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.

Rosuvastatin Calcium

A Simple, precise, and accurate stability-indicating reversed-phase high-performance liquid chromatography method has been established for the simultaneous estimation of rosuvastatin calcium and fenofibrate in combined bulk and tablet formulation. The chromatographic separation was performed on reverse phase Princeton (C18) (250 mm x 4.6 mm, 5µ) column with mobile phase as a mixture of water (pH adjusted to 3.0 with orthophosphoric acid) and acetonitrile in the ratio (40:60) v/v at the flow rate 1.0 ml/min. Detection was carried out at wavelength 240 nm. The retention time under the optimized condition of Rosuvastatin calcium and Fenofibrate was found to be 2.485 & 3.905 minutes respectively. The calibration curve was linear in the range of 6-16 µg/ml and 87-232 µg/ml for rosuvastatin calcium and fenofibrate with a correlation coefficient of 0.9999 and 0.9994 respectively. Relative standard deviation values for all key parameters were less than 2.0%. The percentage recovery was found to be 99.66-100.37% and 99.13-100.44% for rosuvastatin calcium and fenofibrate respectively. The developed reversed-phase high-performance liquid chromatography method was found to be simple, specific, sensitive, rapid, linear, accurate, precise, and economical, and could be used for regular quality control of rosuvastatin calcium and fenofibrate in bulk and tablet formulations.  Keywords: Rosuvastatin calcium, Fenofibrate, RP-HPLC, Method validation, ICH guidelines.
