• 使用

  Demecarium is a disymmetrical compound that contains two ammonium and two carbamate groups. It is a reversible cholinesterase inhibitor that is longer lasting than the others. It is used to constrict pupils, elevate intraocular pressure in treating glaucoma, and also for alleviating atropine mydriasis.

• 使用

  Demecarium Bromide is an acetylcholinesterase inhibitor and veterinary medicine used to treat elevated intraocular pressure associated with primary glaucoma.

• 定義

  ChEBI: The methobromide salt of the N,N'-bis[3-(dimethylamino)phenyl carbamate] derivative of 2,13-diazatetradecane. It is an inhibitor of acetylcholinesterase and pseudocholinesterase, with a long duration of action. It is u ed in the treatment of chronic open-angle glaucoma: in the eye, it causes constriction of the iris sphincter muscle and the ciliary muscle, facilitating the outflow of the aqueous humor and so reducing intraocular pressure.

• 一般的な説明

  Demecarium bromide,(m-hydroxyphenyl)trimethylammonium bromide, decamethylenebis[methylcarbamate] (Humorsol), is the diester of(m-hydroxyphenyl)trimethylammonium bromide with decamethylene-bis-(methylcarbamic acid) and thus is comparableto a bis-prostigmine molecule.
  It occurs as a slightly hygroscopic powder that is freelysoluble in water or alcohol. Ophthalmic solutions of the drughave a pH of 5 to 7.5. Aqueous solutions are stable and maybe sterilized by heat. Its efficacy and toxicity are comparableto those of other potent anticholinesterase inhibitor drugs. Itis a long-acting miotic used to treat wide-angle glaucomaand accommodative esotropia. Maximal effect occurs hoursafter administration, and the effect may persist for days.

• 合成

  Demecarium, N,N??-decamethylene-bis-[meta-(N-methylcarbamoyloxy)- phenyl-trimethylammonium] hydroxide (13.2.18), is made by reacting two moles of phosgene with 1,10-bis-(methylamino)-decano(N,N??-dimethyldecamethylen-1,10-diamine, giving the bis-carbamoylchloride (13.2.16), which is transformed into bis-carbamoylester (13.2.17) by reaction with two moles of the 3-dimethylaminophenol sodium salt. Reacting this with methylbromide gives demecarium (13.2.18) [49].
