What is nitroglycerin?

Nitroglycerin is a drug commonly prescribed for people with heart conditions as it has been shown to relax the blood vessels, making it easier for the heart to pump and blood to circulate. Tablet, capsule or spray formulations are typical for heart patients. In recent years, the drug has been found to have benefit in the treatment of anal fissures when added to a topical ointment in reduced concentrations (0.2% or less).
