STUDY OF THE QUALIT Y OF PHARMACEUTICAL INFORMATION FOR PATIENTS FROM THE PERSPECTIVE OFTHE PROPER USE OF ANTI-ASTHMATIC DRUGS

RELEVANCE. Bronchial asthma, along with cardiovascular and oncological diseases, is one of the three most common chronic non- communicable diseases. For the most part, anti-asthmatic drugs (LP) are presented in the form of aerosols, powders, solutions for inhalation and other dosage forms intended for administration directly into the human respiratory tract. It is obvious that misunderstanding of the method of application and / or insufficient effectiveness of LP due to improper use can lead to a decrease in patients’ adherence to the prescribed therapy. In this regard, the availability of pharmaceutical information in the instructions becomes important, i.e. the more accessible the information in the instructions is to the patient, the higher the probability of proper use of the drug, maintaining patient compliance and preserving the patient’s quality of life. PURPOSE. The aim of the study was to analyze the completeness of pharmaceutical information provided in the instructions for the medical use of anti-asthmatic drugs (LP) and on the websites of manufacturing companies, from the standpoint of patients’ compliance with the rules for the use of LP. The main objectives of the analysis were: identification of the proportion of anti- asthmatic drugs that have a detailed scheme of use in the instructions; analysis of the instructions of anti-asthmatic drugs from the position of having indications of additional features of the use / use of drugs; analysis of instructions for anti-asthmatic drugs, the use of which is possible for groups of patients with physical or cognitive disabilities; identification of the share of companies producing anti-asthmatic drugs that support patients by conducting a specialized consulting service on the use of drugs. METHODS. The assessment of the quality of pharmaceutical information for patients was carried out on the basis of an analysis of 165 instructions for the medical use of pharmacotherapeutic groups of drugs designated in GINA-2021 (Global Initiative for Asthma-2021) and Federal Clinical Guidelines for the Treatment of Bronchial Asthma of the Russian Respiratory Society (2019) as anti-asthmatic drugs. The analysis was also carried out in relation to the information content of the websites of anti-asthmatic LP manufacturers, additionally, by creating a direct search query, the presence of a private page on the Internet for specific LP was determined. In the course of the research, methods of logical, comparative analysis, as well as generalization and grouping were used. To process the results obtained, the Excel computer program of the Microsoft Office 10 package was used. RESULTS. As a result of the analysis, it was revealed that the vast majority of anti-asthmatic drugs of all the studied pharmacotherapeutic groups are intended for administration directly into the respiratory tract, the article presents the results of a study on the ratio of inhaled and non-inhaled dosage forms in the context of the analyzed pharmacotherapeutic groups. The article presents data on the proportion of anti-asthmatic drugs that have a detailed description in the instructions in addition to the standard method of application (figure, diagram, pictogram) the method of introduction / use of LP. The fact of the absence of a detailed method of application in the instructions of various pharmacotherapeutic groups has been established. The results of the analysis of the number of instructions with the additional properties of LP indicated in them, allowing the use of LP data in patients with physical or cognitive characteristics (limitations), are presented. The number of companies producing anti-asthmatic drugs that have posted detailed information for consumers regarding the use of these drugs on their websites, as well as the number of drugs that have their own website, has been revealed. CONCLUSION. The information in the instructions for the medical use of anti-asthmatic drugs and on the official websites of the manufacturing companies (holders of registration certificates) of the studied drugs is not always exhaustive in terms of the use of inhaled dosage forms, which does not fully ensure the safe and effective receipt of anti-asthmatic pharmacotherapy. According to the authors, improving the quality of information for patients about the rules of using drugs for the treatment of bronchial asthma will simplify the use of dosage forms specific for its therapy, increase patients’ adherence to prescribed pharmacotherapy, reduce the risks from insufficient effectiveness of anti-asthmatic pharmacotherapy and preserve the quality of life of patients associated with the disease.
