Eszopiclone, marketed by Sepracor under the brand-name Lunesta, is a nonbenzodiazepine hypnotic agent (viz., a sedative) used as a treatment for insomnia. Eszopiclone is the active stereoisomer of zopiclone, and belongs to the class of drugs known as cyclopyrrones. Its main selling point is that it is approved by the U.S. Food and Drug Administration for long-term use, unlike almost all other hypnotic sedatives, which are approved only for the relief of short-term (6-8 weeks) insomnia.

Dược Lực Học : Eszopiclone is a nonbenzodiazepine hypnotic, pyrrolopyrazine derivative of the cyclopyrrolone class and is indicated for the short-term treatment of insomnia. While Eszopiclone 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. Eszopiclone binds selectively to the brain alpha subunit of the GABA A omega-1 receptor.
Cơ Chế Tác Dụng : Eszopiclone, marketed by Sepracor under the brand-name Lunesta, is a nonbenzodiazepine hypnotic agent (viz., a sedative) used as a treatment for insomnia. Eszopiclone is the active stereoisomer of zopiclone, and belongs to the class of drugs known as cyclopyrrones. Its main selling point is that it is approved by the U.S. Food and Drug Administration for long-term use, unlike almost all other hypnotic sedatives, which are approved only for the relief of short-term (6-8 weeks) insomnia. The mechanism of action of Eszopiclone is not completely understood. It is thought that Eszopiclone acts on the benzodiazepine receptors as an agonist and interacts with GABA-receptor complexes.
Dược Động Học :
▧ Absorption :
Rapidly absorbed following oral administration
▧ Protein binding :
52-59%
▧ Metabolism :
Following oral administration, eszopiclone is extensively metabolized by oxidation and demethylation.
▧ Route of Elimination :
Up to 75% of an oral dose of racemic zopiclone is excreted in the urine, primarily as metabolites.
▧ Half Life :
6 hours
Độc Tính : Side effects include viral infection, dry mouth, dizziness, hallucinations, infection, rash, and unpleasant taste, with this relationship clearest for unpleasant taste depending on doses.
Chỉ Định : For the treatment of insomnia
Tương Tác Thuốc :
  • Telithromycin Telithromycin may reduce clearance of Eszopiclone. Consider alternate therapy or monitor for changes in the therapeutic/adverse effects of Eszopiclone if Telithromycin is initiated, discontinued or dose changed.
  • Triprolidine The CNS depressants, Triprolidine and Eszopiclone, may increase adverse/toxic effects due to additivity. Monitor for increased CNS depressant effects during concomitant therapy.
  • Voriconazole Voriconazole, a strong CYP3A4 inhibitor, may increase the serum concentration of eszopiclone by decreasing its metabolism. Monitor for changes in the therapeutic and adverse effects of eszopiclone if voriconazole is initiated, discontinued or dose changed.
