Common Medications May Have Hidden Risks in Pregnancy, Doctors Warn
Summary
A new review suggests that some common medications used during pregnancy may affect cholesterol production in the developing fetal brain. Although cholesterol is important for brain growth, experts say there is no clear proof that these medications harm children's brain development.Key Facts
- The review was published in the Journal of Clinical Investigation by researchers from the University of Nebraska Medical Center.
- Medications such as certain antipsychotics, antidepressants, beta blockers, and cholesterol-lowering drugs may disrupt cholesterol production in the fetal brain.
- Cholesterol is crucial for nerve growth and the formation of protective coverings around nerve fibers during brain development.
- Some drugs called sterol biosynthesis-inhibiting medications (SBIMs) can cause a buildup of a cholesterol precursor called 7-dehydrocholesterol (7-DHC).
- The buildup of 7-DHC can lead to toxic byproducts (oxysterols) that might harm developing brain tissue.
- Genetic disorders affecting cholesterol production can cause severe brain development problems, which some medications might partially mimic.
- Experts advise pregnant women to continue prescribed treatments, as untreated health issues can also pose risks to pregnancy and the baby.
- More research is needed to understand if these medication effects in the lab also happen in humans during pregnancy.
