The anti-inflammatory activity of ibuprofen may also be partly due to its ability to scavenge reactive oxygen species and reactive nitrogen species. We evaluated the interaction between oxidative status and the medical treatment of patent ductus arteriosus with two forms of ibuprofen.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951116000822_abs2\" sec-type=\"materialsandmethods\"><jats:title>Materials and methods<\/jats:title><jats:p>This study enrolled newborns of gestational age \u2a7d32 weeks, birth weight \u2a7d1500 g, and postnatal age 48\u201396 hours, who received either intravenous or oral ibuprofen to treat patent ductus arteriosus. Venous blood was sampled before ibuprofen treatment from each patient to determine antioxidant and oxidant concentrations. Secondary samples were collected 24 hours after the end of the treatment. Total oxidant status and total antioxidant capacity were measured using Erel\u2019s method.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951116000822_abs3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>This prospective randomised study enrolled 102 preterm infants with patent ductus arteriosus. The patent ductus arteriosus closure rate was significantly higher in the oral ibuprofen group (84.6 versus 62%) after the first course of treatment (p=0.011). No significant difference was found between the pre- and post-treatment total oxidant status and total antioxidant capacity in the groups.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951116000822_abs4\" sec-type=\"discussion\"><jats:title>Discussion<\/jats:title><jats:p>Ibuprofen treatment does not change the total oxidant status or total antioxidant capacity.
