Mavatrep (1, 3, 10, 30 mg/kg; p.o.; single) shows complete reversal of thermal hypersensitivity both in CFA model of inflammatory of pain and (0.1, 0.3, 1, 3, 10 mg/kg) carrageenan model of inflammatory pain.
Mavatrep (10 mg/kg; p.o.; single) exhibits substantial bioavailability in the rat (51%).
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
