Vasodilation is the widening of blood vessels. The process is the opposite of vasoconstriction , which is the narrowing of blood vessels. When blood vessels dilate , the flow of blood is increased due to a decrease in vascular resistance and increase in cardiac output [ further explanation needed ]. Therefore, dilation of arterial blood vessels mainly the arterioles [ citation needed ] decreases blood pressure.

Common side effects include headache, muscle pain, flushed skin, and nausea. Tadalafil was approved for medical use in the United States in Tadalafil is used to treat erectile dysfunction ED , benign prostatic hyperplasia BPH , and pulmonary arterial hypertension. The pulmonary vascular lumen is decreased in PAH as a result of vasoconstriction and vascular remodeling, resulting in increased pulmonary artery pressure and pulmonary vascular resistance.
