet approved, the successful weight loss results have triggered the “shares in Vivus [to rise] nearly 10 percent in premarket trading and were recently up about 3.3 percent to $6.68,” according to the Wall Street Journal. Vivus is the company that makes QNEXA.

Many of us may remember the drug Meridia. According to the FDA”s website, “On October 8, 2010, the U.S. Food and Drug Administration (FDA) asked Abbott Laboratories to voluntarily withdraw from the U.S. market, its weight loss drug Meridia (sibutramine) because of clinical trial data indicating an increased risk of cardiovascular adverse events, including heart attack and stroke, in the studied population. Abbott has agreed to voluntarily stop marketing of Meridia in the United States.” According to the New York Times , because it caused tumors in rats.

Anyone who has struggled with dieting knows that losing weight and keeping it off is not an easy task. Not surprisingly, many people turn to dieting drugs hoping for a “magic pill” to help them lose weight and keep it off.  Another study from scientists at the University of Liverpool shows that most anti-obesity drugs do not yield long-term results because the medications don’t target emotional issues that affect a person’s appetite. If you are looking to lose weight fast, pills are probably not the answer. Appetite suppressant phentermine, which is approved by the FDA, causes heart problems, including racing heart rhythms, palpitations, insomnia and leaky heart valves have been reported after prolonged use.

At the end of the day, the smartest way to lose weight remains to eat a healthy diet and exercise.


  • I agree with the authors conclusion… eating healthy and excercising is the most sensible way to live. What we need to get away from is the obsession we have with being thin, especially when we equate skinny with beauty and self esteem.

  • I waited over 40 years for a magic pill, I was slowly dying. Two years ago I discovered an oral restrictive device made from floss. It attaches easily to molars and my food intake is reduced. I am able to speak, cough, chew… only much smaller. I am able to think and make good decisions without worrying if I am going to loose control.

    Instead of the”magic pill” I rely on a simple, inexpensive floss device without side effects. I finally gained control over eating!
