Managing Stress and Insomnia with Zopiclone Tablets: A Guide 2025

A word on Stress and Insomnia 

Sleep disruption is a common yet frequently overlooked problem that impacts health parameters and quality of life in a significant manner. An important aspect of sleep impairment is its association with stress levels, which results in the interconnection of the two phenomena. On one hand, researchers have attributed chronic sleep loss as a significant contributor to stress, while on the other hand, they have chalked out stress and anxiety as the leading cause of sleep problems. 

In either case, the fact remains that they coexist and impact the performance, memory levels and concentration of the individuals, increasing the risk of physical and mental health disorders. The need of the hour is an effective anxiolytic that can co-function as a sedative. While benzodiazepines can perform both roles, Z-drugs like Zopiclone are regarded as a safer option.

Zopiclone - Introduction 

Zopiclone belongs to the category of Z-drugs, A class of non-benzodiazepine drugs that work in the same manner as benzodiazepines ( a group of drugs working on the CNS to exert sedative and antidepressant properties ) but have a quicker onset and clearance. While used predominantly for insomnia conditions, what makes Zopiclone unique is its equal affinity to the different alpha units of the GABA receptors that enable its hypnotic, anxiolytic and muscle-relaxant properties.

Animal studies have shown Zopiclone to decrease the affinity for [3H]Flumazenil receptors, a property that indicates its selective modulation and enables it to offer a targeted sedative effect. Additionally, it reduces the risk of tolerance and dependency associated with traditional benzodiazepines while simultaneously enabling a lowered side-effect profile.

How does it work on Insomnia and Stress

While the exact mechanism of action of Zopiclone is still undergoing research, it has been observed that Zopiclone can bind to and activate the omega-1 subtype of the alpha subunit of Gamma-Aminobutyric acid, -Benzodiazepine receptor (GABA),  a neurotransmitter that plays an important role in sleep control. 

In the mammalian Central Nervous System, GABA receptors exist as GABA-A, GABA-B and GABA-C complexes, out of which GABA-A are hetero oligomeric chloride channels that, when activated, inhibit neurons in the arousal system and inhibit sleep latency

GABA-A receptors consist of :

Alpha - 1 Subtype in the cortex regulating cortex that regulates sleep.

Alpha - 3 Subtype in the reticular nucleus of the thalamus regulating sleep.

Omega -1 subtype that is associated with anxiolytic and hypnotic effects.

The binding of Zopiclone to the GABA-A receptors results in the opening of the chloride channels with subsequent hyperpolarization, inhibition of neuronal firing, and enhancement of the inhibitory effects of GABA, which enhance the hypnotic effects and induce sleep. 

In clinical trials, Zopiclone 7.5 mg improved sleep in chronic insomniacs with a similar efficacy of Nitrazepam 5mg, Flurazepam 15-30 mg, Triazolam 0,5 mg and Temazepam 20 mg while demonstrating satisfactory sedation in pre-surgery hospitalized patients.

A controlled, double-blind study conducted by a Joint Study Unit Group of the anaesthesiology departments in six national hospitals on the effectiveness of Zopiclone as a pre-operative hypnotic found Zopiclone 7.5 mg and 10 mg to be beneficial for a pre-operative night's sleep and have significantly fewer side-effects. The use of medication resulted in minimal impairment of psychomotor skills and mental acuity in the morning after its bedtime dose. Other than the development of bitter taste, patients had no complaints associated with its use. No serious side effects were reported as well, demonstrating Zopiclone's ability to be used as an alternative to other hypnotics for sedation especially in individuals demonstrating residual impacts.

Let's Talk about Zopiclone’s impact on stress

It has been postulated that Zopiclone is highly selective for alpha-5 subunits of the GABA receptors that play a crucial role in neuropsychiatric functions of the CNS; the alpha-5 subunits when activated by Zopiclone activate somatostatin interneurons and generate slow inhibitory postsynaptic currents in the hippocampal pyramidal cells.

The result is an impact on the sensory and motor cues and an overall influence over spatial, contextual and emotional information that comes in handy in the treatment of several neurological and psychiatric conditions like ageing, depression and schizophrenia and overall management of stress. To evaluate the effectiveness of Zopiclone on stress levels, researchers reviewed the impact of the medication on 45 difficult-to-treat psychiatric patients and found successful results on their levels of agitation and stress levels. Patients were treated for a minimum of three to a maximum of 498 days ( an average of 113.7 days ) with the number of Zopiclone administrations varying from twice daily to four times daily in an average 30 mg doses.

The results showed an improvement in illness severity in 69% of patients, out of which 60% showed improved or much-improved symptoms. 91% of patients demonstrated a clinically relevant reduction in aggressive symptoms. Use of Zopiclone for twelve weeks was well tolerated and none of the patients showed exacerbation of symptoms after that time period. The most common adverse reactions were sedation, drowsiness and tiredness

Zopiclone Residual Effect and Other Safety Factors

The results of four studies conducted at the Maastricht University have observed that the medication has clinically relevant performance-impairing impacts and for safety reasons, individuals should avoid driving or participating in skilled work in the morning after intake. In a drug monitoring study of 811 participating general practitioners, after evaluating the safety and tolerability of 2416 patients, researchers came to the conclusion that while being effective in managing insomnia, the subjective sleep duration was prolonged for two hours on average. Daytime well-being and vigilance were not impaired.

However, the medication impacted motor functions and was associated with falls in the elderly population and motor vehicle collisions.

Despite the safety and tolerability profile of Zopiclone, the medication is associated with residual effects and impaired motor performance that can pose a problem if you are driving after using the medication. The problem is especially evident as the medication is currently among the most prescribed hypnotic drugs and is more effective and safe than traditional hypnotics. 

The medication is also not recommended during pregnancy as it is associated with a higher chance of low birth weights and birth defects.

It is important to use it with Care

While establishing its effectiveness as a potent sedative and anxiolytic, Zopiclone use can result in adverse reactions in the form of rebound insomnia, increased heart rate and breathing difficulties if overused or used without guidance for long-term periods.

For safe usage, use it under the guidance of the physician, and if the adverse reactions or problems persist, get urgent medical help.
