title: Modafinil reinstates a cocaine conditioned place preference following extinction in rats.
abstract: The current study examined whether modafinil would reinstate an extinguished cocaine conditioned place preference (CPP). Following extinction of a cocaine CPP, rats were administered modafinil (128 mg/kg), cocaine (5 mg/kg) or vehicle and given a 60-min reinstatement test. While the effect of cocaine was transient, modafinil robustly reinstated a cocaine CPP following extinction, suggesting that modafinil may induce relapse or increase the vulnerability of addicts to the reinforcing effects of environmental triggers.
