Also known as 1,2,3-Propanetrioltrinitrate, 1,2,3-Propanetriyl nitrate, Glycerin trinitrate, Glycerol trinitrate, Glycerol, nitric acid triester, Glyceroli trinitratis, Glyceroltrinitrat, Glyceryl trinitrate, Minitran, NG, Natispray, Nitro-dur, Nitroglicerina, Nitroglycerine, Nitroglycerol, Nitrolingual, Nitromed, Nitromist, Nitrostat, Rectiv, Rectogesic, Transderm nitro, Trinitrine, Trinitroglycerin, Trinitroglycerol

An organic nitrate with vasodilator activity. Nitroglycerin is converted into nitric oxide (NO) in smooth muscle and activates guanylyl cyclase, thereby increasing cGMP concentration, and resulting in smooth muscle relaxation. Dilatation of the veins results in decreased venous return to the heart, thereby decreasing left ventricular volume (reduced preload) and decreasing myocardial oxygen requirements. Arteriolar relaxation reduces arteriolar resistance (reduced afterload), thereby decreasing myocardial oxygen demands. In addition, nitroglycerine causes coronary artery dilatation, thereby improving myocardial blood distribution.

Can I take Nitroglycerin while breastfeeding?

Topical use of nitroglycerin for anal fissures by nursing mothers appears to have no adverse effects on their breastfed infants. Topical use on the nipples has been used for alleviation of Raynaud phenomenon of the nipples, but only after cessation of breastfeeding.[1] It should not be used topically on the nipples during breastfeeding. Sublingual and intravenous nitroglycerin have not been studied during breastfeeding. Observe infants for flushing and discomfort after breastfeeding.
