- Conclusions:
- The acute median lethal oral dose (LD50) to rats of test material was demonstrated to be between 1000 and 1400 mg/kg bw in males and 961 mg/kg bw in females (883 - 1046 mg/kg bw, 95% of confidence limit).
- Executive summary:
The acute toxicity of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the Guidelines for Toxicity Studies of Drugs (Notification No. 2. of the First Evaluation and Registration Division, 1989.
During the study the test material was administered once orally to male and female SD rats, and its acute toxicity was assessed. In addition, its lethal dose was calculated.
The dose levels were set at 500, 700, 1000, 1400, and 2000 mg/kg for 5 males/group, and 700, 1000, 1400, and 2000 mg/kg for 5 females/group. The dosing volume was set at 10 mL/kg.
All animals in the 1400 mg/kg or higher groups died by Day 2. Three females in the 1000 mg/kg group died on the day after dosing. From the mortality, LD50 values were between 1000 and 1400 mg/kg in males and 961 mg/kg in females (883 - 1046 mg/kg, 95% of confidence limit).
In clinical observation, decreases in locomotor activity, crouching position, lateral position, cyanosis, and/or ataxic gait were observed in both sexes. Moreover, gasping, tiptoe gait, anemia, emaciation, and/or loose stool were observed in males.
Although decreases in body weight were observed in 1 male in the 1000 mg/kg group until 7 days after dosing, it recovered thereafter. The body weights of the other animals were increased constantly during the observation period.
Necropsy findings of dead animals were as follows: abnormal contents like tar in the stomach and/or small intestine, hemorrhage of the glandular stomach and/or small intestine, congestion of the adrenal, dark reddish change of the lung, dilatation of the urinary bladder, and bloody ascites. In necropsy at the end of recovery period, no abnormalities were observed.
Under the conditions of the study the acute median lethal oral dose (LD50) of the test material to rats was demonstrated to be between 1000 and 1400 mg/kg bw in males and 961 mg/kg bw in females (883 - 1046 mg/kg bw, 95% of confidence limit).
