Erythrityl Tetranitrate is a vasodilator with general properties similar to nitroglycerin. Like many nitrate esters, ETN acts as a vasodilator, and was the active ingredient in the original "sustained release" tablets, made under a process patent in the early 50s. Ingesting ETN or prolonged skin contact can lead to absorption and what is known as a "nitro headache".
