Isosorbide Mononitrate ER

Drug Details

Isosorbide mononitrate is a medication designed to prevent chest pain, known as angina, which is associated with coronary artery disease. As part of the nitrate class of drugs, it functions by relaxing and dilating blood vessels, facilitating easier blood flow to the heart. This medication is not effective in stopping chest pain once it starts and should not be used immediately before physical activities such as exercise or sexual activity to prevent chest pain. It is available in two forms: the immediate-release version, which is taken twice daily with doses spaced 7 hours apart, and the extended-release version, which is taken once daily in the morning. While generally well-tolerated, some may experience headaches or dizziness. It's essential to consult with a healthcare professional for advice tailored to your condition and to discuss any other medications that might be necessary.
