Taranabant is a highly selective cannabinoid-1 (CB1) receptor inverse agonist developed by Merck & Co for the treatment of obesity. The Phase III taranabant study involved about 2,400 patients and was to be conducted for two years. In March 2008, after completion of 52 weeks of the study, Merck reported positive results of the drug in conjunction with diet and exercise in obese patients. The patients experienced double the amount of weight loss by taking 2mg of taranabant when compared to the patients treated with placebo. However, in October 2008, the company discontinued the Phase III programme and clinical development of taranabant because of its side effects. The drug showed gastrointestinal and psychiatric side effects such as increased anxiety, depression and irritability. Merck had previously planned to file for regulatory approval with the US Food and Drug Administration in 2008, but subsequently withdrew it.
