Eszopiclone Versus Zopiclone In The Treatment Of Insomnia

Eszopiclone 2mg is a barbiturate used to treat insomnia by increasing sleep latency as well as sleep maintenance.

Nonbenzodiazepine hypnotic eszopiclone, sold as Lunesta by Sepracor, is used to treat insomnia. It is the zopiclone active stereoisomer, which belongs to the cyclopyrrolones medication class. Cyclopyrrolone medicines have excellent effectiveness while being low in toxicity, making them a safer option for treating insomnia than other available options.

The FDA has authorized eszopiclone for the long-term treatment of insomnia, which is a big advantage. Many other hypnotic sedatives are only licensed for short-term (6-8 week) insomnia alleviation, thus this one stands out. When the FDA first authorized Eszopiclone.

Which is better, Eszopiclone or Zopiclone?

Eszopiclone 2mg, a zopiclone 10mg stereoisomer, is a cyclopyrrolone family non-benzodiazepine hypnotic drug. Eszopiclone, a synthetic molecule similar to zopiclone, has been demonstrated to be useful in the treatment of insomnia.

Because cyclopyrrolones have more selectivity, they are superior to benzodiazepines in that they maintain the hypnotic effect while having less anxiolytic and/or muscle-relaxing effects. As a result of these studies, eszopiclone has been shown to be beneficial in relieving insomnia and other comorbid conditions such as a high degree of sadness, generalized anxiety, osteoarthritis, and snoring.

Eszopiclone and zopiclone have not been studied side by side yet. Eszopiclone was shown to be more effective than racemic zopiclone in the post-hoc parametric analysis of reciprocally transformed data, but the results were mixed. The medications are available in the doses of Zopiclone 10mg, Zopiclone, Eszopiclone 2 mg, Eszopiclone 3mg, etc on safegeneric pharmacy.

The FDA approved eszopiclone in 2004 as a therapy for insomnia, but its clinical efficacy has also been established in long-term dosage trials (six to twelve months) and is not restricted to short-term usage.

Mode of action

Eszopiclone is a sedative that works quickly to put you to sleep and then keeps you asleep longer. It also helps keep you asleep longer by keeping you from waking up frequently during the night. The anticonvulsant and muscle hypnotic qualities of this medication have been demonstrated in animals, however, it is mostly utilized in humans for sedation.

  • Various consequences are associated with the central nervous system stimulant eszopiclone.
  • Changes in alertness, coordination, and the possibility of morning impairment increase with higher doses of eszopiclone.
  • Driving a car or engaging in other activities that need complete mental alertness the following morning should be avoided, according to safety precautions.
  • The usage of eszopiclone may lead to unusual sleep patterns. These patients should not be given eszopiclone anymore.
  • When using eszopiclone, stay away from alcoholic beverages and other CNS depressants.

Patients who have drank alcohol before or throughout the evening should not take the eszopiclone dosage. Eszopiclone should be used at the lowest effective dose feasible, especially to older patients who may be more sensitive to the drug’s side effects. Although eszopiclone has a lesser risk of dependency and abuse than other hypnotic medications, it has been misused and is reported to produce dependence.


Even though eszopiclone’s specific mechanism of action is still unknown, it’s expected to occur by interacting with GABA receptor subunits at binding sites near benzodiazepine receptors, which might explain its hallucinogenic and sedative effects now.

GABA-A (or GABAA) transmitter subunits 1, 3, and 5 are particularly favorable targets for this compound. Eszopiclone has a considerable effect on GABA-A channel currents. Activation of GABA-A receptors causes CNS depression through GABA-A channel activation. Eszopiclone is only eliminated in small amounts in the feces as the active ingredient.

Racemic zopiclone can be excreted in the urine in up to 75 percent of the oral intake as metabolites. Same excretion pattern for racemic zopiclone’s S-isomer, eszopiclone.
