Mediator® (Servier) Scandal in France Part I
The French privately owned pharmaceutical company Servier invented two of the drugs implicated in the US Fen-Phen scandal of the 1997. The amphetamine derivatives Fenfluramine and Dexfenfluramine were licensed to the US companies and were marketed by Wyeth. The drug combo for weight loss caused heart valve defects, hospitalizations and several deaths. Wyeth had to spend 21 billion dollars for class action and product injury related l litigation. Servier escaped any punitive damages payouts and failed to learn any lessons and was able to market another amphetamine derivatives in the French market.
A diabetes drug Mediator® (benfluorex, Servier) was launched in 1976 for overweight diabetes patients. The company Servier deftly turned its use for the unapproved indication of weight loss and appetite suppression. Isomeride a related derivative marketed by Servier was banned in 1997 in France. Benfluorex is an amphetamine derivative which is widely used as an appetite suppressant. The drug was approved in several countries under the mutual approval or under national registration schemes. The drug was banned in the US, and rest of EU in 1999. Spain and Italy banned the drug in 2004, Switzerland in 1997. Another appetite suppressant of the same class developed by Servier and marketed by Wyeth was banned in the US in 1997. Mediator® was allowed to remain in the market in France due to high level political connection, political contributions and kickbacks. A study by French Agency for health products (AFSSAPS) showed that the drug was taken by 5 million persons and probably linked to heart valve defects and may have caused between 500-2000 deaths in France during 33 years of marketing.
The drug was banned in France in November 2009, almost 10-12 years after it was withdrawn from the rest of the world. To add fuel to the fire, Jacques Servier has dismissed the 500 deaths as minor issue and not linked to Mediator® use. The company has rejected the drug safety body estimate as theories based on extrapolations and stated that millions have benefited from its use. Company estimate say that 2.5% of the French population has heart valve defects and the risk increase with age and diabetes.
