A simple, accurate, economical and reproducible procedure for simultaneous estimation of atorvastatin calcium and ezetimibe in their tablet dosage form has been developed using, Q-absorbance equation. The method involves, the absorbance measurement at 235.5 nm (iso-absorptive point) and 246.0 nm (λmax of atorvastatin calcium), in methanol. Both the drugs, obey Beer-Lambert's law in the concentration range of 5-25 μg/ml. The results of analysis have been validated statistically and by recovery studies.
