Sodium thiosulfate pentahydrateProduct ingredient for Thiosulfuric acid
- Name
- Sodium thiosulfate pentahydrate
- Drug Entry
- Thiosulfuric acid
Thiosulfuric acid is available in its salt forms sodium thiosulfate and sodium thiosulfate pentahydrate. Sodium thiosulfate is part of the World Health Organization’s list of essential medicines, and it has a variety of industrial uses, including food preservative, water de-chlorinator and paper pulp bleaching agent.1 Sodium thiosulfate is rapidly degraded in the stomach; therefore, it is normally administered through other routes, such as intravenous or topical.1 Sodium thiosulfate is approved for the treatment of acute cyanide poisoning5,6,2 and it is frequently used in conjunction with sodium nitrite (a salt form of nitrous acid). Sodium thiosulfate is also used to reduce the risk of ototoxicity associated with cisplatin.7 When administered 6 hours after cisplatin chemotherapy, Sodium thiosulfate leads to a lower incidence of cisplatin-induced hearing loss among children without affecting its effectiveness.3,4
