| gold sodium thiomalate | <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) |
|---|---|
| gold sodium thiosulfate | <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) |
| menadiol sodium diphosphate | Tetrasodium 2-methyl-1,4-naphthalenediol-bis(dihydrogen phosphate);a dihydro derivative of menadione, with similar vitamin K activity. (05 Mar 2000) |
| menadione sodium bisulfite | It possesses the same action and is used for the same purposes as menadione or vitamin K; it differs, however, from menadione in being water-soluble. (05 Mar 2000) |

| chloramphenicol sodium succinate | <chemical> Chloramphenicol-alpha-(sodium succinate);the water-soluble sodium succinate derivative of chloramphenicol, suitable for parenteral administration; antibacterial activity, uses, and side effects are similar to those of the parent compound. (05 Mar 2000) |
| cholistine sulphomethate sodium | Pentasodium colistinmethanesulfonate;contains the pentasodium salt of the penta(methanesulfonic acid) derivative of colistin A as the major component, with a small proportion of the pentasodium salt of the same derivative of colistin B; an effective antibiotic against most Gram-negative bacilli (except Proteus), given intramuscularly. See: colistin sulfate, polymyxin. Synonym: cholistine sulphomethate sodium, colistin sulfomethate sodium. (05 Mar 2000) |
| methicillin sodium | Sodium 2,6-dimethoxyphenylpenicillin monohydrate;a semisynthetic penicillin salt for parenteral administration; restriction of its use to infections caused by penicillin G-resistant staphylococci is recommended; it is less effective than penicillin G in infections caused by haemolytic streptococci, pneumococci, gonococci, and penicillin G-sensitive staphylococci. Synonym: sodium methicillin. (05 Mar 2000) |
