Avaforce 50 mg contains Avanafil, a phosphodiesterase type‑5 (PDE5) inhibitor used to treat erectile dysfunction. This dose is often chosen for mild ED or first‑time users because it’s typically effective with fewer side effects and works relatively quickly—often within 15–30 minutes after intake. Avanafil increases blood flow to the penis during sexual arousal by relaxing smooth muscle in the blood vessels. This helps achieve and maintain an erection when sexually stimulated, but it won’t cause an erection on its own—sexual arousal is still needed.
