How Long Does Xanax Stay In Your System?

What is Xanax, and how does it work?

Xanax is the brand name for Alprazolam and is used to treat anxiety and panic disorders. It is part of a class of drugs called benzodiazepine, which enhances the neurotransmitter Gamma-aminobutyric Acid’s effect, producing a calm feeling in the body. Xanax is also known as a short-acting tranquilizer based on the severity of the disorder, and there are multiple doses ranging from 0.25mg to 3mg.

It is a benzodiazepine that increases the effect of GABA or Gamma-aminobutyric Acid. GABA is known to function as an inhibitory neurotransmitter and is responsible for decreasing abnormal activity in the brain by inhibiting or blocking the initiation, sending, or receiving of chemical messages. 

GABA is a centrally acting neurotransmitter where low levels of GABA are known to indicate stress and anxiety. Xanax increases GABA levels, reduces overactivity in the brain while producing a relaxing feeling, and decreases the symptoms of anxiety and panic.
