What Is Avanafil?

Avanafil is the active ingredient in medicines used to treat erectile dysfunction in adult men. It belongs to the PDE5 inhibitor class. It helps men who have difficulty getting or keeping an erection adequate for sexual activity.

It is the generic equivalent of the originally branded medicine Spedra (also marketed as Stendra in some regions). Generic products include the Avana range (e.g. Avana 100).

How Does It Work?

Avanafil blocks the PDE5 enzyme so that cGMP can build up, relaxing the blood vessels of the penis and improving blood flow during sexual stimulation. Sexual arousal is needed. Avanafil is noted for its relatively fast onset, often beginning to work within around 15 to 30 minutes, with its effect typically lasting for a few hours.

How Is It Usually Taken?

Avanafil is taken by mouth shortly before planned sexual activity, at the dose advised by your doctor. It can be taken with or without food, though a heavy meal may slightly delay onset. No more than one dose should be taken in any 24-hour period.
