| 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) |
| sodium p-aminohippurate | Used intravenously in renal function tests, to determine the renal plasma flow and the tubular excretion. (05 Mar 2000) |
| sodium p-aminophenylarsonate | H2N-C6H4-AsO(OH)(ONa)-3H 2O; a compound that was one of the first modern pentavalent arsenicals. Synonym: sodium arsanilate. (05 Mar 2000) |
| sodium perborate | NaBO2H2O2-3H2O;used in the extemporaneous preparation of hydrogen peroxide; a 2% solution is equivalent in germicidal action to 0.4% of hydrogen peroxide. (05 Mar 2000) |
| sodium peroxide | Na2O2;used externally as a paste or soap in the treatment of comedones and acne. (05 Mar 2000) |
| sodium pertechnetate | Na 99mTcO4;a radiopharmaceutical used for brain, thyroid, and salivary gland scanning. (05 Mar 2000) |
| sodium pertechnetate tc 99m | <chemical> A gamma-emitting radionuclide imaging agent used for the diagnosis of diseases in many tissues, particularly in the gastrointestinal system, cardiovascular and cerebral circulation, brain, thyroid, and joints. Pharmacological action: radiopharmaceuticals. Chemical name: Technetate (99TcO41-), sodium, (T-4)- (12 Dec 1998) |
| sodium phenolsulfonate | Has been used in tonsillitis and as an intestinal antiseptic; has no antiseptic properties. Synonym: sodium sulfocarbolate. (05 Mar 2000) |
| sodium phosphate | 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 polyanhydromannuronic acid sulfate | An anticoagulant drug prepared from alginic acid and having an action similar to that of heparin. (05 Mar 2000) |
| sodium polystyrene sulfonate | A cationic exchange resin used in hyperpotassaemia. (05 Mar 2000) |
| sodium potassium ATPase | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
| sodium-potassium-exchanging atpase | <enzyme> An enzyme that catalyses the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane atpase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. Chemical name: ATP phosphohydrolase (sodium-potassium-transporting) Registry number: EC 3.6.1.37 (12 Dec 1998) |
| sodium-potassium pump | A membrane-bound transporter that maintains the high potassium and low sodium intracellular concentrations relative to the extracellular medium. This exchange is accomplished at the expense of cellular energy in the form of ATP. (05 Mar 2000) |
