Avanafil Drug Information

Medication Information: Erectile dysfunction (sometimes called impotence) means that you can not maintain a proper erection. There are several causes for this problem, one of which is narrowing of the arteries, which prevents blood from reaching the penis.

Avanafil works by blocking the action of a chemical in the body called type 5 phosphodiesterase. As a result, the blood vessels dilate and after sexual arousal, blood flow to the penis improves.

Avanafil is prescribed only for men with erectile dysfunction due to a specific disease, and you can buy Avanafil only with a prescription.
