Benzodiazepine reversal with flumazenil--a review of the literature.
Benzodiazepines such as Valium (diazepam) or Versed (midazolam), as used in dental procedures for intravenous sedation, have been a boon to the profession. Yet in the event of sedation problems, no agent exists that consistently reverses all clinical effects of these drugs. This problem does not exist with narcotics, frequently employed in tandem with benzodiazepines, since an effective reversal agent, Narcan (naloxone hydrochloride), exists. It would be advantageous to effectively reverse benzodiazepines in cases of acute emergency with respiratory depression or paradoxical reactions, and to allow quick, full recovery after short dental procedures. None of the drugs currently available for benzodiazepine reversal, such as physostigmine, give consistent clinical results. The purpose of this paper is to discuss Flumazenil, a new specific benzodiazepine receptor antagonist, and its possible use for dental sedation procedures.
