Vardenafil and other PDE5 inhibitors help treat ED by allowing more blood to flow to your penis. To understand how these drugs work, it helps to understand the erection process.

nitric oxide . - Nitric oxide diffuses inside your blood vessels and stimulates the formation of another molecule called cGMP.
- cGMP relaxes the blood vessels in your penis and allows more blood to flow into its tissues.
Vardenafil inhibits the enzyme PDE5 that breaks down cGMP. Inhibiting this enzyme increases the amount of cGMP available in your blood vessels and allows more blood to flow to your penis.
Along with treating ED, some types of PDE5 inhibitors are also used to treat a condition called pulmonary hypertension.
