title: Teratogenic potential of two neurotropic drugs, haloperidol and dextromoramide, tested on mouse embryos.
abstract: Potential teratogenic activity of two neurotropic drugs, haloperidol and dextromoramide tartrate, was tested by using the mouse embryo experimental model. Like numerous other drugs of this class these two are also embryotoxic. After treatment 1 hour into the 9th gestation day they induce the neurotropic syndrome of malformations comprising exencephaly, craniorachischisis, kinking of the spinal cord, brachyury, and dilation of the fourth brain ventricle. In addition, dextromoramide tartrate was found to induce one more, so far unknown, neural tube defect, namely the ectopia of the neural tube. Delay of treatment by 1 or 2 hours tends to displace the location of the neural tube defects along the length of the neural axis towards the anterior and posterior directions. Even after accumulating these results at relatively high doses, it is difficult to estimate human reproductive risks from this animal data for human therapeutic doses.
