Midazolam binds to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron at several sites w/in the CNS, including the limbic system, reticular formation. Enhancement of the inhibitory effect of GABA on neuronal excitability results by increased neuronal membrane permeability to Cl ions, which results in hyperpolarisation (a less excitable state) and stabilisation. Benzodiazepine receptors and effects appear to be linked to the GABA-A receptors.
