The primary ingredient in nitroglycerin is, as its name suggests, nitroglycerin. This compound is a volatile, explosive liquid that is also used medically as a vasodilator.
What is Nitroglycerin Used For?
Medically, nitroglycerin is used to treat chest pain, specifically angina pectoris, which is often associated with coronary artery disease. It works by relaxing and widening blood vessels, which improves blood flow to the heart muscle [1]. In its non-medical applications, nitroglycerin is a key component in explosives like dynamite.
How Does Nitroglycerin Work in the Body?
When administered, nitroglycerin is converted to nitric oxide (NO) in the body. Nitric oxide is a signaling molecule that causes the smooth muscle in the walls of blood vessels to relax. This relaxation leads to vasodilation, or the widening of blood vessels. The increased diameter allows more blood to flow, reducing the workload on the heart and relieving the symptoms of angina [2].
Are There Different Forms of Nitroglycerin?
Nitroglycerin is available in various formulations for medical use, including sublingual tablets, sprays, patches, and intravenous solutions [3]. The specific form and dosage depend on the patient's condition and the desired speed of action.
What Are the Risks of Using Nitroglycerin?
Because nitroglycerin is a vasodilator, common side effects include headaches, dizziness, and a drop in blood pressure [2]. It is also a potent explosive, and improper handling can lead to serious accidents.
What Other Ingredients Might Be in Nitroglycerin Products?
Medical formulations of nitroglycerin contain inactive ingredients, also known as excipients, which help stabilize the drug, control its release, or improve its taste and texture. The exact inactive ingredients vary depending on the specific product and its dosage form. For example, sublingual tablets might contain lactose, microcrystalline cellulose, and dicalcium phosphate, while transdermal patches involve adhesives and skin-penetrating agents [3].
