Nitroglycerin (Sublingual) Detailed Information

Nitroglycerin is a nitrate medication commonly used to prevent and relieve chest pain (angina) in patients with coronary artery disease. It works by relaxing and widening blood vessels, allowing more oxygen-rich blood to reach the heart, reducing strain and pain. This medication is essential for individuals suffering from heart-related conditions and is often prescribed as a fast-acting remedy.
It is available in various forms, including sublingual tablets, sprays, patches, and extended-release capsules. The sublingual tablet form is particularly effective for immediate relief of angina symptoms.
