Abstract
We have developed a completely unique and reliable HPLC technique for simultaneous quantification of Lopinavir and Rilpivirine. Chromatographic detachment was attained on a X-bridge phenyl column (150x4.6mm, 3.5 µ) using isocratic elution with a buffer containing buffer and acetonitrile with the proportion of 70:30 as movable phase with a flow of 1 ml/min at room temperature and UV detection was carried out at 250 nm. Dissolve 1ml of tri ethylamine in 1 lt of HPLC grade water and filter through 0.45 µ filter paper, this solution was used as buffer. 8 min. run time was used to separate Lopinavir and Rilpivirine. Analysis was achieved within 15 min over an honest linearity within the concentration range from 20-300 µg/ml of Lopinavir and 2.5-37.5 µg/ml of Rilpivirine. By injecting the standard six times, system suitability parameters were studied and the outcomes were under the acceptable limit. Precision and recovery study results were found to be within the suitable limit. By using the above technique, assay of Lopinavir and Rilpivirine was performed and found to be within the limit. Degradation studies were carried out on Lopinavir and Rilpivirine, with a purity threshold greater than purity angle in all conditions and within the allowable range. The above mentioned technique was validated according to ICH guidelines.
