seawater + sodium thiosulfate pentahydrate + sodium hyaluronate

This is a **combination product** containing seawater, sodium thiosulfate pentahydrate, and sodium hyaluronate. - **Seawater** is commonly used as an isotonic or hypertonic diluent in nasal or ophthalmic products to flush, hydrate, or cleanse mucosal surfaces but has no pharmacologically specific activity. - **Sodium thiosulfate pentahydrate** is an inorganic compound best known for its use as an antidote in cyanide poisoning, as well as treatment for calciphylaxis and to reduce cisplatin-induced ototoxicity, primarily through its sulfur-donating, detoxifying, anti-calcification, antioxidant, and anti-inflammatory effects. Its mechanism involves providing sulfur for detoxification and chelation[1][3][4]. - **Sodium hyaluronate** is the sodium salt of hyaluronic acid, widely used for lubrication, moisturizing, and as a wound-healing adjunct in ophthalmic, dermatologic, and joint products; it binds and retains water, forming a viscoelastic protective film. This specific combination may be formulated for topical, ophthalmic, or mucosal administration, aiming to combine osmoprotective, detoxifying, anti-inflammatory, and lubricating actions.
