Development and validation of a RP-HPLC method for the quantification of sparfloxacin in pharmaceutical dosage forms.
Keywords:
Sparfloxacin, HPLC, method development, validationAbstract
A rapid and sensitive reversed phase high performance liquid chromatographic method has been developed for quantitative analysis of sparfloxacin in pharmaceutical preparations. The method was validated according to FDA, ICH and USP guidelines with respect to accuracy, precision, specificity and linearity. The method was developed using the mobile phase comprising 1% aqueous solution of acetic acid and acetonitrile in the ratio of 71: 29% (v/v) at a flow rate of 0.7 mL/min over C-8 bonded silica column at ambient temperature. The recovery was found to be more than 97% for each spiked samples of sparfloxacin demonstrative of accuracy of the protocol. Intraday and interday precision of the new method were less than the maximum allowable limit (RSD% 2.0) according to FDA. The method showed linear response with correlation coefficient value of 0.998. Therefore, the method was found to be accurate, reproducible, sensitive and less time consuming, and can be successfully applied for the assay of sparfloxacin formulations.Downloads
