How Avanafil Works

Avanafil belongs to a class of drugs known as PDE5 inhibitors. It works by relaxing the blood vessels in the penis, allowing for increased blood flow.

This increased blood flow can help achieve and maintain an erection when combined with sexual stimulation.

The action of Avanafil specifically targets the enzyme phosphodiesterase type 5 (PDE5), which plays a role in regulating blood flow in the penis.
