An acute oral toxicity study has been conducted on MV31. The result of the study was:Acute oral toxicity is greater than 2000 mg/kg when tested according to OECD 423.
The acute oral toxicity of the test article was determined in Sprague
Dawley rats. The study was conducted in compliance
with OECD GLP (1999). The test method was based on
OECD Guideline 423 (1996) and EC Method B.1 (1996). Rats
(3/sex) were administered a single dose of 2000 mg/kg body weight of
undiluted test article by oral gavage. Body weights
(Days 1, 8, and 15) and clinical signs (twice daily) were recorded. No
moratlity occurred during the study, and body weight gain was not
impaired. On study Day 1, stilted gait was observed in
1 animal and a squatting posture in 2 animals. No
other clinical signs were observed in any other animals at any time
points. Based on the results of the study, the oral LD50 of the test
article is > 2000 mg/kg body weight.
