The heart drug called nitroglycerin was once described like this in the American Heart Association’s journal Circulation:

“Newer drugs quickly replace older remedies. This has not been the case with nitroglycerin, now in continuous medical use for more than a century.

“Although other applications for it have been found in cardiology, nitroglycerin is the mainstay for affording rapid, indeed almost immediate, pain relief for angina pectoris.

“At a time when the cost of pharmaceuticals is growing out of reach for many, nitroglycerin is still obtainable for pennies and remains one of the best buys in medicine.”
