Imagine a tiny, fragile newborn fighting for every breath, their delicate heart struggling with a condition called patent ductus arteriosus (PDA). This life-threatening issue affects many preterm infants, and the debate over the best treatment has raged for years. But a groundbreaking study just shook things up, suggesting a surprising alternative to the standard medication. Here’s the scoop: a recent trial published in Frontiers in Pediatrics compared paracetamol (yes, the common pain reliever) to ibuprofen for treating hemodynamically significant PDA (hsPDA) in preterm babies. And the results? They’re turning heads. [Link to study: https://www.frontiersin.org/journals/pediatrics/articles/10.3389/fped.2025.1717284/full]
But here’s where it gets controversial: while ibuprofen has long been the go-to treatment in the UK, this small yet rigorous trial hints that paracetamol might be just as effective—and equally safe. The study, known as the Paracetamol and Ibuprofen Research (PAIR) trial, found no significant differences in adverse effects, complications, or PDA closure rates between the two drugs. However, don’t start swapping medications just yet—the study wasn’t designed to prove superiority or equivalence, and its small size means larger trials are desperately needed.

And this is the part most people miss: PDA is more than just a medical term. It’s a condition where a blood vessel that should close after birth remains open, causing abnormal blood flow between the heart and lungs. This can lead to strained organs, poor circulation, and breathing difficulties—a terrifying reality for already vulnerable preterm infants. While ibuprofen is the established treatment, paracetamol’s off-label use in neonatal intensive care units (NICUs) has been quietly growing, despite lingering questions about its effectiveness and safety.
The PAIR trial, conducted in a UK NICU, enrolled 32 preterm infants with hsPDA, randomly assigning them to receive either paracetamol or ibuprofen. Treatment protocols were carefully designed, with paracetamol given as an initial 20 mg/kg dose followed by maintenance doses, and ibuprofen administered over three days. Outcomes were measured through echocardiograms and assessments of complications like necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), and bronchopulmonary dysplasia (BPD).
Here’s the kicker: while paracetamol showed slightly higher PDA closure rates (25% vs. 12.5% for ibuprofen), the difference wasn’t statistically significant. Both drugs had similar safety profiles, with only minor adverse effects. But the study’s real value lies in its feasibility—it proved that a larger, multicenter trial is not only possible but necessary.
So, what does this mean for neonatal care? The PAIR trial opens the door to a potentially game-changing alternative for hsPDA treatment, but it also raises questions. Is paracetamol truly a viable option, or are we jumping the gun? And what about long-term outcomes, which this study didn’t address? We want to hear from you: Do you think paracetamol could replace ibuprofen in PDA treatment, or is more research needed? Share your thoughts in the comments!
For now, one thing is clear: this study is a crucial step forward, but it’s just the beginning. Larger trials are essential to guide clinical practice and ensure the best possible care for these tiny fighters. [Journal reference: Mukherjee, A., et al. (2026). Frontiers in Pediatrics, 13.
