Interventions
- DrugQuercetin
Quercetin (3, 30, 40, 5, 7-pentahydroxyflavone) is a naturally occurring antioxidant that belongs to a group of polyphenolic compounds known as flavonoids. Quercetin is routinely available as an over-the-counter product due to it being a nutritional supplement. However, for the purpose of the study, it will be purchased in the powder form from PCCA (supplied as 96% quercetin dihydrate) and stored and distributed by the investigational pharmacy at CCHMC using standard operational procedures. Quercetin is administered as an oral medication, supplied in powder form. Quercetin will be stored at room temperature. The product will be dispensed for home administration. Each packet will be labeled in accordance with applicable regulatory requirements. Patients or parents will be instructed to mix it with a small amount of yogurt or other preferred food for ingestion.
