Validated Rp-Hplc Method For Simultaneous Estimation Of Metadoxine In Bulk And Tablet Dosage Form.

Abstract

A rapid and precise reverse phase high performance liquid chromatographic method has been developed for the validated of Metadoxine, in its pure form as well as in tablet dosage form. Chromatography was carried out on a Phenomenex Luna C18 (4.6×150mm, 5µm) column using a mixture of Acetonitrile: Water (90:10%v/v) as the mobile phase at a flow rate of 0.9ml/min, the detection was carried out at 230nm. The retention time of the Metadoxine was 2.826 ±0.02min. The method produce linear responses in the concentration range of 10-50mg/ml of Metadoxine. 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.
