ABSTRACT
Background:
Approximately 15 percent of misoprostol-induced-abortions may not be successful, leading to in utero exposure to the drug and to the induction of a series of defects including central nervous system, limb and visceral defects. A commonproposal is that the drug causes disruption of the fetal vasculature leading to embryonic or fetal hypoxia.Aim:
To evaluate the teratogenicity of misoprostol using the rat post-implantation embryo culture. Material andMethods:
Rat embryos were collected at the beginning of organogenesis and cultured in rat serum containing misoprostol at concentrations of 200, 2,000 or 20,000 pg/ml. Functionality, morphology and morphometry parameters were evaluated.Results:
Misoprostol induced a dose-dependent embryotoxic effect causing a decrease in embryo viability and function (poor vascular development and survival) and morphometry (alterations in branchial arches, heart and cephalic portions of the neural tube, among others).Conclusions:
All the manifestations observed are indicative of the ability of misoprostol to directly induce developmental retardation and alterations.
