User: I want to know more about the molecule with SMILES O=[N+]([O-])OC[C@H](O[N+](=O)[O-])[C@@H](CO[N+](=O)[O-])O[N+](=O)[O-].
Assistant: Sure, what is your question?
User: Please describe this drug.
Assistant: Erythrityl tetranitrate is erythritol in which each of the hydroxy groups has been converted to the corresponding nitrate ester. 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.
