Effects of inhaled versus intravenous vasodilators in experimental pulmonary hypertension.

Inhaled nitric oxide (NO) causes selective pulmonary vasodilation and improves gas exchange in acute lung failure. In experimental pulmonary hypertension, we compared the influence of the aerosolized vasodilatory prostaglandins (PG) PGI2 and PGE1 on vascular tone and gas exchange to that of infused prostanoids (PGI2, PGE1) and inhaled NO. An increase of pulmonary artery pressure (Ppa) from 8 to...

Pulmonary vasodilators.

Pulmonary vasodilators are an important treatment for pulmonary arterial hypertension. They reduce pulmonary artery pressure; improve hemodynamic function; alter ventilation/perfusion matching in the lungs; and improve functional quality of life, exercise tolerance, and survival in patients with severe pulmonary arterial hypertension. This paper reviews the currently available pulmonary vasodil...
