Avana 50 mg is a generic version of Avanafil, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. PDE5 inhibitors work by blocking the PDE5 enzyme, which is responsible for breaking down cGMP (cyclic guanosine monophosphate). cGMP helps relax the blood vessels in the penis, leading to improved blood flow and an erection when sexually aroused. https://www.genericday.com/avana-50-mg.html
