DISPOSITION TOLERANCE TO METHADONE

 

AMNUAY THITHAPANDHA and PETER GOLD MAN

Summary: Evidence is presented in this paper to indicate that tolerance to methadone, a widely used synthetic narcotic, is dispositional in nature-i.e., metabolic inactivation of this narcotic does increase, with a resulting tolerance to its toxic properties. This is in contrast to tolerance to most narcotics such as morphine, because morphine tolerance seems to be adaptive or cellular tolerance.
