Isosorbide Dinitrate: The Life-Saving Drug for Heart Disease
What is Isosorbide Dinitrate?
Isosorbide dinitrate is a nitrate medication used to treat angina (chest pain) and heart failure, myocardial infarction. It works by dilating blood vessels of heart and other organs, which helps reduce the workload on the heart, increase its oxygenation and improve blood flow.
How Isosorbide Dinitrate Works
It converts into nitric oxide, which relaxes and dilates blood vessels, thus reducing blood pressure and improving oxygen flow to the heart, helping to relieve chest pain and other symptoms of heart disease.
When to Use Isosorbide Dinitrate
