The acute toxicity test in mice showed that when the dose was equivalent to 291.8 times the clinical dose in adults, none of the 40 animals died and no abnormalities were observed during the observation period. The maximum tolerated dose of the drug to mice was oral. (MTD) greater than 75 g/kg body weight.
