France, Great Britain Ban Controversial Weight-Loss Medication

This week, France's Agency for the Sanitary Safety of Health Products (AFSSAPS) removed the weight-loss drug sibutramine from its list of approved medications. Sibutramine has been sold in France under the name Sibutral since 2001. The move comes in advance of an expected Europe-wide ban by the European Unions Health Commission. Great Britain has already banned the use of sibutramine.

Long-term studies by the AFSSAPS indicate that sibutramine may cause negative cardiovascular effects in almost half of patients. Other side effects linked to the drug include increased blood pressure, stomach and muscle pain, nausea, and mood changes including depression. Sibutramine also interacts unfavorably with a variety of other medications, making it difficult to prescribe safely.

European officials also report cases of sibutramine poisoning, linked to illegal imports of dietary supplements from China and Africa.

Britain's European Medicines Agency (EMA) recommended the suspension of sibutramine use and all drugs containing sibutramine, such as Reductil, Reduxade and Zelium. The EMA states that the drug presents risks which outweigh its benefits and that the drug has minimal weight-loss effect in most patients, mainly because patients immediately gain back any weight lost as soon as they discontinue the drug.

Sibutramine, which is manufactured by American pharmaceutical company Abbott, is also controversial in the United States. The Food and Drug Administration (FDA) recently acknowledged that sibutramine may increase the risk of heart attack and stroke in patients with a history of cardiovascular problems.

Liver Injuries Possibly Linked to Weight Loss Drugs

Federal regulators announced this week that they are investigating 32 cases of serious liver injury in individuals who are taking weight loss drugs. The drugs involved were promoted by pharmaceutical manufacturers Roche Holding and GlaxoSmithKline.

The United States Food and Drug Administration (FDA) stated that between 1999 and 2008, it received six reports of liver failure in patients who were taking the weight loss drug orlistat. Orlistat is currently sold over-the-counter as Alli by GlaxoSmithKline and in prescription form as Xenical by Roche.

Negative symptoms associated with use of orlistat include yellowing of the skin or whites of the eyes, weakness and stomach pain.

The FDA has not yet found a definite link between the reported liver injuries and the weight loss products, but the investigation is ongoing. The agency has not instructed physicians to stop prescribing the drug, but has issued a public alert to inform consumers that there are concerns about the medication.

Representatives from Glaxo stated that there is no evidence that Alli causes liver damage. Representatives from Roche weren't immediately available to comment.
