XANAX  0.5MG TAB

Alprazolam 0.5mg tablets exert their therapeutic effects primarily through their interaction with the gamma-aminobutyric acid (GABA) receptors in the brain. This medication belongs to the benzodiazepine class of drugs, and it enhances the inhibitory effects of GABA, a neurotransmitter that reduces the excitability of neurons. By binding to specific sites on the GABA-A receptor complex, alprazolam increases the frequency of chloride channel opening, allowing more chloride ions to enter the neurons. This heightened chloride influx hyperpolarizes the neuron, making it less likely to fire, resulting in a calming effect on the central nervous system. This mechanism is responsible for the anxiolytic, sedative, and muscle relaxant properties of alprazolam, making it effective in the management of anxiety disorders and panic attacks.
