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. The above-mentioned technique was validated according to ICH guidelines.

For the simultaneous evaluation of Aceclofenac and Misoprostol using RP-HPLC, an accurate, rapid, economical, and straightforward, reliable assay technique was developed and demonstrated. The proposed method achieved effective chromatographic separation by using an inertsil ODS column (150mmx4.6mm, 3.5), acetonitrile, and 0.1 percent orthophosphoric acid (OPA) (50:50 v/v) as a mobile phase with a flow rate of 1 ml/min and a wavelength of 227 nm. The retention time (Rt) of Aceclofenac was 3.189 minutes and Misoprostol was 6.966 minutes. Chromatography was performed isocratically at room temperature with a run time of around 10 minutes. The suitability parameters of the system were investigated by multiplying the quality six times, and the results were well within acceptable limits. The linearity analysis was conducted at 10 percent to 150 percent stages, with a regression coefficient of 0.999. Aceclofenac and Misoprostol had LOD and LOQ values of 0.063 ug/ml, 0.063 g/ml, and 0.208 ug/ml and 0.208 g/ml, respectively. The drug was recovered at a rate of 98-102 percent, which means that the recovery is within reasonable limits. The validation results were satisfactory, and the approach was found to be suitable for bulk and formulation analysis. As a result, it was obvious that the proposed approach was ideal for routine pharmaceutical preparation review and quality control. Validation results were very close to the appropriate maximum. RSD values of less than 2.0 percent indicate that this approach is accurate and precise. The above method was used to perform a retail formulation assay, which showed that 100.24 percent of the formulation was present. Degradation stress conditions in acidic, alkaline, peroxide, and thermal media were investigated. Under ideal conditions, the established method provided efficient, precise, and accurate results. According to ICH guidelines, the approach was justified.

Methodology: The chromatographic separation was achieved on a Inert sustain swift (C18) column using a mobile phase comprising of perchloric acid and acetonitrile in a gradient mode at a flow rate of 1 mL/min. over a runtime of 50 minutes. All the eluants were monitored at 230 nm. The optimized method was validated as per ICH guidelines for various parameters. Results: The linearity of the method was proposed in the range of LOQ to 250 % for the drug and its impurities by subjecting the data obtained to statistical analysis using correlation coefficient model (r > 0.99). The method also gave acceptable recovery of all the four impurities at each level and was found to be accurate. The % RSD obtained in the method precision and intermediate precision were less than 2% depicting the precision of the method. The LOD and LOQ values were calculated based on the signal to noise ratio and are indicating the sensitivity of the method. The specificity of the method was checked in the presence of process related impurities and also degradants generated by exposing to a variety of forced degradation conditions.
