Taranabant

Taranabant (codenamed MK-0364) is a cannabinoid receptor type 1 (CB1) inverse agonist that was investigated as a potential treatment for obesity due to its anorectic effects. It was discovered by Merck & Co.

In October 2008, Merck has stopped its phase III clinical trials with the drugs due to high level of central nervous system side effects, mainly depression and anxiety.
