The Nitro-Dur transdermal infusion system is a flat unit designed to provide continuous controlled release of nitroglycerin through intact skin. The pharmacological action of nitroglycerin is relaxation of vascular smooth muscle and consequent dilation of peripheral arteries and veins, especially the latter. It is indicated for the prevention of angina pectoris due to coronary artery disease.
