Validated RP-HPLC Method for the Quantitative Estimation of Zidovudine in Bulk and Pharmaceutical Dosage Forms

A simple, specific, accurate, precise and sensitive reverse phase High Performance Liquid Chromatographic method has been developed for the quantitative estimation of Zidovudine in both pure and pharmaceutical dosage forms. A Venusil XBP C-18, 5 μm column having 250 × 4.6 mm internal diameter in isocratic mode with mobile phase containing Water: Methanol (50:50). The flow rate was 1.0 ml/min and the effluents were monitored at 266 nm. The retention time was 4.47 min. The linearity was in the range of 25–75 μg/ml. This method was validated for linearity, precision, limit of detection, limit of quantitation, accuracy, ruggedness and robustness. Statistical analysis proves that the method is reproducible and selective for the estimation of the said drug.
