Mon, 15 Mar 2021 00:00:00 +0200

Pharmaceutical care for treating dorsalgia is not only of medical significance, but also has a socio-economic aspect. Back pain often occurs in the working-age population. The dorsalgia treatment requires substantial economic costs and leads to deterioration in the quality of life.

Aim. To analyze and systematize the official sources concerning medicines for treating dorsalgia at the domestic pharmaceutical market, as well as to determine promising directions for expanding the drug assortment.

Results. The results of the study have shown that the consumption of non-steroidal anti-inflammatory drugs (NSAIDs) occupy a leading position by the volume of consumption. In Ukraine, 36 trade names (TN) of medicines with the active substance Paracetamol were registered (re-registered), including 45 % registered drugs under the brand name. The ratio of domestic and foreign NSAIDs is 56 % to 44 %; the proportion of oral dosage forms constitutes almost 50 % of the assortment. The majority of foreign medicines registered in Ukraine are manufactured in European countries, which makes up 38.9 % of the total imports of medicines. France and Great Britain occupy the leading positions in terms of supply with six THs each. The total number of drugs for external use for joint and muscle pain is 131 TH. The macro-contour of the segment of herbal medicines for treating dorsalgia at the pharmaceutical market has been formed. According to the ATX classification, the drugs studied are mostly of the pharmacotherapeutic group M02AX – Other topical products for joint and muscular pain; they are produced mainly by domestic manufacturers (60 %). More than 30 % of them are supplied by the pharmaceutical enterprise Pharmaceutical Factory Ltd. (Zhytomyr). Multi-component medicinal products of plant origin prevail significantly (66.7 %); ointments represent the broadest range (60 %).

Conclusions. The limited range of drugs based on plant substances has been found; it contributes to the search for promising plant objects and the creation of new drugs based on them for the local treatment of dorsalgia.

The aim of the work is to scientifically substantiate the basic aspects of developing a methodology for including сost-effectiveness analysis in key processes of clinical trials of medicines.

Results. It is established that Ukrainian regulatory system and methodological support of clinical trials with included сost-effectiveness analysis is based on separate regulations in the field of clinical trial and health technology assessment. At the same time, there is no methodological support for the management of сost-effectiveness analysis alongside clinical trials, which would take into account the peculiarities of planning, organizing and conducting such studies. The algorithm of substantiation, development and inclusion of basic components of the analysis of economic effectiveness in the basic processes of planning and the organization of clinical trial of medicines is offered. Emphasis is placed on the need for a proper strategy for analyzing the economic efficiency of the studied medical technologies in clinical trials. The importance of proper selection of economic evaluation models (cost minimization, cost-effectiveness, cost-benefit) in accordance with the purpose of the clinical trial, the primary hypothesis and the selected primary and secondary endpoints is determined.

Conclusions. It is determined that there are certain problems of methodological and organizational nature for the development of clinical trials with included сost-effectiveness analysis and economic endpoints. The solution of these tasks should begin at the planning stage of the study by implementing the basic step-by-step recommendations. Innovative treatment technologies that have potential health benefits are often investigated in clinical trials. Thus, the introduction of pharmacoeconomic analysis methods into the structure of traditional clinical trials is an additional important tool to ensure the effective functioning and development of health technology assessment. In further research it is planned to develop scientific and practical approaches to ensure the proper implementation of management processes of сost-effectiveness analysis alongside clinical trial and analysis of data on their results.

Study of consumer awareness of contraceptives selecting in the family planning process

T. V. Mahanova, N. O. Tkachenko — Mon, 15 Mar 2021 00:00:00 +0200

The work aim is to study the degree of awareness of female consumers about the range of contraceptives and their use, as well as the process of providing contraceptives with the subsequent use of the results obtained to improve the contraceptives supply system for the right strategic marketing decision-making.

During the study methods of searching, analyzing, generalizing data from information sources, systemic, comparative, marketing analysis, and survey were used.

Results. Before the survey, the modern assortment of contraceptives study and an information array of them was formed, which was used to conduct conjoint analysis. At the same time, a survey among female respondents regarding their awareness of contraception issues was conducted.

