AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Sodium thiosulfate is an inorganic salt administered by injection that protects against cisplatin-induced ototoxicity by both directly inactivating cisplatin and reducing intracellular oxidative stress through glutathione elevation. It is also indicated for calciphylaxis, a rare, life-threatening condition of vascular calcification. The drug works via dual mechanisms: chelation of platinum species and antioxidant activity within cells.
LOE Approaching
As a product nearing loss of exclusivity with moderate competitive pressure (30%), the brand team will shift focus toward defending market position and exploring indication expansion or combination strategies.
Mechanism of Action
Cisplatin-induced ototoxicity is caused by irreversible damage to hair cells in the cochlea hypothesized to be due to a combination of reactive oxygen species (ROS) production and direct alkylation of DNA leading to cell death. Sodium thiosulfate interacts directly with cisplatin to produce an…
