Worries over weight loss drug
In the US consumer watchdog Public Citizen issued a petition to the US Food and Drug Administration calling for a ban on the class of drugs called orlistat, which are known as Xenical and Alli. Both are they only FDA approved weight loss drugs in the US; however it’s believed that they can cause liver damage, pancreatitis and kidney stones.
Speaking about the weight loss drugs, Dr. Sidney Wolfe, director of Public Citizen’s Health Research Group said: “These drugs have the potential to cause significant damage to multiple critical organs, yet they provide meagre benefits in reducing weight loss in obese and overweight patients.”
Recent studies suggest that taking Xenical or Alli would only help people lose 4 to 6 pounds more than they would with only diet and exercise. According to Wolf “The benefit was never that great, but many people thought they’d take their chances.”
Worldwide it’s estimated that around 40 million people have taken either Xenical or Alli in the last decade, however GlaxoSmithKline who make the drug are finding a decrease in sales. According to a report released by Public Citizen Alli sales dropped from $145 million in 2007 to $84 million by mid-2010.
The weight loss drug Xenical was sold on prescription in 1997 and was touted as a breakthrough weight loss drug and in 2007 Alli became an over the counter approved weight loss drug. In the past the FDA have banned two previous market leading weight loss drugs, Fen-phen and ephedra, because of potentially fatal side effects. So it may only be a matter of time before they do the same again.
