A simple, precise, accurate, rapid and reproducible reverse phase high performance liquid chromatographic procedure is developed for simultaneous determination of Ciprofloxacin Hydrochloride and Tinidazole in tablet formulations. The mobile phase used was a combination of acetonitrile: water: triethylamine (30:67:3) v/v and the pH was adjusted to 6.0±0.1 by addition of 50% ortho phosphoric acid. The detection of the tablet dosage form was carried out at 296 nm and a flow rate employed was 1ml/min. Linearity was obtained in the concentration range of 2-16 mg/ml of Ciprofloxacin Hydrochloride and 5 -55 mg/ml of Tinidazole with a correlation coefficient of 0.9992 and 0.9996 respectively. The results of the analysis were validated statistically and recovery studies confirmed the accuracy of the proposed method. The developed method has been successfully used for the simultaneous estimation of both drugs in commercial formulation.
