    Middle-aged teacher liu in recent months in depressive feeling discomfort, chest hospital diagnosis of coronary heart disease (CHD). The doctor let him carry nitroglycerin, in case of angina pectoris attack. Once in the class, liu suddenly felt chest tightness, and the area before the heart pain.

However, suck it need to pay attention to the position. Can lead to low blood pressure caused by the improper position dizzy, dizzy, even fainted. Recumbent medicated, increase the change of blood volume, increase myocardial oxygen consumption, heart burden, affect curative effect. When administering nitroglycerin, should take half decubitus position, namely the top and bottom are about 45 degree Angle, maintain 15 ~ 20 minutes. In addition, also desirable seat, but after medicated to sit for 15 ~ 20 minutes. First effect, because the liver bioavailability is only 8%, so the sublingual nitroglycerin used to suck it, not swallow. Adults with 0.25 ~ 0.5 mg, is administered under the tongue work about 2 ~ 3 minutes, 5 minutes to achieve maximum effect, 1 piece can be repeated every 5 minutes, until the pain relief.
