Dosages

Closing a ductus arteriosus
  • Intravenous
    • Gestational age < 37 weeks
      [5] [6]
      • Postnatal age < 72 hours 
        Day 1: 10 mg/kg birthweight in 1 dose
        Day 2:   5 mg/kg birthweight in 1 dose
        Day 3:   5 mg/kg birthweight in 1 dose
        Postnatal age 72-108 hours
        Day 1: 14 mg/kg birthweight in 1 dose
        Day 2:   7 mg/kg birthweight in 1 dose
        Day 3:   7 mg/kg birthweight in 1 dose
        Postnatal age ≥108 hours
        Day 1: 18 mg/kg birthweight * in 1 dose
        Day 2:   9 mg/kg birthweight * in 1 dose
        Day 3:   9 mg/kg birthweight * in 1 dose

        *Indien het huidige gewicht al hoger is dan het geboortegewicht dient de dosering op basis het huidige gewicht berekend te worden.

        • If the ductus arteriosis has not closed after day 3, a second course may be given immediately afterwards based on the postnatal age at that time. The day 1 dose should then be the same as the day 2 and 3 doses.
        • If the ductus arteriosus has not closed or reopened at 48 hours after the last injection, a second course can be administered in the same manner. Give the second course based on the postnatal age at that time, including the double dose on day 1.
  • Oral
    • Gestational age < 37 weeks
      [2] [5] [6] [8] [9]
      • Postnatal age < 72 hours 
        Day 1: 10 mg/kg birthweight in 1 dose
        Day 2:   5 mg/kg birthweight in 1 dose
        Day 3:   5 mg/kg birthweight in 1 dose
        Postnatal age 72-108 hours
        Day 1: 14 mg/kg birthweight in 1 dose
        Day 2:   7 mg/kg birthweight in 1 dose
        Day 3:   7 mg/kg birthweight in 1 dose
        Postnatal age ≥108 hours

        Day 2:   9 mg/kg birthweight * in 1 dose
        Day 3:   9 mg/kg birthweight * in 1 dose

Renal impaiment in children > 3 months

No information available on dose adjustment in renal impairment.

Side effects in children

Very common (> 10%): neutropenia, thrombocytopenia, elevated serum creatinine, decreased sodium. Bronchopulmonary dysplasia.

Common (1-10%): intraventricular hemorrhage, periventricular leukomalacia. Pulmonary hemorrhage. Necrotizing enterocolitis, intestinal perforation. Oliguria, fluid retention, hematuria.

Occasionally (0.1-1%): hypoxemia. Gastrointestinal hemorrhage. Acute renal failure.

Further reported: pulmonary hypertension.

The complete list of all contra-indications can be found in the national Summary of Product Characteristics (SmPC) – click here

Contra-indications in children

  • Life-threatening infection;
  • Active bleeding, especially intracranial or gastrointestinal hemorrhage;
  • Thrombocytopenia (<50 x 10^9/l) or coagulation disorder;
  • Severe renal insufficiency;
  • Congenital heart disease in which the ductus arteriosus must remain open for satisfactory pulmonary or systemic blood flow (e.g., severe tetralogy of Fallot, severe coarctation of the aorta);
  • Known or suspected necrotizing enterocolitis.

Warnings & precautions in children

Do not use prophylactically in any pregnancy. Do not use in infants with markedly elevated bilirubin concentrations. When used in preterm infants after less than 27 weeks of gestation, efficacy was found to be limited (ductus arteriosus closure rate low (33-50%)) at the recommended dose.

Before administering ibuprofen, perform adequate echocardiographic examination to confirm a hemodynamically significant open ductus arteriosus and to exclude pulmonary hypertension and ductal-dependent heart disease.

Because of possible inhibition of platelet aggregation by ibuprofen, observe the newborn for signs of bleeding.

If hypoxemia occurs, closely monitor pulmonary arterial pressure.

If oliguria occurs with subsequent administration, wait until urine output has returned to normal levels.

Ibuprofen can mask signs of infection

Ibuprofen is metabolized primarily by CYP2C8 and CYP2C9. CYP2C polymorphisms do not affect the action of ibuprofen in closing the ductus arteriosus.
