How Xanax Affects Neurotransmitters
How Xanax Works
Alprazolam enhances GABA-A receptor activity by binding the benzodiazepine site, increasing chloride conductance and neuronal inhibition. This produces rapid anxiolytic, sedative, muscle relaxant, and anticonvulsant effects. Onset within 15–30 minutes.
