Avana 100 mg is a medication primarily used to treat erectile dysfunction (ED). It contains Avanafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Avanafil works by relaxing blood vessels in the penis, which increases blood flow and helps achieve an erection when sexually stimulated. It specifically targets the PDE5 enzyme, making it effective for ED treatment .
