Vilitra 20 is used to treat erection problems (erectile dysfunction) and benign prostatic hypertrophy (BPH). It is also sometimes used to treat pulmonary hypertension, which is high blood pressure in the arteries that feed the lungs.

One drug that falls within the category of phosphodiesterase (PDE) inhibitors is Vardenafil. By boosting blood flow to the targeted male region during stimulation, it treats erectile dysfunction. An erection is the outcome of the increased blood flow. Vardenafil facilitates easier blood flow by relaxing the arteries in the lungs.
