A new simple high-performance thin layer chromatographic method for determination of cefuroxime axetil and ornidazole in combined tablet dosage form is developed and validated. Cefuroxime axetil is second-generation cephalosporin used to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. Ornidazole is used to cure protozoan infections. The separation is carried out on Merck precoated silica gel aluminium plate 60 F(254) using toluene-n-butanol-triethylamine (8.5:2:0.5, v/v/v) as mobile phase. Quantitative determination of drugs is carried out by densitometric scanning of plates at 285 nm. The retention factor for ornidazole and cefuroxime axetil is found to be 0.51 +/- 0.007 and 0.67 +/- 0.009, respectively. The method is validated with respect to linearity, accuracy, precision, and robustness. Response found to be linear in the concentration range of 100-500 ng/band for both cefuroxime axetil and ornidazole. The method has been successfully applied for the analysis of drugs in pharmaceutical formulation. The % assay is found to be 102.36 +/- 0.775 and 101.00 +/- 1.192 for cefuroxime axetil and ornidazole, respectively.
