Vasodilators in meniere's syndrome.

Vasodilators in pulmonary hypertension.

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...

Antianginal Agents and Vasodilators

“We now know that the coronary blood vessels in the atherosclerotic heart already are dilated and that ordinary doses of dilator drugs do not significantly increase blood supply to the heart; instead, anginal pain is relieved by a reduction of cardiac consumption of oxygen.” Although vasodilators are used in the treatment of angina, a more sophisticated understanding of the hemodynamic response...

Are inhaled vasodilators useful in acute lung injury and acute respiratory distress syndrome?

In patients with acute respiratory distress syndrome (ARDS), inhaled vasodilator can result in important physiologic benefits (eg, improved hypoxemia, lower pulmonary arterial pressure, and improved right-ventricular function and cardiac output) without systemic hemodynamic effects. Inhaled nitric oxide (INO) and aerosolized prostacyclins are currently the most frequently used inhaled vasodilat...
