Treatment Summary
Alprostadil is a drug naturally produced by the body that causes blood vessels to widen, increasing the amount of blood flowing to certain areas. In infants, it is used to prevent closure of the ductus arteriosus, a blood vessel that helps to provide oxygen and nutrients to the fetus. In adults, it is used to treat erectile dysfunction due to a variety of causes.

How Alprostadil Affects Patients
Alprostadil (prostaglandin E1) is a natural substance that can widen the blood vessels and increase blood flow. In adults, this leads to increased blood flow in the penis, causing it to become stiff. In infants, it can help increase the amount of blood going to either the lungs or the rest of the body.
How Alprostadil works in the body
Alprostadil increases blood flow in infants in multiple ways. It prevents the closure of a blood vessel connecting the pulmonary artery and aorta, allowing blood to flow through it. It also relaxes the smooth muscle of the corpora cavernosa and cavernosal arteries, allowing more blood to enter the penis and causing it to swell and become rigid. These effects create increased pulmonary or systemic blood flow, increased oxygen supply to tissues, improved renal perfusion and increased systemic blood flow to the lower body.
