ObjectiveTo establish an HPLC method for the determination of Candesartan Cilexetil Capsules.Methods The HPLC system was consisted of an Agilent SB-C18 column (4.6 mm×250 mm, 5μm) with the mixture of 0.05 mol/L ammonium acetate solution - methanol (22:78) as the mobile phase. The flow rate was 1.0 mL/min and the detection wavelength was 254 nm.Results The linear range was 2.5-25μg/mL and the regression coefficient was 0.9999 (n=5). The recovery of this method was 100.3 % , withRSD of 0.7 % (n=9).ConclusionThe method can be specific, accurate, simple and fast.
