10.22376/ijpbs.2019.10.1.p1-12 Volume 2 Issue 3 2011 (July - September) The present study explores the Polyherbal formulation for Analgesic activity of ethanolic leaves extracts of lessThan i greaterThan Momardica charantia lessThan /i greaterThan Linn and lessThan i greaterThan Azadirachta indica lessThan /i greaterThan A. Juss agaist experimental model of Eddy's hot plate method And Heat conduction method response in rats. The effective dose of the extract for analgesic activity was calculated from dose-response curve by using the Eddy's hot plate method And Heat conduction method response in rats. Polyherbal suspensions were prepared by the trituration method using a suspending agent and ethanolic dried extract of leaves. The formulation of lessThan i greaterThan Momardica charantia lessThan /i greaterThan Linn and lessThan i greaterThan Azadirachta indica lessThan /i greaterThan A. Juss were evaluated for analgesic activity. In both of Eddy's hot plate method And Heat conduction method response in rats writhing response method; the intraperitoneal administration of formulation F1 and F2 induced a significant analgesic activity in a dose-dependent manner respectively in the rats. Formulation F1 has shown significant analgesic effect than the F2 with compare of Diclofenac sodium as a standard drug. The plant may have the phytoconstituents which inhibit cyclooxygenase enzyme or act on central opioid receptors. Pravin V. Gomase, Priti S. Shire, Sayyed Nazim 1 And Amol B.
