Short Communication Effect of trifluoperazine on carrageenan-induced acute inflammation in intact and adrenalectomized rats

Abstract

Abstract: The aim of present study was to investigate the effect of trifluoperazine (TFP) on carrageenaninduced rat's paw edema in intact and adrenalectomized (ADX). TFP (0.2 and 8 mg/kg) were given intraperitoneally just before the intraplantar injection of 0.1 ml of 0.5% carrageenan solution. After four hours, paw edema was assessed by calculating the paw volume changes and extravasations of Evans blue dye as inflammatory indicators. In both ADX and control groups, administration of TFP reduced inflammatory parameters (paw volume and tissue content of Evans blue dye) in inflamed paw. Our findings suggest that TFP can effectively reduce carrageenan-induced paw edema in both ADX and control rats. Therefore, antiinflammatory effect of these drugs does not need the adrenal gland activity
