A simple method of hollow fiber-liquid phase microextraction (HF-LPME) combined with gas chromatography (CC) was developed for the analysis of four phenothiazine drugs (promethazine, promazine, chlorpromazine and trifluoperazine) in human urine samples All variables affecting the extraction of target analytes including organic solvent type, stir ring rate, extraction time, extraction temperature, pH of sample solution and ionic strength were carefully studied and optimized Under the optimal conditions, the analytical performance of HF-LPME-GC-flame photometric detector (FPD) and HF-LPME-GC-flame ionization detector (FID) were evaluated and compared The results showed that the HF-LPME-GC-FID was more sensitive than HF-LPME-GC-FPD for the determination of four target phenothiazine drugs, while the signal peak shape and resolution obtained by HF-LPME-GC-FPD was better than that obtained by HF-LPME-GC-FID HF-LPME-GC-FPD/FID was successfully applied for the assay of the interested phenothiazme drugs in urine sample, and the excretion of the chugs was also investigated by monitoring the variation of the concentration of chlorpromazine in urine of a psychopath within 8 h after drug-taking The proposed method provided an effective and fast way for the therapeutic drug monitoring (TDM) of phenothiazme (C) 2010 Elsevier B V.
