A new, simple, accurate and sensitive UV-spectrophotometric absorption correction method has been developed for simultaneous determination of Candesartan Cilexetil and Amlodipine Besylate in bulk utilizing concept of standard addition. The method is based upon determination of Amlodipine Besylate at 237 nm & Candesartan Cilexetil at 254 nm methanol as a solvent. Overlay spectra of both drugs shows absorbance at 244 nm. Linearity was observed in range of 10–60 μg/ml and 2–10 μg/ml for Candesartan Cilexetil and Amlodipin Besylate respectively. The correlation coefficient value was found to near to 1. All methods were statistically validated as per ICH guidelines.
