Analgesic effect of morphine: A role for β-endorphin

Research output: Contribution to journalArticlepeer-review


Capsaicin, a neurotoxic agent that induces a decrease in hypothalamic β-endorphin, a specific antiserum and human β-endorphin fragment 6-31, a peptidergic β-endorphin antagonist have been used in the attempt of selectively affecting the function of β-endorphinergic system and of evaluating the possible role of this peptide in the analgesic effect of morphine. All 3 experimental approaches resulted in a decrease of the analgesia induced by morphine, thus suggesting that β-endorphin is involved in the effect of morphine.
