Popis: Objective: The objective of this study was to develop and validate a novel ion-pair liquid chromatography method, in order to separate and assay of amlodipine/benazepril combination in capsules. This method was a fast, practical and additional choice in quality control laboratories. Methods: The chromatographic conditions comprised of a classical C 18 -type stationary phase (250 × 4.6 mm, 5μ), with a mobile phase consisting of: 45% of 10 - 3 M of cetrimide and 55% acetonitrile. The flow rate was 1 ml/min; the detection wavelength was at 242 nm, under ambient temperature. Results: The method was validated for linearity with correlation coefficients very close to one, the accuracy with mean recovery values between 95.0-105.0%, precision with relative standard deviations of the calculated concentrations less than 5.0% and specificity in the presence of degradation products and excipients. Conclusion: The results presented in this paper showed that the developed method was fast and applicable, for the separation and determination of amlodipine/benazepril combination in capsules.
