Documented Uses

• Alprostadil 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. It is also indicated for the treatment of erectile dysfunction due to neurogenic, vasculogenic, psychogenic, or mixed etiology, and as an adjunct to other diagnostic tests in the diagnosis of erectile dysfunction.
• Medicines administered to the neonate [c]
• Parenteral - General injections - IV: 0.5 mg per mL in alcohol
• Other specified congenital anomaly of great arteries including arterial duct
• Drugs or agents which antagonize or impair any mechanism leading to blood platelet aggregation, whether during the phases of activation and shape change or following the dense-granule release reaction and stimulation of the prostaglandin-thromboxane system.
• Drugs used to cause dilation of the blood vessels.
