| Summary: | Introduction. High performance, expresness due to the using a column lenght of 10 cm and a particle size up to 2 microns are the advantages of the UHPLC method, that allows to prefer this method in the routine quality control in comparison with the others. Monolithic columns just started to find their application in the pharmaceutical analysis. Their peculiarity that the porous sorbtion layer is symthesized directly in the column. The sorbtion layer has the biporous structure: transport macropores with the practical size of 1.8-2 microns and mesopores with the partical size of 11-12 nm, where the substances separation is taking place. The aim of the work was to develop a simple method forį the quantitative determination of famotidine in the tablets by UHPLC method with using monolitic column that would reduce the time of analysis, reduce using of toxic reagents and volumes of solvents. Methods and materials. The famotidine tablets, containing 20 mg of active substance (Arterium Corporation, Ukraine), and famotidine substance (Nakoda Chemicals Ild, India) were chosen as objects of study. The sample solutions and the standart solution were prepared in concentration of 0.1 mg/mL. [.].
