Moclobemide - Animal Toxicology

Animal Toxicology

• Acute toxicity: The oral LD₅₀ values in mouse and rat are quite high, indicating a wide therapeutic index. LD₅₀ for mice is 730 mg/kg and for rats 1,300 mg/kg. In dogs doses in excess of 300 mg/kg led to vomiting, salivation, ataxia, and drowsiness.
• Chronic toxicity: In an 18-months-study in rats with 10 mg/kg no signs of chronic toxicity were noted, with 50 mg/kg and 250 mg/kg only a slight loss of weight, and with 250 mg/kg mildly elevated Alkaline phosphatase and Gamma-GT. Studies in dogs revealed no toxicity relevant for humans. No evidence for a possible hepatic or cardiovascular toxicity was found.
