The effects of progabide (SL 76002) on locomotor activity and conditioned place preference induced by d-amphetamine

The effect of prior treatment with a GABA mimetic, SL 76002 (100 mg/kg i.p.), on amphetamine-induced locomotor activity and conditioned place preferences with amphetamine (1.5 mg/kg i.p.) was investigated. SL 76002 significantly attenuated the motor stimulant effects of amphetamine, without influencing the rewarding properties at least as determined by the place preference procedure. When injected alone, SL 76002 did not affect handling-induced locomotor activation, nor did it exhibit any aversive or reinforcing properties. The results suggest that separate neural systems may subserve the motor and rewarding properties of amphetamine.
