Nitroglycerin was first used by the English physician, clinical pharmacologist, and toxicologist William Murrell to treat angina attacks in 1878, with the discovery of the interaction published that same year.

Nitroglycerin (glyceryl trinitrate) is available in tablets, ointment, solution for intravenous use, transdermal patches, or sprays administered sublingually. Some forms of nitroglycerin last much longer in the body than others. It has been shown that continuous exposure to nitrates can cause the body to stop responding normally to this medicine. Experts recommend that the patches be removed at night, allowing the body a few hours to restore its responsiveness to nitrates. Shorter-acting preparations can be used several times a day with less risk of the body's getting used to this drug.
