To develop simple spectrophotometric method development for simultaneous estimation of Atorvastatin calcium (ATR) and Aspirin (ASP) in pure and combined capsule dosage form. The method employed simultaneous equation method (method-1) and Q-absorbance ratio method (method-2) using 242 nm and 222 nm as absorbance maxima (λmax) for ATR and ASP respectively and 232 nm as isoabsorbtive point. Methanol was used as a solvent. Linearity was observed in concentration range of 5-40 μg/ml for ATR and 5-30 μg/ml for ASP respectively. The method was validated statistically and recovery study was performed to confirm the accuracy of the method.
