Like how much misinformation can one cram into a single paragraph?
Firstly, there is no such thing as Metrobamate. I think you mean Meprobamate. (perhaps I am ignorant and you are speaking of some new drug used to calm metrosexuals?)
In any event, it is NOT a benzodiazapine. It *is* a tranqulizer, but not a benzo. In any case, it's rarely used nowadays.
Secondly, it's Xanax, not Xanex. And it is not considered to have any anti-psychotic properties. It *is* considered to have anti-depressant qualities. That's because of the triple ring structure it has stuck to it, similar to the molecules of the classic tricyclic anti-depressants such as Amitriptyline or Nortriptyline.
Thirdly, you compare in one sentence three drugs of three entirely different categories, implying all are anti-psychotics, of which only one was: Xanax, which is a benzo, Elavil (aka: amitripyline, its generic name), which is a tricyclic (or as some now call the heterocyclic) anti-depressant, and Thorazine, which is a classic anti-pscychotic (aka: neuroleptic)
Might as well say something like aspirin is not as strong as penicillin. You can't make such comparisons because they do entirely different things.
There is SOME validity to comparing Elavil and Xanax since Xanax has some anti-depressant effect. But still, it's main action is that of a benzdiazapine type tranquilizer.
You did at least get right what Xanax is usually prescribed for.
Withdrawals from any benzodiazepine can be very bad, this includes Valium, Klonopin, Metrobamate, Xanex and Ambien to name a few. Xanex is the only one of that drug group that gives you a feeling of euphoria so it is really more of an antipsychotic than a sleep aid but not as strong as Thorazine or Elavil. It is prescribed to people who have chronic panic attacks, anxiety and PTS rather than someone who has trouble sleeping. I see nothing wrong with taking a small dose at night for the long term at night if it improves the quality for yor life.
