Nitroglycerine relieves angina by generating nitric oxide, which dilates coronary arteries, improving blood flow to the heart.
Nitroglycerine, commonly used to relieve angina pain, works by generating nitric oxide (NO), which causes the dilation of coronary arteries and arterioles. NO is a vasodilator that helps relax smooth muscle, thus increasing blood flow to the heart. This mechanism helps alleviate angina symptoms by improving blood supply to the heart muscle.
