Vilitra is a prescription medication used to treat erectile dysfunction (ED). The active ingredient in Vilitra, Vardenafil, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for regulating blood flow in the penis. By blocking the action of this enzyme, Vilitra allows for the smooth muscles in the penile blood vessels to relax, leading to increased blood flow and the ability to achieve an erection in response to sexual stimulation.
