flutazolam flutazolam flutazolam (coreminal, ms-4101) is a drug which is a benzodiazepine derivative. it was invented in japan, and this is the main country in which it has been used medically. it has sedative, muscle relaxant, anticonvulsant, and anxiolytic effects similar to those produced by other benzodiazepine derivatives, and though it is around the same potency as diazepam, it produces a more marked sedation and impaired coordination. it is indicated for the treatment of insomnia. its major active metabolite is n-desalkylflurazepam, also known as norflurazepam, which is also a principal metabolite of flurazepam (trade name dalmane). while flutazolam has a very short half-life of only 3.5 hours, n-desalkylflurazepam has a long half-life of between 47–100 hours. not to be confused with fluetizolam. flutazolamclinical datatrade namescoreminal (jp)other names13-chloro- 2-(2-fluorophenyl)- 9-(2-hydroxyethyl)- 3-oxa- 6,9-diazatricyclo tetradeca-1(10),11,13- trien- 8-oneahfs/drugs.cominternational drug namesroutes ofadministrationorallegal statuslegal status us: unscheduled in general: unscheduled, rx-only in japan pharmacokinetic datametabolismhepaticelimination half-life3.5 hours (parent compound); 47-100 hours (major metabolite)identifiers iupac name 10-chloro-11b-(2-fluorophenyl)-7-(2-hydroxyethyl)-3,5-dihydro-2h-oxazolobenzodiazepin-6-one cas number27060-91-9 npubchem cid3398chemspider3281 yunii5g2k7o5d8skeggd01286 ychemblchembl1697836 ncomptox dashboard (epa)dtxsid6023072 chemical and physical dataformulac19h18clfn2o3molar mass376.81 g·mol−13d model (jsmol)interactive image smiles fc1ccccc1c42occn2cc(=o)n(c3c4cc(cl)cc3)cco inchi inchi=1s/c19h18clfn2o3/c20-13-5-6-17-15(11-13)19(14-3-1-2-4-16(14)21)22(8-10-26-19)12-18(25)23(17)7-9-24/h1-6,11,24h,7-10,12h2 ykey:wmfsstnvxwnlki-uhfffaoysa-n y ny (what is this?)
