The effects of nifedipne and verapamil were compared on carrageenan-induced paw edema in rats and the results are summarized as follows: Carrageenan induced severe acute paw edema within 30 minutes and the maximum effect was achieved around 4 hours after administration. The carrageenan-induced paw edema was prominantly reduced by pretreatments of indomethacin (2mg/kg, p.o.) and nifedipine (10 and 20mg/kg, i.p.), whereas verapamil had no effect on the carrageenan-induced paw edema. These results suggest that calcium antagonists, nifedipine and verapamil, have a different effect on the inflammatory response induced by carrageenan.
