Toxicological parameters of the drug based on Ornidazole and Levamisole hydrochloride

The purpose of the research is the study of pharmaco-toxicological properties of the Ornidazole- and Levamisole hydrochloride-based drug.Materials and methods. The pharmaco-toxicological properties of the Ornidazole- and Levamisole hydrochloride-based drug were studied in the premises of the Laboratory of Preclinical Studies, Faculty of Veterinary Medicine, Stavropol State Agrarian University. Acute and chronic toxicity, and irritant effect of the drug was studied under the Guidelines for Preclinical Studies of Drugs (2012). Hematological studies of laboratory animals were performed with an automatic hematological analyzer, and biochemical studies of the blood serum were done with an automatic biochemical analyzer.Results and discussion. It has been found that the Ornidazole- and Levamisole hydrochloride-based drug belongs to the Hazard Class 3 for the median lethal oral dose in accordance with GOST 12.1.007–76 as moderately hazardous substances; it does not have a pronounced subchronic toxicity or irritant effect. Multiple use of the active substance for 14 days does not cause significant changes in the clinical condition, or in hematological and biochemical profile of laboratory animals.
