Avana 100 mg is a prescription medicine used to treat erectile dysfunction (ED) in men. It contains avanafil, a phosphodiesterase type 5 (PDE5) inhibitor that helps increase blood flow to the penis during sexual stimulation, making it easier to achieve and maintain a firm erection. Avanafil works by blocking the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). When this enzyme is inhibited, cGMP levels rise, leading to relaxation of smooth muscles and widening of blood vessels in the penile tissue.
