A VALIDATED RP-HPLC METHOD FOR THE ESTIMATION OF ZOLEDRONIC ACIDAbstract
A rapid and reproducible reverse phase high performance liquid chromatographic method has been developed for the estimation of zoledronic acid in its pure form as well as in pharmaceutical dosage forms. Chromatography was carried out on an ODS C18column (250 x 4.6 mm x 5 m length),using a mixture of methanol and 0.01M phophate buffer (pH-3) (60:40 v/v) as the mobile phase at a flow rate of 0.8 mL/min and the detection was done at 210 nm. The retention time of the drug was 3.812 min. The method produced linear responses in the concentration range of 0.25 to 60 g/mL of zoledronic acid. The method was found to be reproducible for analysis of the drug in parentral preparations.
