[Effect of fosfomycin-calcium on reproductive performance of rats. III. Peri- and post-natal examination (author's transl)].
The peri- and post-natal examination of fosfomycin-Ca (FOM-Ca) was undertaken in Wistar strain rats. Rats were treated orally at dose levels of 140, 1,400 and 2,800 mg/kg/day from the 14th day of gestation to 21st day after delivery. One-third of pregnant rats in each group were sacrificed on 20th day of gestation and then their fetuses were examined for external, visceral and skeletal observation. The remaining mothers were allowed to deliver naturally, and then their offsprings were examined for postnatal development. No effect of FOM-Ca treatment to rat mothers was found except soft stool was seen in 1,400 and 2,800 mg/kg groups. No effect of FOM-Ca on rat fetuses and newborns was found except fetal body weight and survival rate decreased and skeletal variation increased in maximum dose. Consequently, it can be concluded that FOM-Ca has no effect on rat mothers, fetuses, and newborns treated during peri- and post-natal period.
