isosorbide dinitrate
for Angina
Isosorbide dinitrate is a medication taken to prevent chest pain (angina) from heart disease by relaxing blood vessels to improve oxygen delivery to the heart. It is not effective for treating an ongoing angina attack, for which a sublingual tablet should be used. Common side effects include headache and dizziness. Regular and extended-release tablets are used for prevention, not for immediate treatment of an angina attack.
