P3470Suppression of endothelin-1 signaling by macitentan improves isosorbide-5-mononitrate (ISMN) and isosorbide dinitrate (ISDN) induced endothelial dysfunction, oxidative stress and vascular inflammation

Chronic therapy with isosorbide-5-mononitrate causes endothelial dysfunction, oxidative stress, and a marked increase in vascular endothelin-1 expression.

AIMS Isosorbide-5-mononitrate (ISMN) is one of the most frequently used compounds in the treatment of coronary artery disease predominantly in the USA. However, ISMN was reported to induce endothelial dysfunction, which was corrected by vitamin C pointing to a crucial role of reactive oxygen species (ROS) in causing this phenomenon. We sought to elucidate the mechanism how ISMN causes endotheli...

Simultaneous measurement of plasma isosorbide dinitrate, isosorbide-2-mononitrate, and isosorbide-5-mononitrate by gas-liquid chromatography.

Contribution of isosorbide-5-mononitrate, a major metabolite of isosorbide dinitrate (ISDN), to the hemodynamic effect of ISDN administered orally in conscious dogs.

This study was designed to determine the extent, to which isosorbide-5-mononitrate (5-ISMN) contributes to the hemodynamic effect of isosorbide dinitrate (ISDN) in conscious dogs. Test drugs (ISDN or 5-ISMN) were given orally. Either ISDN or 5-ISMN produced a decrease in blood pressure dose-dependently, the decrease in pulse pressure being specific; the pattern of blood pressure change induced ...

Pentaerythrityl tetranitrate and nitroglycerin, but not isosorbide mononitrate, prevent endothelial dysfunction induced by ischemia and reperfusion.

BACKGROUND Short term exposure to nitroglycerin (GTN) has protective properties that are similar to ischemic preconditioning. Whether other organic nitrates such as pentaerithrityl tetranitrate (PETN) and isosorbide mononitrate (ISMN) have similar protective effects has not been explored. METHODS AND RESULTS In a randomized, parallel, double blind, controlled trial, 37 healthy young volunteer...
