In vivo study | Lenampicillin hydrochloride (KBT-1585)(oral adminstration; 0-1000 mg/kg) does not lead to death in dogs, and maximum dose of in this acute toxicity study is recorded because of causing emesis.Lenampicillin hydrochloride (LAPC) are identified for it main metabolites in rat and dogs. The main metabolite in peripheral plasma is 2,3-butanediol in rats and dog, On the other hand, high levels of acetoin is found in portal plasma for early period after dosing of LAPC. These results shows that the biotransformation of promoiety in LAPC to acetoin carried out mainly in intestinal tissues, but acetoin is converted to 2,3-butanediol in liver. |
Toxicity | LD50 in male, female rats, male, female mice (mg/kg): approx 10000, approx 10000, 8294, 8492 orally; 4362, 4471, 3576, 4284 s.c.; 876, 838, 711, 775 i.v.; in dogs (mg/kg): >300 orally (Ogino) |
