Alprazolam Pharmacology


About Alprazolam
Benzodiazepine derivative, Anti anxiety.
Mechanism of Action of Alprazolam
Alprazolam mainly acts on Limbic system and ascending reticular formation in the CNS and binds to the BZD receptor. The binding will facilitates GABA mediated chloride channel opening and produce hyperpolarisation. This will produce an increase in the concentration of the inhibitory neurotransmitter GABA and increase in chloride ions and decreases firing rate of neuron. This in turn alters normal functions of the body.
