Abstract
(1) Reserpine antagonizes the analgesia in mice induced by morphine, meperidine and codeine. (2) Five-hydroxytryptophane, 5-hydroxytryptamine, tryptamine, amphetamine, mescaline and epinephrine prolong and enhance morphine analgesia whereas iproniazid and choline-p-tolyl-ether fail to do so. (3) Possible mechanisms involved in the synergistic action of amines and the antagonistic action of reserpine on morphine analgesia are discussed.
