Ultra performance liquid chromatography method was developed for the simultaneous estimation of the Artemether (AMT) and Lumefantrine (LFT) in Tablet dosage form. Chromatogram was run through X-bridge C18 100 x 2.1 mm, 3.5m. Mobile phase containing Buffer 0.01N KH2PO4 (3.5pH): Acetonitrile taken in the ratio 55:45 was pumped through column at a flow rate of 0.3ml/min. Buffer used in this method was 0.01N KH2PO4. Temperature was maintained at 30°C. Optimized wavelength selected was 215nm. Retention time of AMT and LFT were found to be 0.787 min and 1.572min. %RSD of the AMT and LFT were and found to be 0.7 and 0.6 respectively. %Recovery was obtained as 99.49% and 100.22% for AMT and LFT respectively. LOD, LOQ values obtained from regression equations of AMT and LFT were 0.03, 0.08 and 0.095, 0.288 respectively. Regression equation of AMT is y = 19308x + 1509 and y = 36919x + 11566 of LFT. The developed method was simple and economical that can be adopted in regular Quality control test in Industries. Keywords: Artemether (AMT), Lumefantrine (LFT), Acetonitrile, UPLC.

Objective: This investigation demonstrates a stability-indicating and reliable “normal phase ultra-performance liquid chromatography” method to simultaneously quantify Ramucirumab and Erlotinib in the pharmaceutical dosage form. Methods: Successful separation was accomplished using Chiralcel-OD-3 column (50 mm x 4.6 mm, 3 μm) with an isocratic type of elution using a mobile phase containing n-hexane+isopropyl alcohol+methanol (89:10:1), respectively with 1.0 ml/min flow rate. The wavelength sensor was attuned at 266 nm to quantify Ramucirumab and Erlotinib. Results: Erlotinib and Ramucirumab peaks were eluted with fine resolution at retention times 1.7807 min and 3.175 min, respectively. In the 10-150 μg/ml and 1-15 μg/ml concentration ranges for Erlotinib and Ramucirumab, the calibration graphs were linear, with regression coefficients of 0.99928 and 0.99976, respectively. The suggested ultra-performance liquid chromatography approach has been shown as sensitive, precise, robust, accurate, specific and stability indicating through the resolution of Erlotinib and Ramucirumab from its degradation-based compounds. Conclusion: The established ultra-performance liquid chromatography technique was effectively extended to the evaluation of Erlotinib and Ramucirumab in the pharmaceutical dosage form and the test results appeared satisfactory.

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.

A simple, Accurate and precise method was developed for the simultaneous estimation of the Grazoprevir and Elbasvir in Tablet dosage form. Chromatogram was run through Kromosil C18 (250 x 4.6 mm), 5m. Mobile phase containing Buffer: Acetonitrile taken in the ratio 45:55 was pumped through column at a flow rate of 1 ml/min. Buffer used in this method was Di Potassium Hydrogen ortho Phosphate. Temperature was maintained at 30°C. Optimized wavelength selected was 215 nm. Retention time of Elbasvir and Grazoprevir and were found to be 2.503 min and 3.004. %RSD of the Elbasvir and Grazoprevir were and found to be 0.3 and 0.4 respectively. %Recovery was obtained as 98.17% and 99.83% for Grazoprevir and Elbasvir respectively. LOD, LOQ values obtained from regression equations of Grazoprevir and Elbasvir were 0.24, 0.73 and 0.06, 0.19 respectively. Retention times were decreased and run time was decreased, so the method developed was simple and economical that can be adopted in regular Quality control test in Industries.

The present study described a new, simple, accurate, and precise high performance liquid chromatography method for the simultaneous determination of Ambroxol and Doxofylline in combined tablet dosage form. The chromatographic method was standardized using a BDS hypersil C18, 250 mm × 4.6 mm, 5 μ (particle size), Thermo scientific from Germany with isocratic conditions, and mobile phase containing potassium dihydrogen orthophosphate buffer-pH 4.5 (0.05 M KH2PO4): acetonitrile (60 : 40) at flow rate of 1 ml/min using UV detection at 254 nm. The retention times of Ambroxol and Doxofylline were 3.510 min and 7.247 min, respectively. The method was linear over the concentration range for Ambroxol 3.75–11.25 μg/mL and for Doxofylline 50-150 μg/mL. The recovery of Ambroxol and Doxofylline was found to be in the range of 99.42–101.18% and 99.37–100.28%, respectively. The validation of method was carried out using ICH guidelines.

The present work describes a validated reverse phase high performance liquid chromatography (RPHPLC) method for simultaneous estimation of dextromethorphan hydrobromide and quinidine sulphate in pharmaceutical dosage from. The drugs were resolved using Hemochrom Intsil C18-5U column (250×4.6) mm in isocratic mode with mobile phase methanol: water (0.08% diethylamine, 0.02% of glacial acetic acid and pH 4.4 adjusted with orthophosphoric acid) in the ratio of 70:30 V/V at a flow rate of 1.0 mL/min. Retention time of dextromethorphan hydrobromide and quinidine sulphate were 4.9±0.2 and 3.6±0.2, respectively, at 292nm. The above mentioned method was validated as per International Conference on Harmonization (ICH) guidelines. Linear responses were obtained in concentration ranges of 5-35 μg/mL for dextromethorphan hydrobromide and 4-16 μg/mL for quinidine sulphate, with correlation coefficient (r2) of 0.999 for both the drugs. A simple, selective, accurate, precise, robust and reliable RP-HPLC method thus developed and validated for simultaneous estimation of dextromethorphan hydrobromide and quinidine sulphate.
