OBJECTIVE To develop a method for determination of clozapine, olanzapine and mirtazapine in human plasma by liquid chromatography-tandem mass spectrometry(LC-MS/MS). METHODS Clozapine, olanzapine and mirtazapine were extracted from plasma samples by using diethyl ether and separated by Agilent Zorbax SB-C18 column(2.1 mm x 150 mm, 5 microm). Electrospray(More)
