lanosterol
| sodium nitrite | <chemical> Nitrous acid sodium salt. Used in many industrial processes, in meat curing, colouring, and preserving, and as a reagent in analytical chemistry. It is used therapeutically as an antidote in cyanide poisoning. The compound is toxic and mutagenic and will react in vivo with secondary or tertiary amines thereby producing highly carcinogenic nitrosamines. Pharmacological action: antidotes, food preservatives, indicators and reagents, mutagens. Chemical name: Nitrous acid, sodium salt (12 Dec 1998) |

| sodium nitroferricyanide | (Na2FeCCN)5NO-5H2O;a rapidly acting and potent arterial and venous vasodilator used in hypertensive emergencies and administered intravenously. Acts in a manner similar to vasodilator nitrates and nitrites by donating nitric oxide which produces vasodilation; also used as a reagent for detection of organic compounds in the urine. Synonym: sodium nitroferricyanide. (05 Mar 2000) |
| sodium nitroprusside | (Na2FeCCN)5NO-5H2O;a rapidly acting and potent arterial and venous vasodilator used in hypertensive emergencies and administered intravenously. Acts in a manner similar to vasodilator nitrates and nitrites by donating nitric oxide which produces vasodilation; also used as a reagent for detection of organic compounds in the urine. Synonym: sodium nitroferricyanide. (05 Mar 2000) |

| sodium orthophosphate | Na2HPO4-H2O;a laxative. Synonym: dibasic sodium phosphate, sodium orthophosphate. Sodium phosphate P 32, anionic radioactive phosphorus in the form of a solution of sodium acid phosphate and sodium basic phosphate; a beta emitter with a half-life of 14.3 days; after administration, highest concentrations are found in rapidly proliferating tissues; it is used in the treatment of polycythemia vera, chronic myelogenous leukaemia, and osseous metastases. See: chromic phosphate P 32 colloidal suspension. (05 Mar 2000) |
| sodium oxybate | <chemical> Sodium 4-hydroxybutyrate. Anaesthetic used for both induction and maintenance. It may cause bradycardia and dyskinesias. Sodium oxybate has been supplied illicitly as a drug of abuse promoted for body building, and weight loss. Pharmacological action: anaesthesia adjuvants, anaesthetics, intravenous. Chemical name: Butanoic acid, 4-hydroxy-, monosodium salt (12 Dec 1998) |
