This picture taken on October 23, 2008 in Paris, shows a pharmaceutical giant Sanofi-Aventis' anti-obesity drug Acomplia. EU authorities suspended sales of this drug across the continent, the firm announced that day, adding that it had not ruled out a worldwide halt. The EU has allowed sales of Acomplia since 2006, but the drug has not been authorised in the United States where authorities believe it encourages suicidal thoughts, even in patients with no history of depression.
