So yeah that’s right. Benzodiazepines (BZD) are ‘allosteric modulators’ they don’t actually bind the GABA receptor site on the BZD receptor. Instead, BZD’s increase the affinity of the neurotransmitter GABA to bind at the BZD receptor. In other words, if there was no GABA neurotransmitters BZD’s would have no effect.
Additionally, administration on BZD causes rapid withdrawal of BZD receptors from the cell surface, which is another reason that likely increases their safety.
