Abstract An efficient, sensitive, and simple method was developed for the simultaneous determination of rosiglitazone and metformin hydrochloride in a combination tablet dosage form by column high-performance liquid chromatography. The mobile phase used was ammonium dihydrogen phosphate adjusted to pH 5.25 with sodium hydroxide. The limits of detection and quantitation were in the range of 0.51.6 g/mL, respectively, for metformin hydrochloride, and 0.002010.0067 g/mL, respectively, for rosiglitazone. The linearity was studied in the concentration range of 0.120.31 g/mL for rosiglitazone and 30.676.7 g/mL for metformin hydrochloride. The recovered amounts of metformin hydrochloride and rosiglitazone were 100103.8 and 101103.7, respectively.

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.
