How Does Alprazolam Affect GABA Signaling?

Alprazolam binds to the benzodiazepine site on gamma-aminobutyric acid type A receptors in the brain. This increases GABA-mediated synaptic inhibition, which reduces activity in neural pathways involved in anxiety and panic symptoms. Its effects also account for sedation and impaired coordination that can occur during treatment.

When Is Alprazolam Prescribed?

Alprazolam tablets are approved for the acute treatment of generalized anxiety disorder in adults and for treatment of panic disorder with or without agoraphobia in adults. Treatment length and continued need are reassessed during therapy. The lowest dose that controls symptoms is preferred, especially when treatment extends beyond the initial period.

How Are Alprazolam Tablets Dosed?

For generalized anxiety disorder, the recommended starting dose is 0.25 mg to 0.5 mg three times daily, with a maximum recommended daily dose of 4 mg. For panic disorder, treatment starts at 0.5 mg three times daily. Dose reductions are gradual when treatment ends to reduce withdrawal reactions.

What Major Risks Come With Alprazolam?

Alprazolam carries a boxed warning for profound sedation, respiratory depression, coma, and death when combined with opioids. The warning also covers abuse, misuse, addiction, physical dependence, and withdrawal reactions. Abrupt stopping or rapid dose reduction can trigger seizures and other serious withdrawal effects. Alprazolam can also impair driving and other activities requiring alertness.
