Severe hypotension, particularly in upright position, can occur even with low doses. The predominant venodilation results in decreased venous return to the heart by reducing the left ventricular end-diastolic volume, left ventricular end-diastolic pressure(preload), and the ventricular wall tension,therebyindirectly facilitating subendocardial blood flow. Some of the patient education strategies include educating regarding the following: Home care workers can help elderly patients prone to developing orthostatic hypotension with Home safety measures. Terms of Use and Privacy Policy: Legal. Do not chew or crush them.

Isosorbide mononitrate and dinitrate are both generally safe to take for a long time. Isosorbide mononitrate is in the class of drugs called nitrates that are used for treating and preventing angina.Other nitrates include nitroglycerin (Nitrostat, NitroQuick, Nitrolingual, Nitro-Dur and others) and isosorbide dinitrate (Isordil Titradose, Dilatrate-SR, Isochron).Nitrates are vasodilators (dilators of blood vessels). Isosorbide decreases the preload and worsens the right ventricular output causing severe hypotension. Changing positions slowly can help lessen dizziness. This is called glyceryl trinitrate, or GTN. Serious adverse reactions to the organic nitrates and nitrites are uncommon and their adverse effects mainly involve the CNS and cardiovascular system. Lincoln TM, Komalavilas P, Cornwell TL.
