| sodium aurothiomalate | <chemical> A variable mixture of the mono- and disodium salts of gold thiomalic acid used mainly for its anti-inflammatory action in the treatment of rheumatoid arthritis. It is most effective in active progressive rheumatoid arthritis and of little or no value in the presence of extensive deformities or in the treatment of other forms of arthritis. Pharmacological action: antirheumatic agents, gold. Chemical name: Butanedioic acid, mercapto-, monogold(1+) sodium salt (12 Dec 1998) |
| sodium aurothiosulfate | <chemical> An antirheumatic agent with the same actions and uses as gold sodium thiomalate. Pharmacological action: antirheumatic agents, gold. Chemical name: Aurate(3-), bis(monothiosulfato(2-)-O,S)-, trisodium, (T-4)- (12 Dec 1998) |
| sodium azide | <chemical> A cytochrome oxidase inhibitor which is a nitridizing agent and an inhibitor of terminal oxidation. Pharmacological action: enzyme inhibitors, indicators and reagents, mutagens, vasodilator agents. (12 Dec 1998) |
| sodium benzoate | C6H5COONa;used in chronic and acute rheumatism and as a liver function test. (05 Mar 2000) |
| sodium bicarbonate | <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) |
