Hodoodo CAT#: H329518
CAS#: 129029-23-8
Description: Ocaperidone, also known as R 79598, is a highly potent and efficacious dopamine-D2 antagonist with concomitant, equivalent serotonin 5-HT2 antagonism. Ocaperidone inhibited dopamine agonist (apomorphine, amphetamine or cocaine)-induced behavioral effects at low doses (0.014-0.042 mg/kg). Ocaperidone completely blocked the dopamine agonist behavior at slightly higher doses (0.064 mg/kg). Ocaperidone is expected to exert pronounced haloperidol-like effects on the positive symptoms of schizophrenic patients but with risperidone-like low extrapyramidal side effect liability and improved patient compliance.
