Abstract
"Reverse tolerance" was produced in rats and mice by repeated exposure to either cocaine or amphetamine. The locomotorstimulant effect was studied in mice; stereotypy and convulsions in rats. MK-801, the NMDA antagonist, blocked the development of "reverse tolerance" to all three effects. In contrast, haloperidol selectively blocked "reverse tolerance" to cocaine-induced stereotypy but not to convulsions. The data suggest that the glutamate system participates in the mechanism of "reverse tolerance" to the dopaminergic effects of cocaine and amphetamine, as well as to the convulsant effect of cocaine.Entities:
