How antiviral medicines affect hormones in pregnant people, fetuses, and newborns

Understanding the underlying toxicological mechanisms of drug-hormone interactions to improve the safety profile of antiviral medications in pregnant people, developing fetuses, and neonates

NIH-funded research University of Colorado Denver · NIH-11248398

Researchers are looking at how antiviral drugs can change hormone balance during pregnancy and in newborns so these medicines can be used more safely.

What this research studies

This project focuses on how antiviral drugs can disturb steroid hormones that are important in pregnancy and early life. The team will study liver enzymes that handle both drugs and hormones (for example CYP and UGT enzymes) and measure drug and hormone levels in laboratory tests and biological samples. They will use a mix of lab models and human-derived samples to trace the toxicological steps that lead to hormone disruption and newborn problems. Results will aim to pinpoint which drugs or conditions raise risk and to guide safer use of antivirals in pregnant people and infants.

Who could benefit from this research

Good fit: Pregnant people who are taking or may need antiviral medications and newborns exposed to those antivirals would be the most relevant candidates for related sample collections or clinical components.

Not a fit: People who are not pregnant and who are not receiving antiviral therapy are unlikely to gain direct benefit from this specific research.

Why it matters

Potential benefit: If successful, the work could lower the risk of hormone-related side effects from antivirals in pregnant people and their babies and help doctors choose safer treatments.

How similar studies have performed: Prior reports have linked some antivirals to hormone changes and neonatal issues, but directly mapping the enzyme-level drug–hormone mechanisms in pregnancy is relatively new.
