A recent release from the European Medicines Agency has recommended the suspension of the weight-reducing drug rimonabant (which was also in trials for the treatment of nicotine dependence) from the market due to the development of undesirable psychiatric side effects, particularly symptoms of depression.1 This decision follows a similar one regarding rimonabant made by the US Food and Drug Administration last year for the same reasons. In November 2008, Sanofi-Aventis announced it was suspending marketing of rimonabant.2 Soon thereafter, Pfizer announced that it was terminating clinical trials with otenabant, a diet drug with a similar mechanism of action.3
