Nitrates are suspected to cause methemoglobinemia. [12] In otherwise healthy individuals, the protective enzyme systems normally present in red blood cells rapidly reduce the methemoglobin back to hemoglobin and hence maintain methemoglobin levels at less than one percent of the total hemoglobin concentration.
A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris. This group of drugs includes nitrates (esters of nitric acid), which are reduced to NO in the body, as well as some other substances.
The purpose of this mechanism to create NO is thought to be both sterilization of swallowed food (to prevent food poisoning) and to maintain gastric mucosal blood flow. [12] The nitrate-nitrite-nitric oxide pathway elevates nitric oxide through the sequential reduction of dietary nitrate derived from plant-based foods. [13]
Beets. Wong also suggests beets to lower blood pressure, explaining that they are rich in inorganic nitrate, which converts to nitric oxide. As a vasodilator, nitric oxide widens and relaxes blood ...

If you take nitrates like nitroglycerin, isosorbide dinitrate, or isosorbide mononitrate to treat hypertension (high blood pressure) or angina, you shouldn’t take Cialis.
Azotemia (from azot 'nitrogen' and -emia 'blood condition'), also spelled azotaemia, is a medical condition characterized by abnormally high levels of nitrogen-containing compounds (such as urea, creatinine, various body waste compounds, and other nitrogen-rich compounds) in the blood.
Greater than 70% metHb - High risk of death [5] This may be further compounded by the "functional hemoglobin's" decreased ability to release oxygen in the presence of methemoglobin. Anemia , congestive heart failure , chronic obstructive pulmonary disease , and essentially any pathology that impairs the ability to deliver oxygen may worsen the ...
