Nitrates are typically prescribed for the treatment of angina and symptoms associated with congestive heart failure. They also have been found to be useful in the treatment of high blood pressure, or hypertension. The Texas Heart Institute notes that nitrates are vasodilators, which refers to the widening of blood vessels to improve blood flow. Nitrates also relax the veins and ease the work flow of the heart. Nitrates are prescribed by a physician but also may be supplemented naturally through foods.
Isosorbides
Isosorbide mononitrate and dinitrate are available in oral pills to dilate the peripheral arteries and veins to reduce left ventricular end-diastolic pressure, according to the U.S. National Library of Medicine. These medications may interact with other vasodilators and should not be used with alcohol. Side effects may include dizziness, facial flushing and headaches.
Nitroglycerin
Nitroglycerin medications come in spray and tablet forms. These medications are primarily used in the treatment of chest pain or angina caused by heart disease. Nitroglycerin is effective in lowering blood pressure because it relaxes blood vessels. It might have serious side effects, however, such as blurred vision, fainting and difficulty breathing. These nitrates are used effectively as an adjunct for blood pressure treatment to lower systolic hypertension in people resistant to other medications, according to the American Heart Association.
Nitrates from Food
The Dietary Approaches to Stop Hypertension, or DASH, diet is based on high intake of vegetables and fruits to lower blood pressure. Nitrates are commonly found in vegetables and fruits, and following such a diet offers a natural way to obtain nitrates prior to exploring medication options. This eating plan may lower blood pressure in two weeks when followed accordingly, DASHdiet.org reports. An example of this diet would include five servings of fruits and five servings of vegetables a day in addition to eating whole grains and lean meats. Consult with your physician before starting any new diet and to explore all the possible options for using nitrates to treat hypertension.
