Ethyl Amine

For simultaneous analysis of Dolutegravir and Rilpivirine utilizing RP-HPLC, an accurate, rapid, economical, quick and reliable assay technique was developed and tested. Successful chromatographic detachment using acetonitrile and 0.1 percent tri ethyl amine in the water of pH-2.5 adjusted with 0.1% orthophosphoric acid in 40:60 v/v as a movable phase with a flow of 1 ml/min and UV observation at 230 nm. Chromatography at ambient temperature was performed isocratically, and the run time was 10 min. By injecting the norm six times, device suitability parameters were studied and the findings were far below the acceptance criteria. The linearity analysis was performed at levels ranging from 10% to 150% and the R2 value was found to be 0.999. Precision has been found to be 0.8 for repeatability and 1.2 for intermediate precision. Assay of the commercialized formulation was performed by using the above method, and we get 100.01 percent was present. For routine analysis in drug testing, this chromatographic approach can be effectively implemented. By using the above technique, an assay of the marketed formulation was performed and found to be within the limit. Degradation studies were carried out on Dolutegravir and Rilpivirine, with a purity threshold greater than purity angle in all conditions and within the acceptable range.

A validated method for the estimation of the mebeverine hydrochloride, an anti-spasmodic agent, was developed which was simple, precise, rapid and accurate. A clear separated chromatographic peak was achieved on Apollo C18 (4.6x250 mm), 5-μm column. Mobile phase used in this separation was the mixture of methanol and water in the ratio of 90:10% v/v with a flow rate of 0.9 μL/min at ambient temperature. The detection was achieved at a wavelength of 265 nm. At the retention time of 3.9 min and tailing factor of 1.09, chromatographic peak was observed. As per the guidelines of ICH, the method was developed and was validated with respect to accuracy, linearity, specificity, precision and robustness. Correlation co-efficient obtained shows a good linear relationship of more than 0.998 in the concentration range of 5 μg to 30 μg. Mean % recovery of 99.2% was seen and %RSD for repeatability and intermediate precision was less than 2%.
