The first active ingredient, Avanafil, belongs to a class of drugs called PDE5 inhibitors (phosphodiesterase type 5 inhibitors). Avanafil works by relaxing the blood vessels in the penis, allowing for increased blood flow when a man is sexually aroused. This results in a firm and sustained erection, making it easier to engage in sexual activity. Avanafil is known for having a quick onset of action and typically starts working within 15-30 minutes of consumption. https://www.genericday.com/extra-super-avana.html
