【 摘 要 】

A reliable, sensitive and selective spectrofluorimetric method has been developed for the determination of certain antidepressant drugs namely sertraline hydrochloride, fluoxetine hydrochloride, paroxetine hydrochloride, amineptine hydrochloride and bupropion hydrochloride in pure forms, pharmaceutical formulation and human plasma. The method is based on the reaction of investigated drugs with 5-(dimethylamino) naphthalene-1-sulfonyl chloride (dansyl chloride) in the presence of 0.5 M sodium carbonate to yield highly fluorescent derivatives, measured at 450 nm (excitation at 347 nm). The different experimental parameters affecting the development and stability of the reaction products were carefully studied and optimized. The calibration plots were constructed over the range of 0.02–0.14 μg mL−1. The proposed method was successfully applied for analysis of cited drugs in dosage forms. The high sensitivity of the proposed method allows the determination of investigated drugs in spiked and real human plasma. Statistical comparisons of the results with the reference methods show an excellent agreement and indicate no significant difference in accuracy and precision.
