Repeated intermittent administration of amphetamine in mice caused reverse tolerance to 5-hydroxy-L-tryptophan (5-HTP)-induced head twitch, as well as to amphetamine-induced stereotypy. The repeated administration of 5-HTP alone also resulted in reverse tolerance in the head-twitch test. Daily pretreatment with haloperidol prior to amphetamine administration blocked the development of both reverse tolerance to amphetamine and to 5-HTP, whereas daily pretreatment with cyproheptadine prior to amphetamine blocked only the reverse tolerance to 5-HTP. On the other hand, 5-HTP-induced reverse tolerance was blocked by daily pretreatment with cyproheptadine, but not with haloperidol. There appears to be no difference in the persistence of the reverse tolerance to 5-HTP, whether induced by amphetamine or by 5-HTP; in both instances, the persistence does not correlate with the persistence of reverse tolerance to amphetamine. The data suggest that the reverse tolerance to amphetamine and the associated reverse tolerance to 5-HTP are independent events, both of which are mediated by dopaminergic mechanisms.
