ANALYTICAL METHOD DEVELOPMENT AND VALIDATION FOR ESTIMATION OF ZALEPLON IN PURE AND TABLET FORMULATION

A rapid and precise Reverse Phase High Performance Liquid Chromatographic method has been developed for the validated of Zaleplon in its pure form as well as in tablet dosage form. Chromatography was carried out on XBridge C18 (4.6×150mm, 5µ) column using a mixture of Methanol (100%v/v) as the mobile phase at a flow rate of 1.0ml/min, the detection was carried out at 253nm. The retention time of the Zaleplon was 2.4 ±0.02min. The method produce linear responses in the concentration range of 25-120µg/ml of Zaleplon. The method precision for the determination of assay was below 2.0%RSD. The method is useful in the quality control of bulk and pharmaceutical formulations. Keywords: Zaleplon, RP-HPLC, validation.
