Galantamine attenuates reinstatement of cue-induced methamphetamine-seeking behavior in mice

Abstract

Methamphetamine (METH) dependence is becoming a serious socioeconomic health problem worldwide. The enhancement of the cholinergic nervous system is expected to greatly alleviate drug dependence. We investigated the effect of galantamine on the reinstatement of cue-induced METH-seeking behavior using a self-administration experiment. Treatment with galantamine (1 mg/kg, p.o.) 30 minutes before exposure to the cues suppressed the reinstatement of METH-seeking behavior. However, galantamine did not affect the cue-induced reinstatement of food-seeking behavior or locomotor activity. These results suggest that galantamine may be a candidate drug for treating relapses of METH-seeking behavior.
