What is Avanafil?
Avanafil is a prescription medicine orally used to treat erectile dysfunction (ED) in men.
It belongs to a class of drugs called PDE5 inhibitors, like sildenafil (Viagra) and tadalafil (Cialis).
Avanafil tablet works by raising blood flow to the penis during sexual stimulation.
It is known for its fast onset, usually working within 15 to 30 minutes and helps you get hard erections.
The most common brand name for Avanafil is Stendra.
Always consult a doctor before use to ensure it’s safe and appropriate for you.
How Does Avanafil Work?
Avanafil works by blocking the enzyme phosphodiesterase type 5 (PDE5).
This enzyme breaks down a chemical called cGMP, which helps relax smooth muscles and improve blood flow in the penis.
By preserving cGMP, Avanafil allows better blood flow during sexual stimulation, leading to a firm erection.
It only works when you're sexually aroused and doesn’t cause an erection on its own.
