Mechanism of action

Alprazolam is a benzodiazepine that binds to GABA-A receptors and potentiates the action of GABA, the primary inhibitory neurotransmitter in the brain. This increases chloride ion influx into neurons, hyperpolarizing the cell membrane and reducing the likelihood of neuronal firing. The result is decreased anxiety, muscle relaxation, and sedation.
