Isosorbide mononitrate, sold under many brand names, is a medication used for heart-related chest pain (angina), heart failure and esophageal spasms.^[2] It can be used both to treat and to prevent heart-related chest pain; however, it is generally less preferred than beta blockers or calcium channel blockers.^[2] It is taken by mouth.^[2]

Common side effects include headache, low blood pressure with standing, blurry vision, and skin flushing.^[2] Serious side effects may include low blood pressure especially if also exposed to PDE5 inhibitors such as sildenafil.^[2] Use is not recommended in pregnancy.^[3] It is believed to work by relaxing smooth muscle within blood vessels.^[2]

It was patented in 1971 and approved for medical use in 1981.^[4] It is available as a generic medication.^[3] In 2022, isosorbide was the 119th most commonly prescribed medication in the United States, with more than 5 million prescriptions.^[5]^[6]
