Abstract


This article presents the results of the experimental research on the acute toxicity of the pharmaceutical substance of the drug Rapitalam, which is a modulator of metabotropic glutamate receptors. The study was conducted at the center for preclinical studies, Belgorod National Research University. Acute toxicity was studied on non-linear white mice-males weighing 18–22 g. All mice were divided into two groups—experimental and control. To determine the median lethal dose of the solution the test drug was administered to the mice one time intragastrically at doses of 1600, 1800, 2000, 2200 and 2400 mg/kg. The control group animals were given an equivalent amount of the solvent used to prepare the solution of the studied drug. The research has shown a good tolerability of the drug doses several times exceeding the therapeutic dose. According to K.K. Sidorov’s classification, pharmaceutical substance of the drug Rapitalam should be attributed to low-toxic drugs.
