Trolnitrate

Trolnitrate (triethanolamine trinitrate, commonly used in the form of biphosphate salt also known as metamine) is an organic nitrate with vasodilator activity that is used to prevent or ameliorate attacks of angina pectoris. Trolnitrate dilates the coronary vessels because of its basic action as a smooth muscle depressant, just as do nitroglycerin and other organic nitrates.
