Why do people take nitroglycerin?

Nitroglycerin is a vasodilator medication, primarily used to treat or prevent angina (chest pain) caused by coronary artery disease (CAD).

When a person experiences angina, the heart muscle doesn't get enough blood and oxygen. Nitroglycerin works by relaxing and widening the blood vessels, including the arteries that supply blood to the heart. This dilation allows more blood to flow to the heart and reduces the pain associated with angina.

Nitroglycerin can be administered in various forms:

- Sublingual tablets: These small tablets are placed under the tongue and dissolve quickly, allowing the medication to be absorbed directly into the bloodstream.

- Transdermal patches: These adhesive patches are applied to the skin, releasing nitroglycerin continuously for a specified duration, typically 12 or 24 hours.

- Oral sprays: Nitroglycerin can also be delivered as a spray that is administered under the tongue.

Nitroglycerin is generally well-tolerated, but some common side effects may occur, including headache, flushing, dizziness, and nausea. Rarely, it can cause more severe hypotension (low blood pressure) and syncope (fainting).

It is important to use nitroglycerin exactly as prescribed by a healthcare professional and follow their dosing and frequency recommendations. Nitroglycerin is typically taken before or during an angina attack, but regular long-acting nitrates may be prescribed for long-term prevention.

If someone is experiencing chest pain or discomfort, they should seek immediate medical attention, especially if the symptoms are new, persisting, or accompanied by other concerning signs such as shortness of breath, jaw pain, or pain radiating to the arms. Nitroglycerin is a helpful medication for angina, but it is essential to use it appropriately under medical supervision.
