Two simple, rapid, accurate, precise, and economic spectrophotometric methods for simultaneous estimation of paracetamol and ibuprofen in pure and tablet dosage form have been developed. Method I is based on the simultaneous equation method. Paracetamol and ibuprofen show absorbance maximums at 256 and 222.4 nm respectively, so absorbance was measured at the same wave lengths for the estimation of paracetamol and ibuprofen. Method II is based on determination of Q-value. Absorbance is measured at 226.4 nm (Isoabsorptive point) and 222.4nm (λmax of ibuprofen). Both drugs obey the Beer Lambert's law in the concentration range of 5-30 µg/mL. Methods are validated according to ICH guidelines.
