Preclinical studies of veterinary medicinal products are important and compulsory studies in the development of new dosage forms. The aim of preclinical research is to determine the toxic effect and therapeutic efficacy of the test substance-the future dosage form, its effect on the body's basic systems, as well as the identification of possible side effects. This work is part of the research on the development of the composition and technology of the veterinary drug - a solution for intramammary application, conventionally called "Argocide", intended for the treatment of mastitis in cattle. A study of the acute toxicity of the intramammary veterinary drug was carried out in experiments on white rats of both sexes, according to the requirements for potential medicines. The establishment of the value of the average lethal dose (LD50) of the veterinary drug "Argocide" with intramuscular single administration to white mature rats is impossible due to the absence of animal death even when the drug is administered at doses exceeding 5.0 ml/kg. This experiment allows the veterinary preparation "Argocide" to be classified as practically non-toxic compounds (V class). The analysis of the results of the conducted studies indicates the relative harmlessness of the potential drug for veterinary medicine and allows us to foresee that the "Argocide" preparation can be classified as low-risk substances, which justifies the expediency of its further study and introduction into practice.
