Fatty liver may alter statin effects in kids, study warns
NCT ID NCT04903223
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how liver fat changes the way the body processes rosuvastatin, a common cholesterol drug, in children aged 8 to 21. Researchers will give a single dose to 50 kids with high cholesterol and measure drug levels and response. The goal is to understand if fatty liver increases the risk of side effects or makes the drug less effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Rosuvastatin 10mg
- What this could lead to
- If successful, this could help doctors personalize statin doses for children with fatty liver, reducing risk of side effects or treatment failure.
- What could go wrong
- This is a small, early-phase study (50 participants) focused on understanding drug behavior, not testing a new treatment. Results may not apply to all children.
