Isosorbide

Drug Details

Isosorbide is a medication commonly prescribed to prevent chest pain (angina) in individuals with coronary artery disease. It belongs to a class of drugs known as nitrates, which work by relaxing and widening blood vessels, thereby improving blood flow to the heart and reducing its workload. Isosorbide is available in two forms: isosorbide mononitrate and isosorbide dinitrate. These medications are typically taken orally in tablet form, with dosing schedules varying based on the specific formulation and individual patient needs. Common side effects may include headaches, dizziness, and lightheadedness, especially when starting the medication. It's important to take isosorbide exactly as prescribed and not to stop it abruptly without consulting a healthcare provider, as doing so may worsen angina symptoms.
