Zopiclone
Zopiclone is the racemic form of a nonbenzodiazepine, cyclopyrrolone with hypnotic and sedative activity and without significant anxiolytic activity. Although the exact mechanism of action remains to be fully elucidated, zopiclone is able to bind to and activate the omega-1 subtype of the alpha subunit of the gamma-aminobutyric acid-benzodiazepine GABA receptor complex (GABA-A), a chloride ionophore complex in the central nervous system (CNS). This leads to the opening of chloride channels, causing hyperpolarization, inhibition of neuronal firing, and enhancement of the inhibitory effect of GABA. This eventually leads to a hypnotic effect and allows for an induction of sleep.

4.1 Drug Indication

For the short-term treatment of insomnia.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Zopiclone is a nonbenzodiazepine hypnotic from the pyrazolopyrimidine class and is indicated for the short-term treatment of insomnia. While Zopiclone is a hypnotic agent with a chemical structure unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties, it interacts with the gamma-aminobutyric acid-benzodiazepine (GABABZ) receptor complex. Subunit modulation of the GABABZ receptor chloride channel macromolecular complex is hypothesized to be responsible for some of the pharmacological properties of benzodiazepines, which include sedative, anxiolytic, muscle relaxant, and anticonvulsive effects in animal models. Zopiclone binds selectively to the brain alpha subunit of the GABA A omega-1 receptor.

5.4 Absorption, Distribution and Excretion

Absorption

Rapidly absorbed following oral administration.


5.5 Metabolism/Metabolites

Extensively metabolized in the liver via decarboxylation (major pathway), demethylation, and side chain oxidation. Metabolites include an N-oxide derivative (weakly active; approximately 12% of a dose) and an N-desmethyl metabolite (inactive; approximately 16%). Approximately 50% of a dose is converted to other inactive metabolites via decarboxylation. Hepatic microsomal enzymes are apparently not involved in zopiclone clearance.


5.6 Biological Half-Life

Elimination half life is approximately 5 hours (range 3.8 to 6.5 hours) and is prolonged to 11.9 hours in patients with hepatic insufficiency.


5.7 Mechanism of Action

Zopiclone exerts its action by binding on the benzodiazepine receptor complex and modulation of the GABABZ receptor chloride channel macromolecular complex. Both zopiclone and benzodiazepines act indiscriminately at the benzodiazepine binding site on 1, 2, 3 and 5 GABAA containing receptors as full agonists causing an enhancement of the inhibitory actions of GABA to produce the therapeutic (hypnotic and anxiolytic) and adverse effects of zopiclone.
