title: Psychopharmacological effects of nomifensine enantiomers.
abstract: The effects of enantiomers of nomifensine were compared in five psychopharmacological tests in which (+/-)-nomifensine is active. In mice, (+)-nomifensine increased motor activity at 16 mg/kg, 8 mg/kg reduced the hypothermia and ptosis induced by reserpine and antagonized the hypothermia induced by 16 mg/kg of apomorphine. (+)-Nomifensine 4 mg/kg potentiated yohimbine toxicity. (-)-Nomifensine 4,8, or 16 mg/kg was inactive in all these tests. In rats, (+)-nomifensine 8 mg/kg induced stereotyped movements whereas (-)-nomifensine 64 mg/kg did not produce stereotypies.
