Avana 100 mg is a medication used primarily to treat erectile dysfunction (ED) in men. It contains Avanafil as the active ingredient, which belongs to a class of drugs known as PDE5 inhibitors. This medication helps men achieve and maintain an erection in response to sexual stimulation by improving blood flow to the penis. Avanafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down cyclic guanosine monophosphate (cGMP), a substance that is crucial for the relaxation of smooth muscles and the dilation of blood vessels in the penis.
