MECHANISM OF ACTION Alprazolam is a long-acting benzodiazepine with anticonvulsant, anxiolytic, sedative, muscle relaxant and amnestic properties. It increases neuronal membrane permeability to chloride ions by binding to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron within the CNS and enhancing the GABA inhibitory effects resulting in hyperpolarisation and stabilisation.
