Vardenafil is the action of PDE5 inhibitor. In simple terms, Vardenafil widens the blood vessels in the penis stopping the action of PDE5. All the sex starts in the brain with a sexual thought or physical stimulation. The signals are sent to the penis to create an erection. An erection is triggered by the release of nitric oxide that travels to the blood vessels and penile spongy spaces where a fixed-exchange reaction which creates another chemical called cyclic GMP. Cyclic GMP causes the blood vessel that allows open spaces within the penis spongy engorge with blood, which leads to erection. After sex, the body breaks down cyclic GMP using the enzyme PDE5 (phosphodiesterase type 5) to remove erection. Vardenafil works against allowing PDE5 cyclic GMP in the penis remains that creates a stronger erection.
