Dextromethorphan Hydrobromide

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.

Objective: The most important objective of the present research work is to develop simple, specific, rapid, accurate, and sensitive reverse-phase high-performance liquid chromatography method and validated for the qualitative and quantitative determination of valsartan in its active pharmaceutical ingredient and tablet dosage form according to ICH guidelines.Proposed Method: An isocratic separation was done using Phenomenex C18 column possess 75×4.6 mm, 2.6 μ,100 A0 dimensions with mobile phase composition of water:acetonitrile (30:70% v/v) by maintaining 1 ml/minute flow rate and response detected at a wavelength of 247 nm.Results: The retention time of valsartan was found to be 2.71 minutes, limit of detection and limit of quantification were observed at 1.24 μg/ml and 3.6 μg/ml concentration, respectively, and a calibration curve was linear in the concentration range of 5-50 μg/ml with coefficient of correlation 0.99. The percentage recovery (accuracy) was in the range of 98.9-102%, and the % relative standard deviation was observed to be <2%.Conclusion: The proposed method was validated for accuracy, precision, sensitivity, linearity, and robustness and successfully employed for the quantitative determination of valsartan in tablet dosage form in quality control department of pharmaceutical industry.

ABSTRACTObjective: Xanthium strumarium is a cocklebur or burweed belonging to family Asteraceae and commonly found as a weed, is widely distributed inNorth America, Brazil, China, Malasia, and hotter part of India. The herb is traditionally used mostly in treating several ailments. The present studydeals with development and validation of a reliable reverse phase high-performance liquid chromatography (RP-HPLC) method for the simultaneousestimation of Stigmasterol and β-sitosterol in the various extracts of the plant.Methods: The proposed method utilizes a Qualisil Gold C18 column (250×4.6 mm), 5 µm particle size, under isocratic elution conditions with themixture of acetonitrile:ethanol:water (85:14:1 v/v/v) at 25° as a mobile phase. An effluent flow rate of 1 ml/minute and ultraviolet detection at202 nm was used for the analysis of Stigmasterol and β-sitosterol.Results: The described method was linear in the range of range of 100-500 µg/ml and 10-500 µg/ml for stigmasterol and β-sitosterol respectively,with excellent correlation coefficients. The precision, robustness, and ruggedness values were also within the prescribed limits (<2%). The recoveryvalues were within the range, which indicates that the accuracy of the analysis was good and that the interference of the matrix with the recovery ofphytosterols was low. The phytosterols were found to be stable in a stock solution for 24 hrs (percentage relative standard deviation was below 2%)and no interfering extra peaks were observed under controlled stress conditions.Conclusion: The proposed method is simple, specific, precise, accurate, and reproducible and thus can be used as appropriate method for routineanalysis of X. strumarium phytosterols in quality control laboratories.Keywords: Xanthium strumarium, Reverse phase high-performance liquid chromatography method, Precision, Phytosterols, Quality control.
