It’s the gold standard in injectable ED medications. Alprostadil is a well-tested and highly effective medication that increases blood flow into the penis, producing an erection.

How Does Alprostadil Work?

Prostaglandin Relaxes Smooth Muscle, Allowing for More Blood Flow

Alprostadil (Prostaglandin E1) binds to prostaglandin receptors, causing the blood vessels in the penis to dilate. This restricts outflow from the penis, ultimately causing the corpora cavernosum in the penis to fill with blood, producing an erection. This potent hormone-like substance works within about 5 to 20 minutes, and the effects can last for about an hour.
