| methotrexate | <drug> Analogue of dihydrofolate. Inhibits dihydrofolate reductase and kills rapidly growing cells. Therapeutic agent for leukaemias, but has a low therapeutic ratio. (18 Nov 1997) |
| methotrimeprazine | <drug> This drug has antipsychotic, tranquilising, antianxiety, sedative and pain-killing properties and it also increases the effectiveness of certain anesthetics. It is used to treat psychses in the elderly, schizophrenia, and manic depression. (09 Oct 1997) |
| methoxamine | <chemical> An alpha-adrenergic agonist that causes prolonged peripheral vasoconstriction. It has little if any direct effect on the central nervous system. Pharmacological action: adrenergic alpha-agonists, sympathomimetic, vasoconstrictor agents. Chemical name: Benzenemethanol, alpha-(1-aminoethyl)-2,5-dimethoxy- (12 Dec 1998) |
| methoxamine hydrochloride | Alpha-(1-Aminoethyl)-2,5-dimethoxybenzyl alcohol hydrochloride;; beta-hydroxy-beta-(2,5-dimethoxyphenyl)isopropylamine hydrochloride;a sympathomimetic amine. (05 Mar 2000) |
| methoxsalen | <chemical> A furocoumarin obtained from several different plants, especially psoralea corylifolia. It is used to increase skin pigmentation with sunlight in the treatment of depigmentation conditions such as vitiligo and may cause skin burns and liver damage. Pharmacological action: photosensitizing agents. Chemical name: 7H-Furo(3,2-g)(1)benzopyran-7-one, 9-methoxy- (12 Dec 1998) |
| methoxy- | Chemical prefix denoting substitution of a methoxyl group. (05 Mar 2000) |
| methoxychlor | <chemical> An insecticide. Methoxychlor has oestrogenic effects in mammals, among other effects. Pharmacological action: insecticide, organochlorine. Chemical name: Benzene, 1,1'-(2,2,2-trichloroethylidene)bis(4-methoxy- (12 Dec 1998) |
| methoxydimethyltryptamines | Compounds that contain the biogenic monoamine tryptamine and are substituted with one methoxy group and two methyl groups. Members of this group include several potent serotonergic hallucinogens found in several unrelated plants, skins of certain toads, and in mammalian brains. They are possibly involved in the aetiology of schizophrenia. (12 Dec 1998) |
| methoxyflurane | <chemical> An inhalation anaesthetic. Currently, methoxyflurane is rarely used for surgical, obstetric, or dental anaesthesia. If so employed, it should be administered with nitrous oxide to achieve a relatively light level of anaesthesia, and a neuromuscular blocking agent given concurrently to obtain the desired degree of muscular relaxation. Pharmacological action: anaesthetics, inhalation. Chemical name: Ethane, 2,2-dichloro-1,1-difluoro-1-methoxy- (12 Dec 1998) |
| methoxyflurane defluorinase | <enzyme> Metabolises methoxyflurane, isoflurane or enflurane enzyme induction with phenobarbital to inorganic fluorides. Registry number: EC 1.- (26 Jun 1999) |
| methoxyhydroxyphenylglycol | <chemical> 1-(4-hydroxy-3-methoxyphenyl)-1,2-ethanediol. Synthesised by animals from endogenous epinephrine and norepinephrine. It is found in brain, blood, csf, and urine, where its concentrations are used to measure catecholamine turnover. Chemical name: 1,2-Ethanediol, 1-(4-hydroxy-3-methoxyphenyl)- (12 Dec 1998) |
