What is Xanax?

Xanax-Uses-Dosage-Side Effects-Warning. Buy Xanax Online Without Prescription.

Xanax is an antianxiety medication in the benzodiazepine family. This is the same family that includes diazepam (Valium), clonazepam (Klonopin), lorazepam (Ativan), flurazepam (Dalmane), and others.

Xanax works by decreasing abnormal excitement in the brain. The Food and Drug Administration (FDA) approved it in October 1981.

Benzodiazepines act on the brain and central nervous system (CNS) to produce a calming effect.

Xanax slows down the movement of brain chemicals that may have become unbalanced, resulting in a reduction in nervous tension and anxiety. Xanax works by boosting the effects of a natural chemical called gamma-aminobutyric acid, which is made in the brain.  Xanax-Uses-Dosage-Side Effects-Warning.  Buy Xanax Online Without Prescription
