Peroral administration of lornoxicam, a new representative of the class of oxicams, in a total dose of 2-16 mg/kg produced a dose-dependent analgesic effect in rats with formalin-induced tail inflammation, as confirmed by the tail-flick and hot-plate tests. The maximum analgesic effect of lornoxicam during the formalin-induced edema development was observed upon a three-fold drug administration by the scheme 1/2, 1/4, 1/4 of the total dose (8-16 mg/kg, p.o.) with a 3 h interval prior to formalin injection into the rat tail base. Validity of using the tail-flick and hot-plate methods for evaluation of the analgesic effect of NSAID is discussed.
