Low-dose aminophylline for the treatment of neonatal non-oliguric renal failure-case series and review of the literature.

Objective: Aminophylline is a methylxanthine with multiple physiologic actions. At low doses, aminophylline can antagonize adenosine and improve renal function via increased glomerular filtration rate. Despite its clinical use, little data exists in neonates for this indication.

Effect of age and birth weight on indomethacin pharmacodynamics in neonates treated for patent ductus arteriosus.

Objectives: To determine patent ductus arteriosus (PDA) closure rates, and indomethacin (INDO) toxicity rates in neonates dosed with INDO using an individualized pharmacokinetic/pharmacodynamic (PK/PD) dosing approach. In addition, develop PD curves evaluating dose-response and concentration-response relationships for closure and renal toxicity, especially in select subgroups historically known as "poor responders" (<1000 g and > or = 10 days postnatal age).

Design: Prospective, cohort study.
