To compare the efficacy of intravenous ibuprofen at high (20-10-10 mg/kg/dose) and low doses (10-5-5 mg/kg/dose) the closure of patent ductus arteriosus in preterm newborns. A cohort study with historical control of newborns that received high- and low-dose intravenous ibuprofen, from 2010 to 2013 in a neonatal intensive care unit, for closure of the patent ductus arteriosus, documented by echocardiography. Secondary outcomes included the number of ibuprofen cycles, incidence of bronchopulmonary dysplasia, necrotizing enterocolitis, changes in renal function, and death. Seventy-seven patients received three doses of ibuprofen for the treatment of patent ductus arteriosus, with 33 receiving high-dose and 44 low-dose therapy. The ductus closed after the first cycle in 25 (56.8%) low-dose patients and in 17 (51.5%) high-dose patients (p > 0.99). Sixteen patients received a second cycle of ibuprofen, and the ductus closed in 50% after low-dose and in 60% after high-dose therapy (p > 0.99). Seven patients required surgery for ductus closure, 13.6% in the low-dose group and 3% in the high-dose group (p = 0.22). Thirty-nine patients developed bronchopulmonary dysplasia, 50% in the low-dose group and 51.5% in the high-dose group (p > 0.99). Twenty-two (50%) low-dose patients died vs. 15 (45.5%) high-dose patients (p = 0.86). There was no difference in closure of the ductus arteriosus or occurrence of adverse effects between the two dose regimens.
