Nitroglycerin

Nitro 2

Nitroglycerin (nitr) /-glis′ ​ ​ rin/, A potent smooth muscle relaxant and vasodilator used in transdermal patches and in a paste as well as in oral and sublingual tablets. It is prescribed for the prevention or relief of angina pectoris. There are recommended limits to the amount of nitroglycerin use before calling for emergency assistance (no more than 3 subligual tablets at 5-minute intervals). The drug should not be used continuously because tolerance develops within 24 to 48 hrs. Nitroglycerin is also used to treat pulmonary hypertension, to help treat CHF following acute MI, and to treat hypertensive emergencies during cardiovascular surgery.
