1 Extensive toxicological investigations of clobazam are summarized. 2 LD50 values after oral administration ranged from 100 mg/kg in the dog to 6000 mg/kg in the rat. 3 Long-term repeated dose studies have shown withdrawal effects in the dog and monkey (notably convulsions leading to death), similar to those known to occur with other benzodiazepines. 4 It is concluded that the overall safety and tolerability of clobazam have been demonstrated in the preclinical animal studies.
