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 thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na 2 S 2 O 3 ·(H 2 O) x. Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water. The compound is a reducing agent and a ligand, and these properties underpin its applications. [2]
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]
Thiosulfate (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur with the chemical formula S 2 O 2− 3.Thiosulfate also refers to the compounds containing this anion, which are the salts of thiosulfuric acid, such as sodium thiosulfate Na 2 S 2 O 3 and ammonium thiosulfate (NH 4) 2 S 2 O 3.
Sodium Thiosulfate (STS) is a calcium-chelating agent. It is typically used by patients who have excess calcium in their arteries due to kidney disease. In recent years, STS has also been used to treat patients with GACI.Proposed mechanism of STS action includes chelation or increased solubility of over mineralized calcium in arteries to be ...
A Risk Assessment Report (RAR) conducted by the European Union on sodium hypochlorite conducted under Regulation EEC 793/93 concluded that this substance is safe for the environment in all its current, normal uses. [26] This is due to its high reactivity and instability.

Exposure assessment: evaluation of exposure routes to a chemical in the environment; Risk characterisation: interpretation and combination of the previous steps to provide a practical estimate of the risk and any limitations and uncertainties. [7] NICNAS then produces risk management guidelines, which are regularly reviewed. These aim to balance:
