A UV spectrophotometric method was developed for the estimation of atorvastatin calcium & fenofibrate in tablet dosage form by using simultaneous equation method. The drug obeyed Beer’s law & showed good correlation near to 0.999. Absorption maxima of atorvastatin calcium & fenofibrate were found to be at 246 and 286 nm respectively. Beer’s law was obeyed in concentration rang of 1-10 μg/ml for atorvastatin calcium & 2-20 μg/ml for fenofibrate. The method has been validated for linearity, accuracy & precision. The recovery was more than 99%. The developed method was found to be accurate, simple, precise, economical, and selective for simultaneous estimation of atorvastatin calcium & fenofibrate in tablet dosage form.
