A new method for the estimation of olanzapine in human plasma is developed and validated. It utilizes RP select B column and amperometric detector. The mobile phase consisted of 75mM sodium dihydrogen phosphate buffer of pH 7.0, acetonitrile and methanol in 55:22.5:22.5 %v/v ratios in an isocratic mode at 1.5ml-1 flow rate. The drug is extracted in to 3ml each of Tertiary Butyl Methyl Ether (TBME) twice from plasma, evaporated and the residue dissolved in mobile phase. The percentage extraction is found to be more than 79% and the linearity range from 0.5ng to 50.0ng ml-1. The method has been validated extensively and found to have good interday and intraday precision. This method has been applied to study pharmacokinetics in 12 healthy human volunteers.
