Pregnant Sprague-Dawley rats were treated with 0, 150 or 200 mg/kg valproic acid by gavage (VPA) on days 7-18 of gestation. These doses produced no maternal toxicity, reproductive effects or effects on offspring growth and survival. Maternal plasma VPA peak levels averaged 99 and 134 micrograms/ml 1
Pharmacokinetic studies were performed in connection with culture experiments. Using the technique of cultivating whole rat embryos of the early postimplantation stage, we measured the concentration of valproic acid (VPA) and 2-en-VPA in the culture medium (free and protein-bound form) and in embryo
