title: Simultaneous determination of cefuroxime axetil and ornidazole in tablet dosage form using reversed-phase high performance liquid chromatography.
abstract: A simple, accurate and sensitive reversed-phase high performance liquid chromatographic (RP-HPLC) method for the simultaneous determination of cefuroxime axetil and ornidazole in combined tablet dosage form has been developed. The method was performed with a HiQ-SiL C18 column (250 mm x 4.6 mm) and photodiode array (PDA) detector, using 0.01 mol/L potassium dihydrogen orthophosphate-methanol (56 : 44, v/v) as the mobile phase and tinidazole as the internal standard. Beer's law obeys in the concentration ranges of 5 - 25 microg/mL and 10 - 50 microg/mL for cefuroxime axetil and ornidazole, respectively. The method has been successfully validated statistically and applied for the analysis of the drugs in pharmaceutical formulation.
