It is a vasodilator with properties similar to nitroglycerin. It is usually used diluted with lactose or other suitable inert excipients, in order to minimise the risk of explosion; undiluted erythrityl tetranitrate can be exploded by percussion or excessive heat. It has a role as a vasodilator agent and an explosive. It is functionally related to an erythritol."}]
