Abstract:

Objective A high performance liquid chromatography(HPLC) method with ultraviolet(UV) detection(230 nm) was developed and validated for the quantification of 5 drugs, Risperidone, clozapine, reboxetine, 9-hydroxy Risperidone and norclozapine, in human serum. Methods Following a one-step liquid-liquid extraction with diethyl ether, the analyte and internal standard(paroxetine) were separated using an isocratic mobile phase consisted of acetonitrile: methanol: butylamine: acetic acid: deionized water=20: 2.9: 1.1: 1: 34.3 on a reverse phase Inertsil C18-3 column. Five drugs and IS were separated well under the chromatographic condition. The calibration curve was verified over the range of 100~1 600 μg/L and limit of detection(LOD) was 25 μg/L(S/N=10). Results The imprecision of within and between batches were 3.1%~15.6% and 5.7%~18.4%, respectively. The accuracy of within and between batches were 0.1%~8.7% and 0.3%~13.3%. Commonly used psychotropic drugs did not interfere with the drugs and internal standard. Conclusion This method was found to be rapid, simple, accurate, sensitive and more suitable for rapid qualitative and quantitative determination of drugs in the serum of overdosed patients.
