Ibuprofen vs. indomethacin for persistent ductus arteriosus closure in preterm infants
Abstract
Background Indomethacin and ibuprofen are anti-prostaglandinE2 agents administered for persistent ductus arteriosus (PDA)
closure. Ibuprofen has weaker cyclooxygenase-1 inhibitor affinity
than that of indomethacin, causes decreased gastrointestinal
circulation, as well as brain and kidney side effects.
Objective To compare the efficacy of oral ibuprofen and
indomethacin for PDA closure in preterm infants.
Methods A randomized double-blind controlled trial on preterm
infants with PDA was performed in Moehammad Hoesin
Hospital, Palembang, from October to December 2011. Persistent
ductus arteriosus was diagnosed by echocardiography. Subjects
were divided into two groups, and received either ibuprofen or
indomethacin. Ibuprofen was given at a dose of 10 mg/kgBW /d
on day 1 and 5 mg/kgBW /d on days 2 and 3. Indomethacin was
given in three doses over 24 hour-intervals; the first dose was 0.2
mg/kg, and the second and third doses were 0.1 mg/kg each.
Results Sixty infants were enrolled in this study, 36 boys (60%)
and 24 girls ( 40%). Fifty-two subjects completed the study protocol.
Ductus arteriosus (DA) closure after treatment was observed in 22
out of 26 subjects in the ibuprofen group and 19 out of 26 subjects
in the indomethacin group (P= 0.04). The mean DA diameter
reductions after administration of ibuprofen or indomethacin were
0.40 (SD 0.16) mm and 0.30 (SD 0.21) mm, respectively (95%CI
of differences0.05 to0.17; P= 0.04). Serum creatinine was elevated
in the indomethacin group following treatment compared to the
ibuprofen group [P = 0.002, 95% CI of differences 0.06 to 0.27].
Ductus arteriosus reopening occurred in 4 out of 19 subjects in the
indomethacin group, while n one in the ibuprofen group .
Conclusions Ibuprofen is better than indomethacin, in terms of
higher PDA closure rate and mean DA diameter reduction after
treatment. In additional, indomethacin has significantly greater
increase in mean serum creatinine level after treatment than
ibuprofen.
