Prostaglandin Analog

Prostin VR Pediatric

Approved 16 Oct 1981InjectionInjectable

Indications

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

In infants with restricted pulmonary blood flow, the increase in blood oxygenation is inversely proportional to pretreatment pO 2 values; that is, patients with low pO 2 values respond best, and patients with pO 2 values of 40 torr or more usually have little response. PROSTIN VR PEDIATRIC should be administered only by trained personnel in facilities that provide pediatric intensive care.

Contraindications

None.

Warnings and precautions

See WARNING box. NOTE: PROSTIN VR PEDIATRIC Sterile Solution must be diluted before it is administered. See dilution instructions in DOSAGE AND ADMINISTRATION section. The administration of PROSTIN VR PEDIATRIC to neonates may result in gastric outlet obstruction secondary to antral hyperplasia. This effect appears to be related to duration of therapy and cumulative dose of the drug. Neonates receiving PROSTIN VR PEDIATRIC at recommended doses for more than 120 hours should be closely monitored for evidence of antral hyperplasia and gastric outlet obstruction.

PROSTIN VR PEDIATRIC should be infused for the shortest time and at the lowest dose that will produce the desired effects. The risks of long-term infusion of PROSTIN VR PEDIATRIC should be weighed against the possible benefits that critically ill infants may derive from its administration.
