Short term treatment of anxiety Alprazolam Pharmacia & Upjohn
How does it work?
Alprazolam belongs to a group of medicines called benzodiazepines. It acts on
receptors in the brain (GABA receptors) causing the release of a chemical called
GABA (gamma amino butyric acid). GABA is a major inhibitory chemical in the
brain involved in inducing sleepiness and control of anxiety and fits.
Alprazolam acts by increasing the activity of GABA, thereby reducing the
functioning of certain areas of the brain. This results in sleepiness, a
decrease in anxiety and relaxation of muscles.
Alprazolam
is most commonly used to treat insomnia. It decreases the time taken to fall
asleep and nocturnal awakenings, as well as increasing the total amount of time
spent sleeping. As alprazolam remains active in the body for many hours,
drowsiness may occur the next day.
Alprazolam
is most commonly used to relieve anxiety in serious anxiety related conditions.
It is not recommended for the long-term treatment of anxiety due to the
development of dependence.
