Avana 200 mg is a higher dose of avanafil, a medication used to treat erectile dysfunction (ED). Avanafil, the active ingredient, is a phosphodiesterase type 5 (PDE5) inhibitor that helps improve blood flow to the penis, facilitating an erection in response to sexual stimulation. Avanafil inhibits the PDE5 enzyme, which leads to increased levels of cyclic guanosine monophosphate (cGMP). This helps relax the smooth muscles in the blood vessels of the penis, enhancing blood flow and supporting an erection.
