| sodium cromoglycate | <chemical> A chromone complex that acts by inhibiting the release of chemical mediators from sensitised mast cells. It is used in the prophylactic treatment of both allergic and exercise-induced asthma, but does not affect an established asthmatic attack. Pharmacological action: anti-asthmatic agents. Chemical name: 4H-1-Benzopyran-2-carboxylic acid, 5,5'-((2-hydroxy-1,3-propanediyl)bis(oxy))bis(4-oxo-, disodium salt (12 Dec 1998) |
| sodium cyanide | <chemical> Sodium cyanide (na(cn)). A highly poisonous compound that is an inhibitor of many metabolic processes and is used as a test reagent for the function of chemoreceptors. It is also used in many industrial processes. Pharmacological action: enzyme inhibitors, indicators and reagents, poisons. Chemical name: Sodium cyanide (Na(CN)) (12 Dec 1998) |
| sodium dehydrocholate | A cholagogue; also used to determine circulation time. (05 Mar 2000) |
| sodium diatrizoate | A water-soluble organic iodine compound formerly used for intravenous excretory urography and angiography. (05 Mar 2000) |
| sodium, dietary | Sodium or sodium compounds used in foods or as a food. The most frequently used compounds are sodium chloride or sodium glutamate. (12 Dec 1998) |
| sodium dihydrogen phosphate | NaH2PO4-H2O;used to increase urinary acidity. Synonym: primary sodium phosphate, sodium acid phosphate, sodium dihydrogen phosphate. (05 Mar 2000) |

| sodium dodecyl sulfate | <chemical> An anionic surfactant, usually a mixture of sodium alkyl sulfates, mainly the lauryl; lowers surface tension of aqueous solutions; used as fat emulsifier, wetting agent, detergent in cosmetics, pharmaceuticals and toothpastes; also as research tool in protein biochemistry. Pharmacological action: surface-active agent. Chemical name: Sulfuric acid monododecyl ester sodium salt (12 Dec 1998) |
| sodium dodecyl sulphate | See: SDS. (18 Nov 1997) |
| sodium erythorbate | <chemical> This compound is used in the food industry to keep processed meat, such as hot dogs and beef sticks, from turning strange colours. It is chemically similar to vitamin C, which was used for the same purpose before this compound, but only gives the body 1/20th of the vitamin C one would get from taking regular vitamin C. It is made from sugar, commonly beet and cane sugar. (09 Oct 1997) |
