What is Alprostadil?
Alprostadil injection 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.
1.Alprostadil is used in maintaining a patent ductus arteriosus in newborns.
2. Alprostadil is also as urethral suppositories and in injectable form.
3.Alprostadil is also used for critical limb ischemia.
