Metabolism and Toxicity of Acetaminophen

Summary

The purpose of this study is to investigate how acetaminophen (APAP) is released into the urine and blood; to determine how the blood levels of acetaminophen and its breakdown products affect the preterm infant's health; to decrease adverse drug reactions; and to collect data on how the genetic make-up or characteristics affect how APAP is handled within the preterm infant. By taking several blood and urine samples during the study, we will be able to check the blood levels (called pharmacokinetics) of APAP in preterm babies.
