A simple, specific and stability-indicating reversed-phase high-performance liquid chromatographic method was developed for the simultaneous determination of melitracen hydrochloride and flupentixol dihydrochloride in tablet dosage form. A Brownlee C-18, 5 μm column having 250×4.6 mm i.d. in isocratic mode, with mobile phase containing 0.025 M potassium dihydrogen phosphate: methanol (10 : 90, v/v; pH 7.3) was used. The flow rate was 1.0 mL/min, and effluents were monitored at 230 nm. The retention times of melitracen hydrochloride and flupentixol dihydrochloride were 7.75 min and 5.50 min, respectively. The linearity for melitracen hydrochloride and flupentixol dihydrochloride were in the range of 0.5–60 μg/mL. The recoveries obtained for melitracen hydrochloride and flupenthixol dihydrochloride was 99.81–100.77% and 99.42–100.12%, respectively. Both the drugs were subjected to acid and alkali hydrolysis, chemical oxidation, and dry heat degradation and photodegradation. The proposed method was validated and successfully applied to the estimation of melitracen hydrochloride and flupentixol dihydrochloride in combined tablet dosage form.

Abstract A new, simple column reversed-phase high-performance liquid chromatographic (HPLC) method for simultaneous determination of rabeprazole sodium (RAB) and domperidone (DOM) in a combined tablet dosage form has been developed and validated. Determination was performed using a Jasco HPLC system with a HiQ SiL octadecylsilane (C18) column (250 4.6 mm id), acetonitrile0.1 M ammonium acetate (50 + 50, v/v) mobile phase, and paracetamol as an internal standard. The detection was performed using a UV detector set at 280 nm. The method was validated with respect to linearity, accuracy, precision, and robustness. Beer's law was obeyed in the concentration range of 1.010.0 and 0.55.0 g/mL for RAB and DOM, respectively. The method has been successfully applied for the analysis of drugs in a pharmaceutical formulation.

A simple, accurate, rapid and precise isocratic reversed phase high-performance liquid chromatographic method has been developed and validated for determination of Doravirine in tablets. The chromatographic separation was carried out on Dionex C18 (250 x 4.6mm, 5µ) with a mixture of methanol: 0.05M potassium dihydrogen phosphate (40:60%v/v) as a mobile phase at a flow rate of 1.5 mL/min. UV detection was performed at 306 nm. The retention time was 5.24 min for Doravirine. Calibration plot was linear (r2=0.999) over the concentration range of 200-600 µg/mL. The method was validated for accuracy, precision, specificity, linearity, robustness, LOD and LOQ. The proposed method was successfully used for quantitative analysis of tablets. No interference from any component of pharmaceutical dosage form was observed. Validation studies revealed that method is specific, rapid, reliable, and reproducible. The high recovery and low relative standard deviation confirm the suitability of the method for routine determination of Doravirine in bulk and tablet dosage form.

A new simple high performance thin layer chromatographic method for simultaneous determination of rupatidine fumarate and montelukast sodium in bulk and tablet dosage form was investigated. Chromatographic separation of the drugs was performed on aluminum plates precoated with silica gel 60 F254 as the stationary phase and the solvent system consisted of acetone:methanol:toluene (2:3:5, V/V/V). Densitometric evaluation of the separated zones was performed at 286 nm and the method was validated. The Rf values and drug content of rupatidine fumarate and montelukast sodium were 0.57±0.02, 0.68±0.02 and 98.3%, 97.67% respectively. The calibration curves of peak area versus concentration, were linear from 50-300 ng per band for both rupatidine fumarate and montelukast sodium and the regression coefficient (r2 ) was greater than 0.99. The method was validated for linearity, accuracy, robustness and application for assay as per ICH guidelines. The study showed that the developed method was simple and accurate and would be suitable for the simultaneous determination of rupatidine fumarate and montelukast sodium in bulk and pharmaceutical formulations.
