Imdur known by its generic name Isosorbide Mononitrate is a prescription medication indicated to prevent chest pain (angina) in patients with a certain heart condition (coronary artery disease). It belongs to the group of medicines called nitrates. Isosorbide mononitrate works by relaxing the blood vessels and increasing the supply of oxygen and blood flow to the heart.
Isosorbide mononitrate is a medication used to treat angina; a chest pain caused by insufficient oxygen reaching the heart. It is also used to prevent heart attacks in people who have already had one. Imdur helps to prevent angina attacks, but it cannot be used to stop an angina attack that has already started.
Uses and Dosage
IMDUR comes in the form of an extended-release tablet that should be taken once daily as directed by your doctor. Swallow the whole or split tablet without crushing or chewing and use it with a half glass of water (4 ounces/120 milliliters) unless your doctor tells you otherwise. Only split the tablet if it has a score line and your doctor or pharmacist instructs you to do so.
The recommended starting dose of IMDUR tablets is usually 30 mg once daily, taken as a single 30 mg tablet or as half of a 60 mg tablet. Alternatively, your doctor may prescribe a starting dose of 60 mg taken as a single tablet once daily. Your doctor may adjust your dose based on your response to the medication and side effects. Follow your doctor's instructions on how to take IMDUR, including the dose and frequency of the medication.
