Abstract
A simple, precise, rapid and accurate reverse phase HPLC method was developed for the estimation of Etravirine in tablet dosage form. A RP Inertsil ODS-3V C-18, 250x4.6 mm, 5μm partical size, with mobile phase consisting of 0.03M Potassium Dihydrogen orthophosphate in water pH-3.2 with orthophosphoric acid and Acetonitrile in the ratio of 30:70 v/v was used. The flow rate was 1.0 ml/min and the effluents were monitored at 309 nm. The retention time was 9.111 min. The detector response was linear in the concentration of 80-240μg/ml. The respective linear regression equation being Y= 58030X + 86395.9 the limit of detection and limit of quantification was 0.1μg and 0.3μg/ml respectively. The percentage assay of Etravirine was 98.46%. 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 Etravirine in bulk drug and in its pharmaceutical dosage form.
