Xanax is a medicine used for the treatment of anxiety and panic disorders. It belongs to the benzodiazepines class of medication. It has an active ingredient called Alprazolam which suppresses the activity of our nervous system and decreases nervous agitation to provide a calming effect. Xanax helps in falling asleep better by increasing the duration of sleep and reducing panic awakenings. It enhances the effect of a natural chemical in our body that is GABA(gamma-aminobutyric acid). This medicine is available in the form of pills and should be taken after a doctor’s prescription only. It can be addictive so using it for other purposes or without consulting a doctor can be hazardous for your health. Xanax works by increasing the amount of the neurotransmitter GABA in the brain to promote calmness and a relaxed feeling.
