The retention time of valsartan and hydrochlorothiazide were 2.65 min and 3.97 min, respectively. Validation of the method was done according to the ICH guidelines for different analytical parameters. The method was found to be linear over a range of 50-250 μg/mL for valsartan and hydrochlorothiazide. The established method was as reproducible with a %RSD value of less than 2 and having robustness and accuracy within the specified limits. Assay of marketed formulation was determined and was 99.04% and 99.8% respectively. The stressed samples were analyzed. The proposed method was found to be specific and stability indicating as no interfering peaks of degradation compounds and excipients were noticed. The proposed method can be successfully employed in the estimation of commercial formulations.

The mobile phase comprised of 0.02 N phosphate buffer (pH 5.5) and acetonitrile (55:45 v/v) was delivered with a flow rate of 1.5 mL/min. The method was linear over the concentration range 6.25-18.75 μg/mL (trithioparamethoxy phenylpropene) and 1.5-4.5 μg/mL (chlorpheniramine maleate). The limit of quantification was 1.57 μg/mL (trithioparamethoxy phenylpropene) and 0.969 μg/mL (chlorpheniramine maleate). The calculated recoveries were 100.083-100.287% (trithioparamethoxy phenylpropene) and 99.827-100.277% (chlorpheniramine maleate). Trithioparamethoxy phenylpropene and chlorpheniramine maleate were subjected to forced stress like acid hydrolysis, base hydrolysis, thermal and oxidation degradation. The drugs were found to degrade in the applied conditions. The degraded products were resolved effectively from the trithioparamethoxy phenylpropene and chlorpheniramine maleate.

A simple, accurate and precise stability indicating method was developed for the simultaneous estimation of the encorafenib (ECRB) and binimetinib (BMTB) in a dosage form by UPLC. Chromatographic elution was processed through a HSS C18 (100 x 2.1 mm, 1.8m) reverse phase column and the mobile phase composition of 0.01N KH2PO4 buffer (3.5 pH) and acetonitrile in the proportion of 55:45 was processed thru a column at a flow rate of 1.0 ml/min. Temperature of the column oven was kept at 30.0°C and the wavelength maximum of detection system was set to 294 nm. Retention times of ECRB and BMTB were found to be 0.767 min and 1.130 min respectively. Repeatability of the method was determined in the form of %RSD and findings were 0.3 and 0.6 for ECRB and BMTB respectively. The percentage recovery of the method was found to be 99.59% and 99.70% for ECRB and BMTB respectively. LOD, LOQ values obtained from regression equations of ECRB and BMTB were 0.51, 1.55mg/ml and 1.47, 4.44 mg/ml respectively. Regression equation of ECRB was y = 6684.x + 18102 and BMTB was y = 13118x + 2159. Two analytes were subjected for acid, peroxide, photolytic, alkali, neutral and thermal degradation studies and the results shown that the percentage of degradation was found between 0.76% and 6.88%. Retention times and total run time of two drugs were decreased and the developed method was simple and economical. So, the developed method can be adopted in industries as a regular quality control test for the quantification of ECRB and BMTB.
