The aim of this work was to develop a simple, fast and accurate liquid-chromatography-mass spectrometry method for determination and quantification of serum clomipramine. <o:p> </o:p> For serum clomipramine measurement, 200 µL of internal standard (acetaminophen solution) was added to 200 µL serum in a glass tubes. Tubes were well mixed for a minute and extracted twice with 3 ml of a solution of ethylacetate. After centrifuging at 3000 rpm for 10 minutes, the organic phase was transferred to small glass vials, dried completely under a steam of nitrogen at 400 0 C. Samples were reconstituted with 200 µL methanol and 10 µL was injected and analyzed by LC-MS/MS. <o:p> </o:p> We developed an analytical method for the simultaneous analysis of clomipramine in serum using liquid chromatography-mass spectrometry (LC–MS/MS) with multiple selected ion monitoring (SIM). The clomipramine assay was linear up to 200 µg/L. <o:p> </o:p> Serum clomipramine measurement can be easily performed by LC-MS/MS system to identify the risk of the patients with therapeutic drug monitoring. This method allows accurate the pathological levels with high linearity of the system. <o:p> </o:p> This method allows the exact determination of clomipramine levels in pathological concentration to avoid toxic effects. <o:p> </o:p> }, number={İssue 1 (1)}, publisher={Engin TUTKUN}
