Abstract
Background. Osteoporosis is one of the most common diseases, which, along with myocardial infarction, stroke, cancer, and sudden death, occupies a leading place in the structure of morbidity and mortality of the population. Postmenopausal women are most vulnerable and are approximately 4 times more likely to be affected than men (80 % of all patients), and osteoporosis-related fractures are responsible for a significant increase in morbidity, disability, and mortality, especially in the elderly.Objective. To study the acute toxicity of the new drug “Antiosteoporosis drug” (patent No. 02-04-16643/15-0 dated February 26, 2015) with a single intragastric administration to mature outbred rats of both sexes.Design and methods. The study was conducted on outbred rats of both sexes according to protocol OECD 420, GOST 32296-2013. The development of a toxic effect was concluded based on behavioral tests, clinical examinations, changes in body weight, the results of pathomorphological examination of organ tissue and biochemical parameters of blood and urine.Results. According to the results of the study, the tested drug was classified according to the active substance into category 5 according to the GHS classification (2000
