Summary

This study is collecting blood and other samples from 5,000 children and young adults (under 21) who are already taking certain medications as part of their regular care. The goal is to understand how these drugs move through and affect children's bodies, so doctors can prescribe the safest and most effective doses. The study covers many conditions, from COVID-19 to heart failure, and includes drugs like antibiotics, pain relievers, and heart medications.
