Trocer Spray(Nitroglycerin)

Therapeutic Group: Cardiovascular


Trocer Spray: Each metered dose spray contains Nitroglycerin USP 400 mcg


Nitroglycerin Spray act on smooth muscle of blood vessels. It dilates the peripheral veins, arteries, coronary vessels, thereby decreases cardiac pre and afterload, cardiac work oxygen demand. It also reduces venous return, lowers end-diastolic pressure in the right and left ventricles and improves myocardial function. Nitroglycerin Spray increases the tolerance of anginal patients to exercise. Nitroglycerin applied on the buccal mucosa is absorbed quickly; its effect becomes apparent within 1 minute.


Nitroglycerin spray is indicated for acute relief of an attack or prophylaxis of angina pectoris due to acute left ventricular failure or coronary artery disease.
