Prescription benzodiazepine (Schedule IV controlled substance) approved for generalized anxiety disorder and panic disorder. One of the most commonly prescribed benzodiazepines with rapid onset of action.

The science

How it works, mechanistically.

Core mechanism

Binds to the benzodiazepine site on GABA-A receptors, enhancing the effect of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). This increases chloride ion conductance, hyperpolarizes neuronal membranes, and reduces neuronal excitability, producing anxiolytic, sedative, muscle relaxant, and anticonvulsant effects.2,8
