摘要:
MK-801 [(+)-5-methyl-10,11-dihydro-5H-dibenzo(a,d)cyclohepten-5,10-imine maleate] was assessed for its discriminative stimulus properties in rats trained to discriminate ketamine (7 mg/kg) from vehicle. MK-801 generalized to ketamine in a dose dependent manner with a maximum effect at 0.2 mg/kg, while ketamine generalized fully at 10 mg/kg. These results indicate that ketamine and MK-801 may share a common mechanism of action, which is related to the phencyclidine recognition site in the brain.
