Abstract : Carbenoxolone sodium, sodium 3β-hydroxy-11-oxo-12-oleanen-30-oate sodium succinate, has been developed as a peptic ulcer agent. This study was undertaken to investigate its teratogenicity. Carbenoxolone sodium, dissolved in saline solution, was given to male and female mice before mating and on early pregnancy at the doses of 50, 100 and 200mg/kg/day and the effects on dams, fetuses and pregnancy rate were evaluated. 1) Carbenoxolone did not affect maternal body weight gain, survival rate of fetus, fetus sex ratio and fetus body weight. 2) There were no teratogenicity and no embryo resorption effects in carbenoxolone and it did not accelerate abnormal ossification. 3) Only partial retarded ossification was observed in fetuses born by the mating group with the highest dosage. (200mg/kg/day was given male and female mice before mating.) 4) No influence was observed in mating rate and pregnancy rate It is concluded from the present study carbenoxolone sodium given to male and female mice before mating and in early pregnancy stage does not affect their fetuses.
