Usual Pediatric Dose for Patent Ductus Arteriosus

Less than 12 Months:
Initial dose: 0.05 to 0.1 mcg/kg/min continuous IV infusion
Maintenance dose: 0.01 to 0.4 mcg/kg/min continuous IV infusion

-The preferred route is continuous IV infusion into a large vein; may also be administered through an umbilical artery catheter placed at the ductal opening.
-Once a therapeutic response is achieved (increased partial oxygen pressure in patients with restricted pulmonary blood flow or increased systemic blood pressure and blood pH in patients with restricted systemic blood flow), reduce the infusion rate to the lowest dose that maintains the desired response.
-If response to initial dose is inadequate, dosage can be increased up to 0.4 mcg/kg/min. However, in general, higher infusion rates do not produce greater effects.

Use: Palliative, not definitive, therapy to temporarily maintain ductus arteriosus patency until corrective or palliative surgery can be performed in neonates with congenital heart defects who depend upon the patent ductus for survival. Such congenital heart defects include pulmonary atresia, pulmonary stenosis, tricuspid atresia, tetralogy of Fallot, aortic arch interruption, aorta coarctation, or transposition of the great vessels with or without other defects.

Alprostadil Pregnancy Warnings

AU TGA pregnancy category: Not formally assigned to a pregnancy category US FDA pregnancy category: C (suppositories) US FDA pregnancy category: Not formally assigned to a pregnancy category (non-suppository formulations) Comments: Male partners should use a condom during intercourse.

Animal studies have revealed evidence of embryotoxicity. There are no controlled data in human pregnancy. This drug is chemically identical to prostaglandin E1 (PGE1), which occurs naturally in seminal fluid. Use of this drug may add to the amount of PGE1 present in the seminal fluid. Male partners should use a condom during intercourse to avoid vaginal irritation and risk of preterm delivery. US FDA pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
