toxic effects of drugs on the fetus

reaction of the fetus depends on the effects of drugs:

  • of gestational age and the stage of fetal development at the time of treatment;
  • penetration rate of the drug through the placenta from mother to fetus;
  • on the characteristics of the exchange of the drug to the mother, the fetus and placenta.

decisive role here, of course, belongs to the stage of fetal development.Most sensitive to the damaging effects of drugs has the embryo in the first 3 months of development.During this period, drugs can cause malformations of organs and tissues (teratogenic effects), and the death of the embryo (fetotoxic effects).If a drug has teratogenic, pregnant woman gets in a short amount of time, then this is reflected in the structure of the body, the tab is going at the moment of taking the medicine.If a woman gets a drug for a long time, the result will be the emergence of multiple malformations.

But after the first three months of pregnancy can not exclude the negative impact of drugs on the fetus.The reaction of the fetus during this period depends on which body is currently in the development stage (in this period developed eyes, ears, teeth, external genitalia, and the central nervous system).

impact of drugs on the fetus can be done not only through the placenta, but also by the penetration of the drug through the membranes in the amniotic fluid that the fetus absorbs.Some drugs (mainly antibiotics) have an increased ability to accumulate in the amniotic fluid - the effect is used in the treatment of intrauterine infection.

drugs have varying degrees of adverse effects on the fetus.

fetal effects of some other drugs

negative impact on the fetus non-steroidal anti-inflammatory drugs, especially acetylsalicylic acid (aspirin) and indomethacin, they can cause abnormal development of the skeleton, the splitting of the hard palate (cleft palate), and so on.
