Anti-Angina drugs are medicines that
relieve the symptoms of Angina Pectoris (severe chest pain).
Purpose
The dull, tight chest pain of Angina occurs when the heart's muscular wall
is not getting enough oxygen. By relaxing the blood vessels, Anti-Angina
Drugs reduce the heart's work load and increase the amount of oxygen-rich
blood that reaches the heart. These drugs come in different forms, and are
used in three main ways:
- Taken regularly over a long period, they reduce the number of angina
attacks.
- Taken just before some activity that usually brings on an attack,
such as climbing stairs, they prevent attacks.
- Taken when an attack begins, they relieve the pain and pressure.
Description
Anti-Angina Drugs, also known as Nitrates, come in many different forms:
tablets and capsules that are swallowed; tablets that are held under the
tongue, inside the lip, or in the cheek until they dissolve; stick-on
patches; ointment; and in-the-mouth sprays. Commonly used Anti-Angina Drugs
include Isosorbide Dinitrate and Nitroglycerin. These medicines are
available only with a physician's prescription.
