This study aims to present the aspects of the efficacy and therapeutic safety of paracetamol versus ibuprofen in the treatment of PDA in premature newborns. A systematic review of the literature was carried out, following the recommendations of the PRISMA protocol, using the Medline, Pubmed, LILACS, and SciELO databases.

Eight randomized clinical trials (RCTs) were selected for analysis, resulting in a sample size of 781 newborns with PDA treated with acetaminophen or ibuprofen. The efficacy of acetaminophen for DA closure is comparable to ibuprofen.
