Description
Nitroglycerin is 1,2,3-propanetriol trinitrate, an organic nitrate whose structural formula is: and whose molecular weight is 227.09. The organic nitrates are vasodilators, active on both arteries and veins. The NITRO-DUR ® (nitroglycerin) Transdermal Infusion System is a flat unit designed to provide continuous controlled release of nitroglycerin through intact skin. The rate of release of nitroglycerin is linearly dependent upon the area of the applied system; each cm 2 of applied system delivers approximately 0.02 mg of nitroglycerin per hour. Thus, the 5-,10-, 15-, 20-, 30-, and 40-cm2 systems deliver approximately 0.1, 0.2, 0.3, 0.4, 0.6, and 0.8 mg of nitroglycerin per hour, respectively. The remainder of the nitroglycerin in each system serves as a reservoir and is not delivered in normal use. After 12 hours, for example, each system has delivered approximately 6% of its original content of nitroglycerin. The NITRO-DUR transdermal system contains nitroglycerin in acrylic-based polymer adhesives with a resinous cross-linking agent to provide a continuous source of active ingredient. Each unit is sealed in a paper polyethylene-foil pouch. Cross section of the system. nitroglycerin chemical structure cross section of system
