How Does Zopiclone Work?
This medication targets the GABA receptors in the Central Nervous System. Gamma-Aminobutyric Acid (GABA) is an inhibitory neurotransmitter that is responsible for calming down the brain and body. Zopiclone does not encourage the production of GABA in the central nervous system. Instead, it heightens the affinity for GABA by receptors, making the effects of this neurotransmitter stronger.
GABA is responsible for regulating mood and is crucial in sleep initiation. Some people take GABA supplements to help with sleeping problems and high blood pressure. Despite common use, there is no solid evidence that GABA supplements are truly effective.
