Abstract

In medical practice, the issue of the use of new domestic medicines becomes relevant, and the production of these medicines involves the development of regulatory documentation for their analysis. 

Objective: to develop the method of quantitative determination of Metronidazole and Clotrimazole in a soft medicinal form on titaniferous basis with the use of spectrophotometry method. 

Materials and methods. For analysis, we used substances, ethanol solutions of Metronidazole and Clotrimazole, an ointment under the conventional name Metroclotrimazole containing 1.0% of the preparations in Tizol gel. To carry out the research, spectrophotometry in the ultraviolet region was used with a SF-2000 device. 

Results. Studying the absorption spectra and performing the statistical processing of the analysis results, it was found that spectrophotometric determination of Clotrimazole and Metronidazole can be carried out at wavelengths of 260 nm and 312 nm, with a relative error of ± 1.88% and ± 1.57%, respectively. As a result of the study of the soft dosage form, it was found that the content of Metronidazole, found by the Fierordt method and the simplified system of equations, is in the range of 0.1028-0.1107 g, Clotrimazole - 0.0973-0.1117 g, which corresponds to acceptable standards. 

Conclusion. The studies conducted allowed us to develop and propose a method for the quantitative determination of Clotrimazole and Metronidazole in the ointment "Metroclotrimazole" spectrophotometrically, which enables to set the content of the drugs in the dosage form within the allowable regulatory deviations.
