The economic aspects of the pharmaceutical market are an important area of research that allows us to determine the level of sales of certain drugs, the dynamics of their sales, and ultimately, the demand for a particular group of drugs on the market. In the light of a sufficiently urgent problem - the spread of seasonal colds and viral diseases, as well as the still fairly high incidence of coronavirus infection both in Russia and around the world, we conducted an ABC- analysis of antiviral drugs in one of the pharmaceutical networks of the city of Belgorod (Russia). The purpose of this analysis is to determine the need to introduce into the range of pharmacies or exclude from it a particular group of antiviral drugs in order to form the range of antiviral drugs most in demand by consumers and, as a result, to increase the efficiency of the pharmacy network.
