Nitroglycerin has long been administered to human patients suffering from chronic chest pain (angina). This medication works because it

is broken down into hormones that affect the heart

interferes with chemical cascades that trigger contraction of heart muscle

breaks down into nitric oxide, which increases blood flow to the heart

mimics the action of signal receptors
