abstract：BACKGROUND:The properties of methadone suggest a potential advantage for epidural over i.v. administration for pain relief, but little supportive evidence exists. METHODS:To investigate the pharmacokinetic and the pharmacodynamic properties of epidural and i.v. methadone, four doses of methadone (0.1, 0.25, 0.5, and 0...
