Nitrates relieve angina due to their vasodilator effect, which allows the overworked heart to provide sufficient blood flow. A fast-acting nitrate such as glyceryl trinitrate may be administered sublingually to relieve an angina attack. The long-acting nitrates such as isosorbide dinitrate can be taken orally to prevent angina attacks.

Transdermal nitroglycerine which has a slow-acting release, is administered through an adhesive patch, and can provide a long relief from pain caused by angina. Nitrates are also sometimes given to help relieve symptoms of heart failure.

Examples of nitrates: isosorbide dinitrate, isosorbide mononitrate, glyceryl trinitrate.
