Compliance with ethical standards: the study was carried out in compliance with all ethical standards recommended in the Russian Federation. Rats were selected as a test system, as animals with a minimum set of characteristics that make it possible to conduct an experiment: a sufficient size of paws for convenient measurements and possibility of taking the volume of blood necessary for the study. The animals were kept in cages of sufficient area and with timely bedding change (2 times a week). Animals are provided with free access to water and food, a 12-hour lighting cycle, optimal temperature and humidity, and supervision by a licensed veterinarian. Although the research protocol did not allow to use painkillers that could distort the results of experiments, all procedures were carried out by qualified and experienced personnel, which ensured minimization of stress and pain. The animal study was preceded by in vitro studies of the drug. The power of the statistical tests used was evaluated, which made it possible to form samples of an optimal size. The animal study was approved by the Independent Ethical Committee of the Federal State Budgetary Educational Institution of Higher Education Yaroslavl State Medical University of the Ministry of Health of the Russian Federation, Protocol No. 6 dated 09/14/2023.
