Development and Validation of a HPLC Method for the Determination of Lacidipine in Pure Form and in Pharmaceutical Dosage Form

A simple and reliable high-performance liquid chromatography (HPLC) method was developed and validated for Lacidipine in pure form and pharmaceutical dosage form. The method was developed on X bridge C-18 column (150 mm x 4.6 mm, 5 μm) with a mobile phase gradient system of ammonium acetate and acetonitrile. The effluent was monitored by PDA detector at 240 nm. Calibration curve was linear over the concentration range of 50-250 μg/ml. For Intra-day and inter-day precision % RSD values were found to be 0.83 % and 0.41 % respectively. Recovery of Lacidipine was found to be in the range of 99.78-101.76 %. The limits of detection (LOD) and quantification (LOQ) were 1.0 and 7.3 μg/ml respectively. The developed RP-HPLC method was successfully applied for the quantitative determination of lacidipine in pharmaceutical dosage. (author)
