Nitroglycerin is a medication used to treat and prevent chest pain (angina) caused by reduced blood flow to the heart. It works by dilating (widening) blood vessels, which increases blood flow and reduces the workload on the heart. Nitroglycerin is usually taken as a tablet that is placed under the tongue and absorbed through the lining of the mouth. It can also be administered in other forms, such as skin patches, sprays, or injections.
Nitroglycerin is commonly used in the management of angina and is also used in the treatment of certain types of heart attacks. It can provide rapid relief of chest pain, but its effects are usually short-lived, lasting only a few minutes. Nitroglycerin is not a cure for angina or heart disease, but it can help manage symptoms and improve quality of life.
Like all medications, nitroglycerin can cause side effects, including headache, dizziness, and flushing. It is important to follow the instructions of a healthcare provider when using nitroglycerin and to avoid using it without medical supervision. Nitroglycerin can interact with other medications, and it is important to inform a doctor of all medications being taken before starting nitroglycerin therapy.
