Sodium salts can be categorized into:
|Sodium salts of some fatty acids|
In pharmaceutical technology acidic pharmaceutical substances are often converted into sodium salts, because they are more stable, more soluble or membrane-permeable than the drug itself. Example of such sodium salts are (selection): Bispyribac, bithionol, bosentan, brequinar, bromfenac, Cefmenoxime, ceftiofur, citicoline, diclofenac , Floxacillin, fosinopril, naproxen, Netobimin, ozagrel, pantoprazole, pemetrexed, sitamaquin, sitaxentan, sulfamiderazin, sulfapyridine, sulfaquinoxaline, sulfathiazole, sulfazecin, thiamylal and mesna. The disodium salt of cromolyn is also used as drug. Most of these salts are sodium salts of organic carboxylic acids or sulfonic acids.
Sodium salts of long chain sulfonic acids (e.g. sodium lauryl sulfate) are often included in toothpaste and shampoo. The sodium salts of fatty acids may serve as soaps and can therefore be called sodium soaps.
Examples of important inorganic sodium salts are sodium fluoride, sodium chloride, sodium bromide, sodium iodide, sodium sulfate, sodium bicarbonate and sodium carbonate. Sodium amide (NaNH2) is the sodium salt of ammonia (NH3).
