Abstract
Objective To establish and optimize a simple, rapid, reliable, high sensitive and high selective method for the determination of fluoxetine hydrochloride in plasma by high-performance liquid chromatographic (HPLC) so as to monitor the clinical drug use. Methods The plasma samples were deproteined by acetonitrile. Separation was performed on a Hypersil ODS2 column(5 μm, 4.6 mm×200 mm). The mobile phase contained acetonitrile-25 mmol/ L phosphate buffer(pH6.5)(34:66). The flow rate and sample volume injected were 1.2 ml/min and 20 μl, respectively. Detection wavelength was 227 nm. Results The calibration curve of fluoxetine hydrochloride in plasma was linear in the concentration range of 0.5~50 ng/ml and coefficient was 0.996 9. The intra-assay precision did not exceed 8.06% and inter-assay precision did not exceed 10.46% for low, medium and high quality samples, respectively. The average recovery of the described method was 91.7%,97.06% and 100.75%, respectively. Conclusion In comparison with previous work, the improved chromatographic method was more economical, less polluted and better protected column, besides simple preparation of plasma samples, high reproducibility, and high selectivity.
