Popis: The analgesic ED 50 of tilidine administered orally to rats was 15.4 mg/kg at 15 min and 17.2 mg/kg at 30 min. The drug was metabolized quickly and extensively, and it and its principal metabolite readily crossed the blood-brain barrier. Analgesia after the oral administration of tilidine fumarate to rats was correlated with levels of this metabolite in plasma and brain, and with the tilidine levels in plasma. It appears probable that the conversion of tilidine into its metabolite. which has analgesic properties, is closely related to the analgesic state.
