Avana 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Avanafil, which belongs to a class of drugs known as PDE5 inhibitors (phosphodiesterase type 5 inhibitors). Avanafil works by increasing blood flow to the penis during sexual arousal, helping men achieve and maintain an erection. Avanafil, the active ingredient in Avana 100 mg, works by inhibiting the enzyme PDE5, which breaks down cyclic GMP. Cyclic GMP helps to relax the smooth muscles in the blood vessels of the penis, increasing blood flow during sexual stimulation. https://www.flatmeds.com/product/avana-100-mg/
