Summary
High-dose ibuprofen effectively closes patent ductus arteriosus (PDA) in preterm infants without increasing adverse effects. This high-dose regimen offers a superior treatment option for managing PDA in premature neonates.
Area of Science:
- Neonatal medicine
- Pediatric cardiology
- Pharmacology
Background:
- Patent ductus arteriosus (PDA) is common in preterm infants, especially those with respiratory distress syndrome (RDS).
- Standard-dose ibuprofen is a common treatment, but its efficacy can be limited.
- The optimal ibuprofen dosage for PDA closure in extremely preterm infants remains under investigation.
Purpose of the Study:
- To compare the efficacy and safety of a high-dose ibuprofen regimen versus a standard-dose regimen for PDA closure.
- To determine if a higher dose of ibuprofen improves PDA closure rates without increasing adverse events in very preterm infants.
Main Methods:
- A randomized controlled trial involving 70 infants with gestational age <29 weeks and echocardiographic evidence of significant PDA.
- Infants were randomized to receive either a standard (10-5-5 mg/kg/day) or high-dose (20-10-10 mg/kg/day) course of ibuprofen.
- Echocardiography was used to assess PDA status and adverse effects.
Main Results:
- The high-dose ibuprofen group showed a significantly lower rate of persistent PDA (14%) compared to the standard-dose group (37%) (P = 0.03).
- No significant differences in adverse effects were observed between the standard-dose and high-dose ibuprofen treatment groups.
- The high-dose regimen demonstrated superior efficacy in achieving PDA closure.
Conclusions:
- A high-dose ibuprofen regimen is more effective than the standard-dose regimen for closing PDA in preterm infants <29 weeks gestation.
- The increased efficacy of high-dose ibuprofen does not appear to be associated with a higher rate of adverse effects.
- High-dose ibuprofen represents a potentially improved therapeutic strategy for managing PDA in this vulnerable population.

01:29Drug Dosing: Infants and Children
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
01:21Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
