Action of tilidine hydrochloride and morphine hydrochloride on ventilatory control in normal subjects

Abstract

The action of tilidine hydrochloride and morphine hydrochloride on the ventilatory response to inhaled carbon dioxide has been assessed in 10 normal volunteers. In doses of 50 mg and 100 mg given intravenously, tilidine hydrochloride induced less respiratory depression than 10 mg of morphine given intravenously. Side effects were not different or troublesome with either drug. Depending on its relative pain relieving property, tilidine hydrochloride may have advantages over morphine as an analgesic.
