High-performance liquid chromatographic determination of nemonapride and desmethylnemonapride in human plasma using an electrochemical detection.

A high-performance liquid chromatographic method using an electrochemical detector (HPLC-ED) was developed for the determination of nemonapride and its active metabolite, desmethylnemonapride in human plasma. Nemonapride, desmethylnemonapride and moperone chloride, which was used as the internal standard (I.S.) in plasma, were extracted by a rapid and simple procedure based on C18 bonded-phase extraction, and were separated by C8 reversed-phase HPLC column. Nemonapride and desmethylnemonapride were detected by high conversion efficiency amperometric detection at +0.84 V. Determination of both nemonapride and desmethylnemonapride were possible in the concentration range at 0.25-5.0 ng/ml, and the limit of detection for each was 0.1 ng/ml. The recoveries of nemonapride and desmethylnemonapride added to plasma were 97.0-98.2% and 96.7-98.8%, respectively, with coefficients of variation of less than 7.2% and 10.3%, respectively. This method is applicable to drug level monitoring in the plasma of schizophrenia patients treated with nemonapride and to the study of pharmacokinetics.[1]
