ToggleWhat is Zopiclone?
Definition and Classification
Zopiclone, often recognized by the brand name Imovane, is a prescription medication used to treat insomnia. It belongs to a class of drugs known as non-benzodiazepine hypnotics or “Z-drugs.” Zopiclone works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits neuronal activity in the brain, leading to a sedative effect.
History and Development
Zopiclone was developed in the 1980s and received approval for medical use in several countries. It was designed as an alternative to benzodiazepines, which were commonly used for sleep disorders but had a higher potential for dependence and side effects. Zopiclone quickly gained popularity due to its effectiveness and relatively safer profile.
Comparison with Other Sleep Aids
When compared to other sleep aids like Ambien (Zolpidem) and traditional benzodiazepines, Zopiclone has distinct advantages. Unlike benzodiazepines, Zopiclone has a lower risk of dependency and is less likely to cause daytime drowsiness. Zolpidem, another Z-drug, is similar to Zopiclone but may differ in onset and duration of action. Understanding these differences can help patients and healthcare providers choose the most suitable treatment.
Different Forms of Zopiclone
Zopiclone is primarily available in tablet form, but variations in formulation can affect how the medication is absorbed and its duration of action. Here are the different forms of Zopiclone:
1. Standard Tablets
Standard tablets are the most commonly prescribed form of Zopiclone. They are available in various strengths, typically ranging from 3.75 mg to Zopiclone 7.5 mg. These tablets are taken orally and start to take effect within about 30 minutes to an hour after ingestion, providing relief from insomnia for several hours.
2. Extended-Release Tablets
Extended-release tablets of Zopiclone are designed to release the medication gradually over an extended period. This formulation helps maintain a steady level of the drug in the bloodstream throughout the night, promoting sustained sleep without the need for additional doses. Extended-release Zopiclone is beneficial for individuals who have trouble staying asleep or experience frequent awakenings.
3. Liquid Formulation
Some formulations of Zopiclone are available in liquid form. This format may be preferred for individuals who have difficulty swallowing tablets or who require more precise dosing adjustments. Liquid Zopiclone typically has a similar onset and duration of action as standard tablets but offers flexibility in administration.
4. Sublingual Tablets
Sublingual tablets of Zopiclone are designed to dissolve under the tongue, allowing for rapid absorption into the bloodstream. This method bypasses the digestive system, potentially leading to faster onset of action compared to standard oral tablets. Sublingual Zopiclone may be useful for individuals who need quick relief from acute insomnia symptoms.
5. Controlled-Release Formulations
Controlled-release formulations of Zopiclone are engineered to release the medication slowly over a predetermined period. This approach ensures a consistent level of the drug in the body, minimizing fluctuations that can affect sleep patterns. Controlled-release Zopiclone may be prescribed to individuals who require a more precise control over their sleep cycle.
Each form of Zopiclone offers unique benefits depending on individual sleep patterns and preferences. It is essential to consult with a healthcare provider to determine the most suitable formulation based on your specific needs and medical history. Understanding these different forms can help you and your doctor make informed decisions about managing insomnia effectively.
Uses and Benefits of Zopiclone
Primary Uses
Zopiclone is primarily used to treat short-term insomnia. It is effective in helping individuals fall asleep faster, stay asleep longer, and reduce the frequency of night awakenings. This medication is usually prescribed for short-term use, typically no longer than two to four weeks, to minimize the risk of dependence.
Benefits
The benefits of Zopiclone extend beyond merely improving sleep quality. By helping patients achieve restful sleep, Zopiclone can enhance overall well-being, mood, and cognitive function. Adequate sleep is crucial for physical health, mental clarity, and emotional stability. Many patients report significant improvements in their daily lives after starting Zopiclone treatment.
Patient Experiences
Patient experiences with Zopiclone vary, but many individuals have found relief from chronic insomnia through its use. For example, one patient, Jane, shared her story: “After struggling with insomnia for years, Zopiclone was a game-changer for me. I finally started sleeping through the night and felt more energized during the day.”

How Zopiclone Works?
Mechanism of Action
Zopiclone works by modulating the activity of GABA, the primary inhibitory neurotransmitter in the brain. GABA reduces neuronal excitability, leading to a calming effect on the brain. By enhancing GABA’s action, Zopiclone induces sedation and helps patients fall asleep.
Onset and Duration
Zopiclone typically takes effect within 30 minutes to an hour after ingestion, making it a fast-acting sleep aid. Its effects can last for 6-8 hours, which is sufficient to cover a full night’s sleep. This duration helps patients maintain continuous sleep without waking up prematurely.
Dosage Forms
Zopiclone is available in tablet form, with common dosages including 3.75 mg, 5 mg, and 7.5 mg. The appropriate dosage depends on the patient’s age, medical condition, and response to treatment. Healthcare providers usually start with the lowest effective dose to minimize side effects.
Risks and Side Effects
Common Side Effects
Like all medications, Zopiclone comes with potential side effects. Common side effects include:
- Drowsiness
- Dizziness
- Dry mouth
- Bitter or metallic taste in the mouth
These side effects are usually mild and may diminish as the body adjusts to the medication.
Serious Risks
While rare, some individuals may experience serious risks, such as:
- Allergic reactions (rash, itching, swelling)
- Severe dizziness
- Hallucinations
- Behavioral changes (agitation, aggression)
Long-term Use
Long-term use of Zopiclone can lead to dependence, tolerance, and withdrawal symptoms. Dependence occurs when the body becomes accustomed to the medication, requiring higher doses to achieve the same effect. Tolerance can develop within a few weeks, reducing the drug’s efficacy. Withdrawal symptoms, such as anxiety, rebound insomnia, and tremors, can occur if the medication is abruptly discontinued.
Who Should Not Take Zopiclone?
Contraindications
Certain individuals should avoid Zopiclone, including those with:
- Severe liver disease
- Sleep apnea
- Myasthenia gravis
- Severe respiratory insufficiency
These conditions can exacerbate the sedative effects of Zopiclone, leading to serious complications.
Interactions with Other Drugs
Zopiclone can interact with other medications and substances, including:
- Alcohol: Increases the sedative effects and risks of side effects.
- Other sedatives or hypnotics: Can enhance the sedative effects, leading to excessive drowsiness.
- Certain antidepressants, antipsychotics, and antihistamines: May increase the risk of side effects.
Special Populations
Special populations, such as the elderly, pregnant women, and children, require careful consideration. The elderly are more susceptible to side effects and may need lower doses. Zopiclone is not recommended during pregnancy or breastfeeding due to potential risks to the fetus or infant. Its use in children is generally not advised.
Zopiclone and Addiction
Addiction Potential
Zopiclone has a potential for addiction and dependence, especially when used for extended periods or at higher doses. Addiction can occur when the medication is used to cope with stress or anxiety rather than strictly for insomnia.
Signs of Dependence
Signs of Zopiclone dependence include:
- Craving the medication
- Using higher doses than prescribed
- Experiencing withdrawal symptoms when not taking the medication
Managing Addiction
Managing Zopiclone addiction involves a gradual tapering of the dose under medical supervision to minimize withdrawal symptoms. Behavioral therapies, such as cognitive-behavioral therapy (CBT), can help address the underlying issues contributing to addiction and promote healthy sleep habits.
