Death may occur when GABAergic substances are combined with other depressants such as opiates, benzodiazepines, barbiturates, gabapentinoids, thienodiazepines or alcohol.[1]

It is strongly discouraged to combine these substances, particularly in common to heavy doses.

Summary sheet: Eszopiclone

Template:SubstanceBox/Esopiclone

Eszopiclone (also known by the trade names Lunesta) is a non-benzodiazepine hypnotic substance of the cyclopyrrolone class that is primarily used in the treatment of insomnia. Eszopiclone is known to belong to a family of drugs colloquially known as "Z-drugs". Other Z-drugs include Zopiclone (Imovane) zaleplon (Sonata) and zolpidem (Ambien and AmbienCR).

Eszopiclone is thought to increase the normal neurotransmission of the neurotransmitter GABA in the central nervous system in a similar yet distinct way to the activity of benzodiazepines. As Eszopiclone displays heavy sedating effects, it is has been approved for and is commonly sold as a sleeping pill.[citation needed]

While "Z-drugs" were initially thought to have less misuse potential than benzodiazepines, this appraisal has shifted somewhat in the last few years as a number of cases of addiction and habituation have been observed. Eszopiclone, like all "Z-drugs", is recommended to be taken on a short-term basis -- usually a week or less.[2] Daily or continuous use of the drug is usually not advised.[3]

Dangerous interactions

Although many psychoactive substances are safe to use on their own, they can quickly become dangerous or even life-threatening when combined with other substances. The following lists some known dangerous combinations, but may not include all of them. A combination that appears to be safe in low doses can still increase the risk of injury or death. Independent research should always be conducted to ensure that a combination of two or more substances is safe to consume.

Legal status

Handcuffs-300px.png

This legality section is a stub.

As such, it may contain incomplete or wrong information. You can help by expanding it.

  • United States: On Dec 15, 2004, the United States released eszopiclone as a treatment for insomnia. It is currently a Schedule 4 controlled substance, because it has abuse potential, just as benzodiazepines do. Possession without a prescription can lead to drug charges.

    Chemistry

    Zopiclone is a hypnotic nonbenzodiazepine drug of the cyclopyrrolone class. Zopiclone and its closely related dextrorotatory S-stereoisomer eszopiclone (Lunesta) are the most popular and available cyclopyrrolone drugs. This class of drugs is named for having a pyrrolone core, a five-membered ring with a nitrogen constituent (pyrrole) and a ketone group (-one).

    Pharmacology

    Eszopiclone, although structurally different from benzodiazepines, shares an almost identical pharmacological profile to them. Its mechanism of action works by binding to the same site as benzodiazepines and acts as a full agonist, which in turn positively modulates benzodiazepine-sensitive GABAA receptors and enhances GABA binding at the GABAA receptors to produce eszopiclone's subjective effects.[citation needed] Since GABA functions as the brain's predominant inhibitory neurotransmitter, this activation of receptors results in the sedative and anxiolytic effects of Eszopiclone.[citation needed]

    Subjective effects

    In comparison to other substances of a similar nature such as benzodiazepines, eszopiclone is commonly reported to present significantly more amnesic and disinhibiting effects in a manner similar to alcohol.

    The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. These effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

    Experience reports

    There are currently no anecdotal reports which describe the effects of this compound within our experience index. Additional experience reports can be found here:

    Toxicity and harm potential

    By itself, eszopiclone likely has a low toxicity relative to dose. However, it is potentially lethal when mixed with depressants like benzodiazepines, alcohol or opioids. When combined with one or several of these drugs the already existing chance of a having a "black-out" is significantly increased, leaving the user with very little to no memory of the events that occurred whilst under the influence of eszopiclone alone or combined with most other CNS depressants. Users have reported taking eszopiclone in combination with alcohol in an attempt to treat hangovers with varying degrees of success. It is strongly recommended that one use harm reduction practices when using this substance.

    Tolerance and addiction potential

    Eszopiclone is extremely physically and psychologically addictive. This compound may have an even greater addictive potential than benzodiazepines. Tolerance will develop to the sedative-hypnotic effects within a couple of weeks of daily use. After cessation, the tolerance returns to baseline in 7 - 14 days. Withdrawal symptoms or rebound symptoms may occur after ceasing usage abruptly following a few weeks or longer of steady dosing, and may necessitate a gradual dose reduction. Eszopiclone presents cross-tolerance with all benzodiazepines, meaning that after its consumption benzodiazepines and most other GABAgenic depressants will have a reduced effect.<ref>Eszopiclone and triazolam in insomnia associated with generalized anxiety disorder. If Eszopiclone has been taken for more than a few weeks, then the medication should be gradually reduced or preferably crossed over to an equivalent dose of diazepam (Valium) which has a much longer half-life, making withdrawal easier. One should then gradually taper the dose over a period of several months to avoid extremely severe and unpleasant withdrawal symptoms which can last up to two years after withdrawal if the withdrawal is done too abruptly. http://www.benzo.org.uk/manual/
