Paracetamol versus ibuprofen for the treatment of patent ductus arteriosus in preterm neonates: a meta-analysis of randomized controlled trials.

<bold>Background: </bold>Paracetamol has been suggested as an effective treatment for patent ductus arteriosus (PDA). However, the comparative efficacy and safety between paracetamol and ibuprofen were not determined.<bold>Methods: </bold>A meta-analysis of randomized controlled trials (RCTs) was performed. Relevant studies were identified via database searching. A fixed or random effect model was applied depending on the extent of heterogeneity.<bold>Results: </bold>Five RCTs with 677 neonates were included. The efficacies for the primary (risk ratio [RR]: 1.03, p = .56) and overall PDA closure were comparable between the two medications (RR: 1.02, p = .62). Neonates of the two groups were comparable for the incidence of PDA complications, including necrotizing enterocolitis (RR: 0.86, p = .70), intraventricular hemorrhage (RR: 0.84, p = .55), bronchopulmonary dysplasia (RR: 0.69, p = .16), and retinopathy of prematurity (RR: 0.58, p = .15), and the risks of sepsis (RR = 0.88, p = .48) and death (RR: 1.45, p = .45) within hospitalization. However, treatment with paracetamol was associated with a trend of reduced risk of renal failure (RR: 0.20, p = .07), and a significantly reduced risk of gastrointestinal bleeding (RR: 0.28, p = .009).<bold>Conclusions: </bold>Paracetamol may confer comparable treatment efficacy for the closure of PDA as ibuprofen, although paracetamol is associated with lower risk of adverse events.
