Erectile Dysfunction and Alprostadil
Effect of Alprostadil on Erectile Dysfunction
There are two types of alprostadil:
- Transurethral alprostadil (MUSE)
- Intracavernosal alprostadil (Caverject, Edex)
Alprostadil acts directly on the blood vessels in the penis to cause an erection. It can be inserted into the urethra (urinary tube in the penis) with a special device or injected with a small needle. Erection occurs in 8-10 minutes and lasts 30-60 minutes. The injection is effective in about 65%-85% of users; the insert is effective in about 65%. The maximal number of injections per week is three.
