Abstract

The present study was investigated the effect of berberine on the development of behavioral sensitization by morphine, methampethamine, and cocaine. Repeated administration of morphine (10 mg/kg), methampethamine (2 mg/kg), and cocaine (15 mg/kg) produced behavioral sensitization in mice. Pretreatment with berberine (2 mg/kg) did not inhibit methampethamine-and cocaine-induced behavioral sensitization. (omitted)
