SSRI use during pregnancy: effects on placental blood flow and inflammation

Official title: Use of SSRI during pregnancy on placental blood flow and the inflammatory response

Funded at University of Wisconsin-Madison · NIH-11608163 · Data updated 2026-11-12

This grant studies how antidepressants (SSRIs) used during pregnancy might affect the placenta and inflammation, and whether a 5-HT2 receptor blocker could mitigate any negative effects.

Who could benefit from this research

Could help

Pregnant people currently taking or considering SSRI treatment and their clinicians may benefit from the findings.

Less likely to help

People not pregnant or not using SSRIs may not directly benefit from this research.

What this research studies

If you are pregnant and taking an SSRI, this research looks at whether the drug changes how blood flows through the placenta and increases placental cell death and inflammation. The team will test whether blocking 5-HT2 receptors with ketanserin can reverse these potential effects. They will explore which serotonin receptor subtypes are involved and use a human immune and endothelial cell analysis framework to understand immune and vascular changes in the placenta. The goal is to define risks specific to SSRIs during pregnancy and identify strategies to protect fetal development.

Why it matters

Potential benefit: It could clarify SSRI-associated placental risks and point toward strategies to reduce adverse pregnancy outcomes for mothers and babies.

How similar studies have gone: Previous work has begun to map placenta responses to SSRIs, but this project aims to define mechanisms and mitigation strategies with human relevance.
