Romazicon( flumazenil ) data sheet


Romazicon, also known as Flumazenil, Anexate, Lanexat and Mazicon is the only benzodiazepine antagonist available on the market today. First approved by the FDA, it comes in injectable form only and has been found to be beneficial for people who get overly drowsy using other benzodiazepines. It has also been given successfully as an antidote for benzodiazepine overdoses.

Romazicon is fast acting and works by reversing or inhibiting the sedatory, psychomotor and recall impairment as well as respiratory depression effects of benzodiazepines. This is accomplished by antagonizing the effects of benzodiazepines on the central nervous system. More specifically the activity of the benzodiazepines at the recognition site on the GABA/benzodiazepine receptor complex is completely inhibited. Romazicon does not reverse the effects of opioids or inhibit the central nervous system effects of barbiturates, ethanol or general anesthetics.

  • Changes in vision including blurry vision.
