DROPERIDOL Usage And Synthesis
  • Chemical PropertiesPale Yellow Solid
  • OriginatorDehydrobenzperidol,Janssen,W. Germany,1963
  • UsesA D1, D2 dopamine receptor antagonist; butyrophenone antipsychotic and anti-emetic.
  • UsesH2 antihistamine
  • UsesA D1DR and D2DR inhibitor.
  • DefinitionChEBI: An organofluorine compound that is haloperidol in which the hydroxy group has been eliminated with the introduction of a double bond in the piperidine ring, and the 4-chlorophenyl group has been replaced by a benzimidazol-2-on-1-yl group. It is used in the management of chemotherapy-induced nausea and vomiting, and in conjunction with an opioid analgesic such as fentanyl to maintain the patient in a calm state of neuroleptanalgesia with indifference to surroundings but still able to cooperate with the surgeo .
  • Manufacturing ProcessA mixture of 10 parts of γ-chloro-4-fluorobutyrophenone, 5.5 parts of 1- (1,2,3,6-tetrahydro-4-pyridyl)-2-benzimidazolinone, 4 parts of sodium carbonate, and 0.1 part of potassium iodide in 176 parts of 4-methyl-2- pentanone is stirred and refluxed for 64 hours. The cooled reaction mixture is filtered and the solvent is evaporated from the filtrate to leave an oily residue which is dissolved in toluene. The toluene solution is filtered and the solvent is evaporated. The resultant residue is recrystallized from a mixture of 32 parts of ethyl acetate and 32 parts of diisopropyl ether to give 1-[1-[(4-fluorobenzoyl)propyl]-1,2,3,6-tetrahydro-4-pyridyl]-2-benzimidazolinone hydrate melting at about 145°-146.5°C.

  • Therapeutic FunctionTranquilizer
  • General DescriptionDroperidol, 1-{1-[3-(p-fluorobenzoyl)propyl]-1,2, 3,6-tetrahydro-4-pyridyl}-2-benzimidazolinone(Inapsine), may be used alone as a preanestheticneuroleptic or as an antiemetic. Because of its very shortactingand highly sedating properties, its most frequent useis in combination (Innovar) with the narcotic agent fentanyl(Sublimaze) preanesthetically.
  • General DescriptionDroperidol, 1-1-[3-(p-fluorobenzoyl)propyl]-1,2,[3,6-tetrahydro-4-pyridyl]-2-benzimidazolinone(Inapsine). Centrally acting acetylcholinesteraseinhibitors may increase the risk of antipsychotic-relatedEPS. CNS depressants may produce additive sedativeeffects (benzodiazepines, barbiturates, antipsychotics,ethanol, opiates, and other sedative medications).Droperidol in combination with certain forms of inhalationanesthetics may produce peripheral vasodilatation and hypotension.Metoclopramide may increase the risk of EPSproduced by droperidol.
