Abstract

  The renin inhibitor aliskiren was determined spectrophotometrically with amlodipine in its combined tablet formulation. The UV-spectrophotometric method utilized dual wavelength method for simultaneous estimation of aliskiren and amlodipine. From the overlain spectra of two drugs, the set of two wavelengths λ1 (235.6 nm) and λ2 (242.2 nm) were selected for estimation of aliskiren. Amlodipine was estimated directly at 365 nm as a single component without any interference, as aliskiren has zero absorbance at this wavelength. Developed method obeys Beer’s law in the concentration range used for estimation of aliskiren and amlodipine. The mean percentage label claim of aliskiren and amlodipine using dual wavelength method was found to be 99.90 and 99.85, respectively. Accuracy of the method was found between 100.20 - 100.65%.
