Rosonabant (INN; E-6776) is a drug acting as a CB1 receptor antagonist/inverse agonist that was under investigation by Esteve as an appetite suppressant for the treatment of obesity.[1][2] Development of the drug for clinical use was apparently halted shortly after the related CB1 antagonist rimonabant was discontinued, likely due to the reports of severe psychiatric adverse effects such as anxiety, depression, and suicidal ideation associated with it and with similarly-acting agents.[3][4]
