nitroglycerin has been researched along with Mitral Incompetence in 45 studies
Nitroglycerin: A volatile vasodilator which relieves ANGINA PECTORIS by stimulating GUANYLATE CYCLASE and lowering cytosolic calcium. It is also sometimes used for TOCOLYSIS and explosives.
nitroglycerol : A nitrate ester that is glycerol in which nitro group(s) replace the hydrogen(s) attached to one or more of the hydroxy groups.
nitroglycerin : A nitroglycerol that is glycerol in which the hydrogen atoms of all three hydroxy groups are replaced by nitro groups. It acts as a prodrug, releasing nitric oxide to open blood vessels and so alleviate heart pain.
