Is Nitroglycerin A Blood Thinner
Just what to know what I asked, is it a blood thinner?
Thanks for your question.
Nitroglycerin (NTG) is not a blood thinner. NTG is a drug that quickly dilates blood vessels, especially the coronary arteries that provide blood and oxygen to the heart muscle itself.
When a person has a blockage in a coronary artery, and the heart demands more oxygen during exercise or strenuous activity, the heart cannot get the needed blood and patients experience discomfort in the chest. NTG dilates the coronary arteries which allows more blood flow through these vessels and in many cases improves the situation and reduces, or eliminates, the chest discomfort. In addition to the coronary arteries, other blood vessels in the body dilate, resulting in a lower blood pressure. This reduces the pressure that the heart has to pump against and therefore decreases the work of the heart which also helps the coronary artery situation by less oxygen demand.
Blood thinners help prevent clots from forming on these blockages which can result in a cardiac emergency.
I hope this has been helpful. Best wishes.
