N2 - Ibuprofen, a nonsteroidal antiinflammatory drug, widely used as antipyretic, antiinflammatory, and analgesic agent and for therapy of arthritis, exerts a dose-dependent constriction of the ductus arteriosus in newborn lambs. Two intravenous preparations, namely ibuprofen lysine and ibuprofen-THAM, have been studied in preterm newborns with patent ductus arteriosus. Clinical trials have compared IV ibuprofen to placebo, or to indomethacin. Pharmacodynamic effects of this drug before and after its administration have also been evaluated. Compared with placebo, IV ibuprofen effectively closed PDA with minimal effect on renal function. One study using intravenous ibuprofen-THAM showed decreased renal function and increased risk of NEC and PPHN. Compared with indomethacin, IV ibuprofen lysine exerted similar efficacy (75% to 93% closure). However, indomethacin increased abnormal renal function and decreased mesenteric and cerebral blood flow and bio-energetics. Two clinical trials showed that ibuprofen did not reduce the incidence of intraventricular hemorrhage compared with placebo. The drug has prolonged elimination (plasma half-life = ca 23 hours), suggesting that once daily dosing is appropriate. Dose finding studies indicate that a starting dose of 10 mg/kg followed by 5 mg/kg/d for 2 more days provides optimal efficacy with the least adverse effects. Neonatal data on ibuprofen and indomethacin indicate that, on the first day of life when IVH prevention is desired, indomethacin and not ibuprofen should be used since ibuprofen has no effect on IVH risk. On or after the second day of postnatal life, when early or therapeutic PDA closure is needed, ibuprofen and not indomethacin is probably the first choice due to its better adverse event profile.
