No magic pill has ever come out that could help Americans become lean and fight obesity but FDA at the moment is scrutinising a pill that leads to weight loss.

There have been calls that the diet drug Meridia can be removed from the market and a Food and Drug Administration advisory panel will decide Wednesday about what can be done in this regard.

There is another drug, known as lorcaserin, which has come up before an advisory committee and its developer will be questioned by panelists and a possible recommendation for agency approval.

There are estimates of the U. S. Centers for Disease Control and Prevention that state two in three Americans are overweight and one in three are obese and following these facts the market is in a dire need of a magic pill.

In more than a decade, since 1999 when Xenical, which works by blocking the absorption of fat, was approved, there has not been a prescription pill for weight loss approved.

Doctors stated that Xenical’s version called Alli was given a go-ahead by the FDA to be sold over the counter, but many consumers were kept away from taking it following its gastrointestinal side effects like diarrhea.

Both Meridia and Xenical failed to be recognized as big sellers.

Dr. Robert Kushner, medical director of the Northwestern University Comprehensive Center on Obesity said, "Those of us who are in this business are pretty concerned as well as frustrated that there are not more treatments."
