Safety and Efficacy of an Optimized Ibuprofen Dosing Regimen Versus Standard Dosing for Pharmacologic Closure of Patent Ductus Arteriosus
The purpose of this study is to determine if increasing the ibuprofen dose will increase the
likelihood of closing the patent ductus arteriosus in premature babies.
likelihood of closing the patent ductus arteriosus in premature babies.
Failure to close the PDA in premature neonates in a timely fashion can lead to pulmonary
over-circulation and systemic under-circulation. The PDA often fails to close using
currently approved Ibuprofen dosing regimens, and surgical closure becomes necessary.
Ibuprofen clearance in premature neonates is significantly correlated with postnatal age,
increasing rapidly over time. Hirt et al. published and optimized dosing scheme for preterm
neonates based on pharmacokinetic and pharmacodynamic data. We aim to use this dosing
regimen in the clinical setting to determine if increased rates of pharmacologic PDA closure
can be achieved.
