Sublingual or buccal nitroglycerin should not be swallowed because the liver destroys most of the drug and makes it ineffective.The drug should be kept in place until it dissolved.Patients should not drink or eat until the tablet is dissolved.A tingling sensation as the tablet dissolves indicates that the drug is potent and any time a patient's chest pain persists after using one tablet,the prescriber should be notified.
