摘要
Chronic treatment with imipramine enhanced the locomotor stimulant response to quinpirole (0.3 mg/kg s.c.), a dopamine D2/D3 receptor agonist. Chronic, but not acute, blockade of the NMDA receptor with the non-competitive antagonist MK-801 (0.3 mg/kg i.p.) prevented the imipramine-induced potentiation of the quinpirole effect. The results suggest that NMDA receptors play a role in the development of supersensitivity to dopamine receptor agonists produced by chronic antidepressant treatment.
