Abstract

  

A simple, specific, precise and accurate Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method was developed and validated for the estimation of Diltiazem HCl (Diltiazem Hydrochloride) in Bulk and Pharmaceutical dosage form. The chromatographic determination was performed on isocretic High performance liquid chromatography system of Agilent model no.1220. The separation was conducted by using column of Zorbax [C8 (5µ, 4.6mm×250)] with mobile phase consisting of buffer and Acetonitrile in the ratio of (60:40). The mobile phase was delivered at the flow rate of 1.0ml/min. The eluent was monitored at wavelength 240 nm and found a sharp and symmetrical peak with retention time of 4.66min. The method was validated for linearity, accuracy, precision, specificity, robustness. Recovery of Diltiazem HCl was found to be in the range of 98%-102%. The method was found to be linear over the concentration range 50-150 µg/ml with coefficient correlation r2 = 0.995. After developing method and studying validation parameter to obtain result complying with USP monograph.
