Vilitra 20 Mg contains the active ingredient vardenafil, which belongs to a class of drugs known as PDE5 inhibitors. These medications work by increasing blood flow to the penis, allowing men with ED to achieve and maintain an erection when sexually stimulated. The science behind it involves relaxing the muscles of the blood vessels in the penis, enabling more blood to flow in. Vilitra 20 Mg blocks the action of an enzyme called phosphodiesterase type 5 (PDE5), which usually breaks down a substance called cGMP.
