Vilitra (vardenafil) is a prescription medication designed to treat Performance issues. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by blocking the action of the enzyme PDE5, which normally breaks down cyclic guanosine monophosphate (cGMP). cGMP plays a key role in relaxing the smooth muscles in the penis, allowing for increased blood flow and an erection.
