Unfortunately, CB(1) receptor antagonism produced adverse psychiatric events in patients. To determine whether this occurs pre-clinically, we investigated the effects of rimonabant in rodent models of mood disorders. Chronic treatment with rimonabant increased immobility time in the rat forced swim test and reduced the consumption of sucrose-sweetened water in an assay postulated to… CONTINUE READING
