DEVELOPMENT AND VALIDATION OF A SENSITIVE SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS ESTIMATION OF PITAVASTATIN CALCIUM AND FENOFIBRATE

摘要

A simple, rapid, accurate, precise and reproducible UV spectroscopic method has been developed for the simultaneous estimation of pitavastatin calcium and fenofibrate in bulk and pharmaceutical dosage form. The method is based on simultaneous equation method. Pitavastatin calcium and fenofibrate have absorption maxima (X_max) at 245 nm and 286 nm respectively. Beer's law was obeyed in the concentration range of 2-12 ug/mL and 32-192 ug/mL for pitavastatin calcium and fenofibrate, respectively. The recovery studies are indicative of accuracy of method and are found in between 97.66-107.22% and 103.33-110.55% for pitavastatin calcium and fenofibrate, respectively, at three different levels of standard additions. Precision studies showed satisfactory results.
