The mechanism of action of zopiclone.


The mechanism of action of the cyclopyrrolone hypnotic drug zopiclone involves allosteric modulation of the GABAA receptor. Zopiclone displaces the binding of [(3)H]-flunitrazepam with an affinity of 28 nM, and enhances the binding of the channel blocker [(35)S]-TBPS.
