С. В. Акчурин In Russia, as in other countries around the world, the number of companion animals is increasing and the demand for veterinary services consequently. Increasing demand leads to the emergence of new services and goods, including medicines. The number of medicines used to treat small animals runs into the thousands. However, not all medicines are widely used in veterinary practice. The World Small Animal Veterinary Association (WSAVA), following the approach of the World Health Organisation, has introduced the practice of defining essential medicines to identify the most important medicines in veterinary medicine. This enables veterinarians to achieve an optimal level of expertise in the pharmacotherapy of the most common and important diseases of dogs and cats through self-education, and assists regulatory authorities in monitoring the supply of essential medicines to the veterinary industry, including the implementation of import substitution work, assist veterinary clinic managers in compiling a list of medicines that must be available, contribute to the quality of veterinary education, in particular by improving the quality of teaching the subject “Veterinary Pharmacology”. As part of the study, two lists of essential and complementary medicines for cats and dogs used in Russian veterinary practice were compiled with with the help of experts from the veterinary industry. The lists are divided into sections reflecting the main areas of veterinary pharmacotherapy.
