Generic Name: Indomethacin
Product Name: Indocid PDA

Indication

Patent ductus arteriosus (PDA) in premature infants when usual medical management (eg. fluid restriction, diuretics, digitalis, respiratory support) is ineffective.The drug should only be used in a hospital under supervision.

Action

Exact mechanism of action is not known, but it is believed to be a potent inhibitor of prostaglandin synthesis.In human newborns with certain congenital heart malformations, PGE2 dilates ductus arteriosus.

Dose advice

Dosage depends on the age of the infant at time of therapy.Therapy is defined as three intravenous doses of Indocid PDA given at 12 to 24 hour intervals, with careful attention to urinary output.

  • If age is < 48 hours: first dose is 0.2 mg/kg, second dose is 0.1 mg/kg and third dose is 0.1 mg/kg.
  • If age is 2 to 7 days: first dose is 0.2 mg/kg, second dose is 0.2 mg/kg and third dose is 0.2 mg/kg.
  • If age is > 7 days: first dose is 0.2 mg/kg, second dose is 0.25 mg/kg and third dose is 0.25 mg/kg.

Studies have found that indomethacin has a greater effect in reducing mortality and bronchopulmonary dyaplasia when given at two to three days rather than seven to ten days.
