Telmisartan quality control by validation of UV-spectrophotometric method

Abstract

The aim of current study was to validate spectrophotometric method with UV-detection for identification and determination of Telmisartan in 99.8 % ethanol in respect of analytical parameters: selectivity, linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy and precision (repeatability). For Telmisartan in 99.8 % еthanol at  max = 298 nm for A1%1cm and  the obtained results for А  0.2 and А  0.2 are: 1) А  0.2: at 3.10–6 g/ml  1.25.10–5 g/ml; A1%1cm: 725  823; : 37347  42335 2) А  0.2: at 2.5.10–7 g/ml  1.10–6 g/ml; A1%1cm: 1201  1567; : 61816  80651 Analytical parameter accuracy is represented by the degree of recovery, which in the corresponding confidence possibility suit the confidence interval: R СТ60: 100.31 %  102.05 %; R СТ80: 99.22 %  103.18 %; R СТ100 : 93.58 %  101.9 %. For precision is proved that all results for the quantities correspond to the relevant confidence interval: СТ60: 60.31 mg  60.77 mg; СТ80: 79.82 mg  82.18 mg; СТ100: 94.22 mg  101.58 mg.
