Can you name the medicine to be kept under the tongue when a person suffers heart attack?

Nitroglycerin tablets are placed under your tongue in the event of chest pains due to angina, not for a heart attack. You can also use a nitroglycerin spray. The nitroglycerin acts to widen (dilate) the blood vessels in your heart allowing more blood to flow to your heart muscles. The pain is because not enough blood is available to your heart muscles.

The nitroglycerin tablets and spray are not explosive.
