Sodium salts are salts composed of a sodium cation and any anion. The anion may be the conjugate base of some inorganic or organic acids, or any monatomic or polyatomic anion. They can be formed by the neutralization of acids with sodium hydroxide. Sodium salts can be categorized into: In pharmaceutical technology acidic pharmaceutical substances are often converted into sodium salts, because they are more stable, more soluble or membrane-permeable (bioavailable) than the base compound. Examples of such sodium salts are (selection): Bispyribac, bithionol, bosentan, brequinar, bromfenac, Cefmenoxime, ceftiofur, citicoline, cromolyn, diclofenac, Flucloxacillin, fosinopril, Mordant brown 33, naproxen, Netobimin, ozagrel, pantoprazole, pemetrexed, secobarbital, sitamaquin, sitaxentan, sulfamiderazin, sulfapyridine, sulfaquinoxaline, sulfathiazole, sulfazecin, thiamylal and mesna. Most of these salts are sodium salts of organic carboxylic acids or sulfonic acids. Herbicides are often used as sodium salts for the reasons discussed above. One example is the sodium salt of methylflupyrsulfuron. 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.
