Alprostadil (Inside the urethra (urine tube))
Erectile Dysfunction Agent (About this – PubMed Health)
Uses of This Medicine
Alprostadil urethral suppository is used to treat men who have erectile dysfunction (also called sexual impotence). It belongs to a group of medicines called vasodilators that can increase blood flow by expanding blood vessels. This medicine causes an erection because it increases the blood flow to the penis.
Alprostadil should not be used as a sexual aid by men who do not have erectile dysfunction. If the medicine is not used properly, permanent damage to the penis and loss of the ability to have erections could result.
This medicine is available only with your doctor’s prescription.
