| prednisolone sodium phosphate | Prednisolone 21-(disodium phosphate);more soluble than prednisolone and the other prednisolone esters and useful when a rapid onset or a short duration of action is desired; suitable for intrasynovial, parenteral, and topical administration. Prednisolone succinate, prednisolone compound suitable for intramuscular, intravenous, or rectal administration. Prednisolone tebutate, same actions and uses as prednisolone but with longer duration of action and suitable for intrasynovial and soft tissue injection. Synonym: prednisolone butylacetate.

| sodium | <chemistry>, element> Sodium is a soft, silvery, highly reactive alkali metal which has an atomic number of 11 and an atomic weight of 22.990. It is most commonly found in the form of salt, sodium chloride (NaCl). It was first identified as an element by the English scientist Sir Humphrey Davy in 1807. Sodium chloride is a critical nutrient in humans (it plays an important role in nerve function), but too much of it can cause health problems such as aggravating high blood pressure. Pure metallic sodium is a fire hazard, and it can explode if it comes into contact with water. Other commonly used sodium compounds include soda ash (sodium carbonate, Na2CO3), baking soda (sodium bicarbonate, NaHCO3) and caustic soda (sodium hydroxide, NaOH). Abbreviation: Na (09 Oct 1997) |
| sodium-24 | The isotope of sodium with an atomic weight of 24, and a half-life of 14.96 hr; it emits beta and gamma rays, and is more easily prepared than the longer-lived, positron-emitting 22Na (half-life, 2.605 yr). It is used to measure extracellular fluid by indicator dilution. (05 Mar 2000) |
| sodium acetate | <chemical> The trihydrate sodium salt of acetic acid, which is used as a source of sodium ions in solutions for haemodialysis and peritoneal dialysis. It has also been used as a systemic and urinary alkaliser, diuretic, and expectorant. Pharmacological action: diuretics, expectorants, pharmaceutic aid. (12 Dec 1998) |
| sodium acid carbonate | <chemical> Carbonic acid monosodium salt (CHNaO3). A white, crystalline powder that is used as an electrolyte replenisher and systemic alkaliser. It is applied topically in solution to wash the nose, mouth, or vagina, and as a cleansing enema. Pharmacologic action: Acid neutralization. Uses: Preexisting metabolic acidosis, hyperkalemia, tricyclic or phenobarbital overdose. Dose in mEq: 0.3 * (base deficit) * (wt in kg). Potential complications: Metabolic alkalosis, hypercarbia, hyperosmolar state. Note: Since HCO3- does not cross cell membranes and CO2 does, the administration of bicarbonate may actually make tissues more acidotic. Chemical name: Carbonic acid monosodium salt. (12 Mar 2000) |
| sodium acid citrate | Na3C6H5O7 -2H2O; trisodium citrate;used as diuretic, antilithic, systemic and urinary alkaliser, expectorant, and anticoagulant (in vitro). Synonym: sodium acid citrate. (05 Mar 2000) |
| sodium acid phosphate | NaH2PO4-H2O;used to increase urinary acidity. Synonym: primary sodium phosphate, sodium acid phosphate, sodium dihydrogen phosphate. (05 Mar 2000) |
| sodium alginate | <plant biology> This gelatinous material, a polysaccharide extract from brown algae, is widely used in foods, medicines, and industrial and household products. The main algae that produce it are Laminaria species and Macrocystispyrifera (a chemically different version of algin is produced by the bacterium Azobacter vinelandii.) (09 Oct 1997) |
| sodium aminosalicylate | C6H3(p-NH2)(o-OH)-COONa-2H2O;used for the same purposes as aminosalicylic acid. (05 Mar 2000) |
| sodium ammonium ATPase | <enzyme> Aspect of atpase, EC 3.6.1.3 Registry number: EC 3.6.1.- Synonym: ammonium potassium atpase, na nh4 atpase, atpase, sodium ammonium (26 Jun 1999) |
| sodium antimonylgluconate | 1. Pentavalent sodium stibogluconate;Pentavalent sodium stibogluconate, used in the treatment of all types of leishmaniasis; toxic effects are frequent. Synonym: antimony sodium gluconate. 2. Trivalent sodium stibogluconate;Trivalent antimony sodium gluconate, used in the treatment of schistosomiasis; toxic effects are frequent. Synonym: sodium antimonylgluconate. (05 Mar 2000) |
