Abstract
A simple, precise, rapid and accurate reverse phase HPLC method developed for the estimation of Telmisartan in tablet dosage form. Luna 5 μ C18, 250×4.6 mm, particle size 5 μm, with mobile phase consisting of 5 mM Phosphate buffer: Acetonitrile (60:40, v/v), pH 7.4 was used. The flow rate was 1 ml/min and the effluents were monitored at 295 nm. The retention time was 7.02 min. The detector response was linear in the concentration of 2-14 μg/ml. The respective linear regression equation being Y=61480X-10188. The limit of detection and limit of quantification was 0.06 and 0.18 mcg/ml respectively. The percentage assay of Telmisartan was 100.28±0.93%. The method was validated by determining its accuracy, precision and system suitability. The results of the study showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which is useful for the routine determination of Telmisartan in bulk drug and in its pharmaceutical dosage form.
