Sodium nitrate has also been investigated as a phase-change material for thermal energy recovery, owing to its relatively high melting enthalpy of 178 J/g. [14] [15] Examples of the applications of sodium nitrate used for thermal energy storage include solar thermal power technologies and direct steam generating parabolic troughs. [14]
The nitrates are used for the treatment and prevention of angina and acute myocardial infarction, while molsidomine acts too slowly to be useful for the treatment of acute angina. [2] For quick action in the treatment of angina, glyceryl trinitrate is used in form of a sublingual spray (nitro spray) or as soft capsules to be crunched.
Sodium nitrite is used as a medication together with sodium thiosulfate to treat cyanide poisoning. [26] It is recommended only in severe cases of cyanide poisoning and has largely been replaced by use of hydroxocobalamin , [ 27 ] a form of vitamin B12 , but given in much higher doses than needed nutritionally.

Sodium nitrite/sodium thiosulfate, sold under the brand name Nithiodote, is a fixed-dose combination medication used as an antidote for cyanide poisoning. [1] It contains sodium thiosulfate and sodium nitrite. [1] It is given by intravenous infusion into a vein. [1] It was approved for medical use in the United States in January 2011. [2]
Sodium thiosulfate is a classical antidote to cyanide poisoning, [10] For this purpose it is used after the medication sodium nitrite and typically only recommended for severe cases. [4] [6] It is given by injection into a vein. [4] In this use, sodium nitrite creates methemoglobinemia which removes cyanide from mitochondria. [6]
Sodium nitroprusside (SNP), sold under the brand name Nitropress among others, is a medication used to lower blood pressure. [3] This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding. [3] It is used by continuous injection into a vein. [3]
Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid .
Originally, it was simply a liquid lye (sodium hydroxide). In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite . Sodium hypochlorite is used in low (5%) concentration as laundry bleach and in higher concentrations as a swimming pool disinfectant.
