Action de la buprénorphine sur la sécrétion pancréatique externe chez le rat

: 2-deoxyglucose stimulates pancreatic secretion through a mainly vagal neural pathway. Buprenorphine antagonized this stimulation in a dose-related fashion between 0.017 and 0.45 mg/kg. i.v. The effect of buprenorphine was suppressed by naloxone, but not by alpha and beta-adrenoceptor blocking agents. The effect of methadone was similar, at doses about ten times larger.
