--- An analytical technique for high performance liquid chromatography to quantify the active ingredients metronidazole, clotrimazole and lidocaine hydrochloride, because the technique of analysis for the drug compound is not developed in official books. The analytical technique for the three substances is performed in two different chromatographic systems, so they cannot be quantified in a single chromatogram due to the large difference in the concentrations of active ingredients in vaginal ovules. Previously to the validation system suitability was evaluated. The results were in accordance with the specifications for a chromatographic method recommended by the USP 38, checking that the equipment, electronics, analytical operations and samples to be analyzed constitute an integral system that can be evaluated as such. To validate the performance parameters of the technique was evaluated as: Specificity, linearity, accuracy, precision, robustness and range. The method developed for metronidazole, clotrimazole, lidocaine hydrochloride is specific because it specifically identifies 3 active ingredients. It is linear over the range of selected concentrations (50% to 150% of the theoretical concentration), with a coefficient of correlation greater than 0.995. It is precisely because recovery rates between 98% and 102% were obtained. It is precision because the coefficients of variation were less than 2%. It is robust (for metronidazole alone) because making small changes is not affected by these changes. The results of these parameters are subjected to statistical tests showing that the analytical technique proposal for the quantification of the active ingredients is specified, accurate , precise , rugged and linear also ensuring the reliability of the new technique. Key words: metronidazole, clotrimazole, lidocaine hydrochloride, high performance liquid chromatography, validation, analytical technique.
