Avana 100 mg (often sold under brand names like Avana 100 mg or similar) is a medication used to treat erectile dysfunction (ED) in adult men. Avanafil belongs to a group of medicines called PDE5 inhibitors, which work by improving blood flow to the penis during sexual stimulation. When a man becomes sexually aroused, the body releases nitric oxide, which increases a chemical called cGMP. This chemical relaxes blood vessels in the penis, allowing more blood to flow in and helping produce an erection. Avanafil works by blocking the PDE5 enzyme that breaks down cGMP, thereby enhancing and prolonging this natural process.
