NCIt definition : A short-acting benzodiazepine derivative that is structurally related to midazolam,
with sedative-hypnotic activity. Upon administration, remimazolam targets and binds
to a specific site on the gamma-aminobutyric acid (GABA)-A-chloride ionophore receptor
complex located on the neuronal membrane. Binding causes an allosteric modification
of the receptor thereby enhancing the affinity of GABA to the receptor leading to
an increase in the frequency of chloride-channel opening events, which leads to an
increase in chloride ion conductance, neuronal hyperpolarization, inhibition of the
action potential, and a decrease in neuronal excitability.;