As a result of the survey, 420 questionnaires with full valid answers of women aged 16 to 49 years were collected. Each of the groups covered a 4-year age interval. In addition, 117 refusals of women to participate in the survey were collected. The reasons of refusals were also taken into account in the study for a broader understanding of the functioning problems of a modern contraceptives supply system.

Conclusions. It was found that the degree to which women are familiar with the modern arsenal of contraceptives varies depending on their age. Overall, 78% of women are partially familiar with the entire range of contraceptives. The percentage of women who had a deficit of information about the range of contraceptives increases with the transition to older age groups: after the age of 30, every sixth woman in Ukraine does not know about the existence of some types of contraception.

Among women who were familiar with the entire range, the age group of 25-29 years prevails, which is associated with active family planning processes in this age range - 6.42%.

Women's views on the process of providing contraceptives and men's role in this process were analyzed. Thus, of the total number of respondents, 117 (21.78%) women refused to take part in the survey, explaining their refusal by their lack of interest in this topic, ignoring the use of contraceptives, or by their shyness. This "taboo" of the topic is closely related to the problems of sex education, problems of motivation and involvement of medical representatives in the dissemination of information about contraceptives and their importance in the process of family planning.

In addition, 69% of women prefer to coordinate the choice of contraceptives with their husbands, and only 20% of female consumers, believe that the process of preventing or planning a pregnancy is personally a woman's business.

The results of the survey prove the need to intensify health education work to improve the level of education of women and men on contraception, as well as expanding the boundaries of access to contraceptives for the target consumer.

A. S. Koval, S. V. Birukova, Y. V. Voyda — Mon, 15 Mar 2021 00:00:00 +0200

The aim of the work is to determine the spectrum and strenght of antimicrobial activity of the studied compositions, to compare them with the activity of substancesand to select the most optimal concentration for further combination with each other.

Topicality. Nowadays, one of the most common skin diseases is acne and demodicosis, the manifestations of which can be mild (comedones in seborrheic areas), more noticeable (papules-pustular rash) and severe (large cyanotic infiltrative elements in the back, prone to abscessing and scarring). The prevalence of acne and demodicosis currently reaches 90%. With these skin pathologies, it is desirable to use safe and effective drugs for external therapy, which provide rapid improvement of the skin (reduction of inflammation without side effects) to obtain a rapid and high-quality therapeutic effect. In the course of our research, we selected 3 active pharmaceutical ingredients (APIs): metronidazole, benzyl benzoate and benzoyl peroxide - according to the purpose of ICD-10 and their effectiveness in these pathologies. Mild medicines have an advantage over dermatological diseases such as acne and demodicosis because the use of soft medicines is local, namely a targeted effect on the microbial microflora.

At present for production of soft medicines for local application such substances as macromolecular compounds are widely used, plasticizers, surfactants,etc. When creating a drug composition, a study was conducted aimed at obtaining soft medicines with certain consumer properties, in particular physicochemical (pH, osmotic activity, homogeneity,etc.) , physical and mechanical properties (rheological parameters).

Materials for the study – soft medicines based on cetyl alcohol, Emulgade Sucro Plus, Polyvinylpyrrolidone, Carboxymethylcellulose, Tween 80, Triethanolamine, Propylene glycol, vaseline oil, which as (API) contains metronidazole, benzoyl peroxide, benzylbenzene. The specific antimicrobial activity of the samples was tested in accordance with Order № 167 of the Ministry of Health of Ukraine dated 05.04.2007 by the standard macromethod of serial dilutions in liquid nutrient medium and by the method of diffusion into agar. The minimum inhibitory concentration (MIC) of API (substrates) was determined.

Results. The studied compositions of soft medicines and substrates revealed to presence of antibacterial (bacteriostatic) action against the test strains of microorganisms.

Conclusions. The test of the compositions of soft medicines and the substance revealed the presence of a slight antibacterial (bacteriostatic) effect against the test strains of microorganisms.
