All over the world, non-steroidal anti-inflammatory drugs (NSAIDs) are taken annually by about three hundred million people and this figure is constantly increasing. At the same time, NSAIDs are also one of the most common causes of side effects of drug therapy. The development and implementation of new anti-inflammatory drugs, including those of plant origin, with minimal side effects is an urgent task of modern pharmaceutical science. Vaccinium corymbosum L. (family Ericaceae), which is gaining more and more popularity among berry crops and is successfully cultivated in Ukraine, is promising in this direction for research. The aim: phytochemical analysis of dry extracts from blueberry leaves to establish the possibility of creating new drugs with anti-inflammatory activity. Materials and methods. The objects of the study were dry extracts of northern highbush blueberry leaves. The content of amino acids and phenolic compounds was determined by HPLC and spectrophotometry. The prototypal activity was studied in vivo and in vitro. Research results. 4 dry extracts were obtained from northern highbush blueberry leaves. In the extracts obtained by HPLC, 7 amino acids were identified, including 3 essential ones: arginine, histidine, and phenylalanine. As a result of the HPLC study, 7 phenolic compounds were identified in extracts from the leaves of northern highbush blueberry: 5 flavonoids - rutin, quercetin-3-O-glucoside, kaempferol-3-O-glucoside, quercetin and kaempferol and 2 hydroxycinnamic acids, chlorogenic and caffeic acid. For the first time, the anti-inflammatory effect of extracts from blueberry leaves was investigated. It was revealed that extract 1 at a dose of 50 mg/kg and extract 4 modified with arginine at a dose of 25 mg/kg have the highest anti-inflammatory activity. Conclusions. The results of the conducted studies indicate that extracts from the leaves of northern highbush blueberry in terms of the content of biologically active substances are promising sources for the creation of new drugs and dietary supplements with anti-inflammatory activity

The aim. To conduct a structural analysis of the volume of government spending on the purchase of antituberculosis drugs (anti-TB D) within 2014–2018. Materials and methods. In the study, we used information on public procurement of anti-TB D for 2014–2018 presented on the website of the Ministry of Health of Ukraine in the section “Procurement of Medicines”, as well as statistical data of the “Center for Public Health of the Ministry of Health of Ukraine” on the incidence of multi-drug resistant tuberculosis (MDR-TB) in the population. Analytical and comparative, system, and logical methods, as well as economic analysis were used. With the help of synthesis the conclusions and recommendations were formed. Results. It was found that in 2014-2018, the MDR-TB incidence rate increase had a positive dynamics in reducing the number of registered cases. For example, in 2015 this indicator was 2.56 %, and in 2018 it was -7.93 %. It was proven that public procurement of anti-TB D in physical terms was chaotic. Thus, in 2015/2014, the growth rate of anti-TB D number was 35.55 %, in 2016/2015 – -31.59 %, in 2017/2016 – 15.31 %, in 2018/2017 – 6.13 %. It was found that the dynamics of the growth rate of purchases of TB D in the national currency and USD had some differences. For example, in 2015, expenses increased by 55.02 % in the national currency, while in dollar terms this indicator decreased by 15.64 % compared to 2014. At the same time, in 2018 there was a positive trend of increasing the volume of public spending in monetary terms. Thus, in 2018, the growth rate in the national currency was 53.16 %, and in USD – 49.83 %. It was found that in the structure of public spending there was a tendency for an insignificant predominance of foreign anti-TB D. Based on the comparative analysis of government spending on groups of anti-TB D by the priority of their use in treatment regimens according to the standards it was determined that the process of anti-TB D purchasing did not meet the priority criteria for treatment. It complicates the implementation of the process of reforming TB care in connection with the construction of an outpatient model.

The aim: to investigate the effect of a new derivative of 4-aminobutanoic acid (compounds KGM-5) on the level of neurotransmitters and neurotransmitter amino acids and the structural-functional state of the hippocampus of rats with acute cerebrovascular accident (ACVA). Materials and methods. ACVA was reproduced in rats by occlusion of the left carotid artery under anesthesia (sodium thiopental (35 mg/kg) intraperitoneally (i/p). 5 groups of animals were used: intact control (IC, n=6), untreated animals with ACVA (CP, n=13); animals with ACVA (n=14), which were treated for 5 days with KGM-5 at a dose of 30 mg/kg i/p, animals with ACVA (n=13), who received i/p comparison drug “Picamilon” (17 mg/kg). There was a group of pseudo-operated animals (POA, n=8). Withdrawal of animals from the experiment was performed on day 6 after modeling ACVA by painless euthanasia under anesthesia. Histological examinations of CA1 and CA3 zones of the ventral hippocampus were performed with staining of sections with thionine by the method of Nissl and hematoxylin, eosin. In the rat brain, neurotransmitter amino acids and neurotransmitters were identified. Statistical processing was performed using the W-Shapiro-Wills test to verify the normality of the distribution and the nonparametric Mann-Whitney U-test. The accepted significance level is p<0.05. Results. Under the influence of the compound KGM-5 and “Picamilon” in the CA1 zone of the hippocampus, the number of normochromic neurons increased by 20 % and 16.6 %, respectively, hyperchromic pycnomorphic neurons and shadow cells decreased respectively by 5.8; 2.9 times and 6.3; 3.5 times, the index of alteration of neurons decreased by 6 times and 4.8 times, respectively, the area of ​​the perikaryon of these neurons increased by 39.7 % and 77.8 %, respectively, compared with KP (p<0.05). Both studied agents showed a less pronounced normalizing effect on the CA3 area of the hippocampus. The new compound KGM-5 showed a normalizing effect similar to “Picamilon” on the level of neurotransmitter amino acids and neurotransmitters in the brain of rats with ACVA. Conclusions. Therapeutic administration of KGM-5 increases the survival of ventral hippocampal neurons, reducing the relative proportion of irreversibly altered cells, and helps to restore impaired levels of neurotransmitter amino acids and neurotransmitters in the brain of rats with ACVA. The neuroprotective effect of the new compound KGM-5 corresponds to this comparison drug “Picamilon”

