Mechanism of action

Alprazolam is a benzodiazepine that potentiates the effect of the inhibitory neurotransmitter GABA by binding to GABA-A receptors, increasing chloride ion influx and hyperpolarizing neurons. The Staccato delivery system uses a proprietary pulmonary inhalation technology to achieve rapid systemic absorption through the lungs, enabling faster onset of action compared to oral formulations. This rapid onset is intended to provide faster symptom relief in acute anxiety or panic situations.
