Mechanisms compared
Xanax: Alprazolam binds to the benzodiazepine site of the GABA-A receptor and allosterically enhances GABA-mediated chloride conductance, hyperpolarising central nervous system neurons. Mirtazapine: Mirtazapine antagonises presynaptic α2-adrenergic autoreceptors and heteroreceptors, increasing noradrenaline and serotonin release.
