What is a bartiturate?

Barbiturates are drugs that act as central nervous system depressants, and by virtue of this they produce a wide spectrum of effects, from mild sedation to anesthesia. They are also effective as anxiolytics, hypnotics and as anticonvulsants. They have addiction potential, both physical and psychological. Barbiturates have now largely been replaced by benzodiazepines mainly due to benzodiazepines being significantly less dangerous in overdose. Barbiturates are derivatives of barbituric acid.

What is Xanax a stimmulant or depressant?

Its a depressant. Well, the individual that answered before pretty much hit the nail on the head. I will add some detail to the answer. Xanax is the trade name of alprazolam tablets, developed by Upjohn (Pfizer made the acquisition, so Pfizer produces the Trade name tablets). I will just use Xanax when referring to alprazolam. Xanax is a benzodiazepine, it is related to Valium, Ativan, and Klonopin. Xanax is used generally treat anxiety disorders and it is the most written prescription for benzodiazepines in the United States. It works well for reducing intense anxiety for example, panic attacks, anxiety attacks, and generalized anxiety disorder some cases. Benzodiazepines have largely replaced barbiturates, which were used prior to the advent of benzodiazepines. Benzodiazepine safety profile remains far superior barbiturates which is why they have largely replaced them. However, it is not stimulant of the central nervous system unless also paradoxical effects occur.

Tranquilizers and barbiturates fit into which drug category?

Valium, Xanax, and other depressants that work by reducing the function of the Central Nervous System. Kimber :) Actually, barbiturates and benzodiazepines are classes of drugs. So, the original question is problematic. (Also, just as a side note, the very definition of a depressant is that it inhibits/slows the working of the Central Nervous System.) Although, barbiturates and benzodiazepines produce similar effects and are often used for similar purposes, drugs fall into one category or the other. Valium, Xanax, Librium, etc., are all benzodiazepines whereas as Fiorocet is an example of a barbiturate.


Will ativan show as a barbiturate?

No. Ativan is a Benzodiazepine, not a Barbitiurate. That said, Benzodiazepines, like Barbiturates are Schedule IV drugs - meaning it can and probably will be screened for in drug tests.
