Ibipinabant (IBI) is an orally active potent cannabinoid-1 receptor (CB1R) antagonist. This drug was studied for the treatment of obesity and psychotic disorders. However, the development of the drug was discontinued in November 2008. Now, ibipinabant is only used for laboratory research, especially structure-activity relationship studies into novel CB1 antagonists.
