A structure of the antihypertensive drugs consumption in the population of several regions of the Russian Federation

Aim to study the characteristics of the consumption of antihypertensive (AG) drugs in the population of several regions of the Russian Federation the Samara region, the Nizhny Novgorod region and the Republic of Tatarstan. 
Material and methods. The range of AG drugs sold in the retail pharmaceutical market of the Samara and Nizhny Novgorod regions and the Republic of Tatarstan was selected for the study. To manage the obtained data, we used several methods like structural, comparative, logical, predictive, retrospective, graphic, marketing analysis. The results were processed using the normalization method and methods of mathematical statistics. 
Results. The monopreparations kept the main share of sales in each region: 90.22% in the Samara region, 90.85% in the Nizhny Novgorod region, and 93.72% in the Republic of Tatarstan). In 2021, the leaders in consumption were ACE inhibitors (28.41%, 26.61% and 32.7%, respectively in each region) and -blockers (25.87%, 29.02% and 21.15%). In total, these two subgroups accounted for more than a half of all monopreparations sold, counted in packages. In the subgroup of fixed combinations, the angiotensin II receptor blockers + diuretic were the most popular, which account for 35.38%, 29.73% and 22.13% of drug sales in this subgroup in the Samara, Nizhny Novgorod regions and the Republic of Tatarstan, respectively. In the subgroup of combined antihypertensive drugs, the multicomponent fixed combinations were among the leaders (10.22%, 8.20%, 12.10%, respectively in each region), however, in the total consumption of antihypertensive drugs, they accounted for less than 1%. 
Conclusion. This study revealed the features of the consumption of drugs prescribed for arterial hypertension in the Samara and Nizhny Novgorod regions, as well as in the Republic of Tatarstan in 2021. We identified the groups of antihypertensive drugs of most demand and found the leaders within these groups. It was established that there was a relationship between the volume of sales of antihypertensive medicines in physical terms (in packages) in the Samara region for the period 20172021 and the population of this region.