The aim of the work is to study the features of effective management of product's assortment in small, medium and large pharmacy chains. Materials and methods. The study of the features of the assortment policy of pharmacies that are part of pharmacy chains of different sizes was conducted using a questionnaire of 421 heads of pharmacies. The relationship between the size of the pharmacy chain and the approaches used to form the product's assortment is studied and the presence of the procedure of product's assortment formation in pharmacies is analyzed using Pearson's criteria c2 and c2 maximum likelihood (M-L c2). The importance of the influence of the size of the pharmacy network on the scores of the efficiency of the business process of forming the product range, as well as its width and intensity of updating using non-parametric analysis of variance Kraskal-Wallis; Manfer-Whitney test with Bonferroni correction for pairwise comparisons of pharmacy network clusters and correlation analysis. The presence of drugs in treatment protocols was analyzed using the Z-test to compare the frequency of drug administration. Peculiarities of introduction and withdrawal of drugs and medical products to the range of different size pharmacy chains criteria c2 Pearson's and maximum likelihood (M-L c2) are determined. System and logical analysis is used to systematize the existing approaches to product's assortment management in pharmacy chains of different sizes. Results. It is established that with the increase in the size of pharmacy chains the tendency to use a centralized approach to the analysis and formation of the range in chains increases, when the list of assortment items is fully created and approved at the head office of the chain. The importance of the relationship between the breadth of the assortment of pharmacies and the size of the chain, which includes a pharmacy. Thus, large and mega-chains support the assortment, which on average includes up to 8.5 thousand items of medicines and medical devices, medium - 4-5 thousand assortment's items, and in half of the establishments of small pharmacy chains the range may include from 2,5 to 3 thousand names of medicines and medical devices. It is established that regardless of the size of the pharmacy chain, the inclusion of medicines / medical products in the range of pharmacies most often takes into account the factor of seasonality of demand and taking into account the core range, i.e. the list of 100-150 most popular items in the pharmaceutical market. When withdrawing medicines or medical products from the assortment of pharmacies from all three clusters are often guided by indicators of low profitability of sales and lack of orders for goods for more than three months. Conclusions. The analysis of the assortment policy of pharmacy chains of different sizes showed that in most of the studied institutions it is quite effective. The obtained results allow us to conclude that the effectiveness of the formation and analysis of the assortment is achieved through the use of different approaches to the centralization of this business process depending on the size of the pharmacy chain

The aim: to conduct epidemiological studies on cancer of the trachea, bronchi, lungs as important components in the development of effective directions for increasing the effectiveness of pharmaceutical support for cancer patients in Ukraine. Materials and methods. The study used data from special literature, which presents the results of research on cancer in different countries of the world and data from the National Cancer Registry from 2014-2019 by indicators of morbidity and mortality of the population of Ukraine from cancer of the trachea, bronchi and lungs, including by gender. General theoretical (historical, analytical-comparative, systemic, graphic, logical, hypothetical-deductive) and applied (mathematical-statistical, epidemiological) research methods were used. Results. It was found that during 2014-2018 in terms of morbidity and mortality of the population from cancer of the trachea, bronchi and lungs in Ukraine, there was a positive dynamics of decline. So, in terms of incidence rates, which are standardized by WHO in 2018, the data decreased compared to 2014 by 8.4 %, and according to the “Ukrainian standard” – by 7.0 %. Mortality rates, which were standardized by WHO, decreased in 2018 compared to 2014 by 12.1 %, and those presented according to the “Ukrainian standard” – by 11.1 %. It was proved that the average data on morbidity and mortality of male patients were 6.2 and 7.4 times higher than in the same data for female patients. The different nature of changes in morbidity and mortality rates of patients in accordance with their gender in the dynamics of years has been established. So, for the female cohort of patients, the incidence and mortality rate from cancer of the trachea, bronchi and lungs during 2014-2018 had a complex zigzag character of changes, and in 2019, compared with the data of 2014, they increased by 22.54 % and 23.6 %, respectively. In the male cohort of patients, we observed a positive trend towards a decrease in mortality during 2014-2019. So, in 2019, these indicators reached their minimum and were equal to 57.0 and 44.0 cases per 100 thousand population. According to the data of 2019, the incidence and mortality of men from cancer of the trachea, bronchi and lungs relative to the data of 2014 decreased by 21.4 % and 25.0 %, respectively. It looks encouraging that there was relatively little fluctuation during 2014-2019 epidemiological indicators, both in general for the entire population of patients and female patients. Conclusions. The established characteristics and trends in the formation of the onco-epidemiological profile of the country's population for trachea, bronchus and lung cancer in dynamics over the years necessitate further research, taking into account changes in the main demographic indicators development of society
