Mechanism of action

Eszopiclone is the active S-enantiomer of zopiclone and acts as a positive allosteric modulator of GABA-A receptors, particularly those containing alpha-1 subunits. By enhancing the effect of the inhibitory neurotransmitter GABA, it increases neuronal hyperpolarization and reduces neuronal excitability, leading to sedation and sleep initiation. It is selective for GABA-A receptors over other CNS targets, which contributes to its favorable safety profile compared to older benzodiazepines.
