Previous in vitro and in vivo studies have determined that the d isomer of methadone has N-methyl-D-aspartate (NMDA) receptor antagonist activity. The present studies examined the ability of d-methadone to attenuate the development of morphine tolerance in mice and rats and to modify NMDA-induced hyperalgesia in rats. A decrease in the percentage of mice analgesic (tail-flick response) after 5 ...
