Avana 50 mg is a prescription medicine used to treat erectile dysfunction (ED) in adult men. It contains avanafil, a phosphodiesterase type 5 (PDE5) inhibitor that helps improve blood flow to the penis during sexual stimulation. Avanafil works by blocking the PDE5 enzyme, which normally restricts blood vessel relaxation. When this enzyme is inhibited, blood vessels in the penis relax and widen, allowing increased blood flow. This helps achieve and maintain an erection, but only when there is sexual arousal. It does not increase sexual desire.
