Vivanza is a medication used to treat erectile dysfunction. It contains the active ingredient vardenafil, which is a phosphodiesterase type 5 inhibitor, which works to dilate blood vessels by stimulating the secretion of nitric acid, which leads to increased blood flow to the penis, and enhanced sensitivity to sexual stimulation, which contributes to stimulating erection.
Vivanza is also used to treat pulmonary arterial hypertension.
