Product Description

Zopiclone 7.5mg

Zopiclone (brand name Imovane in Canada, Australia, Sweden, Finland, Norway, Russia and the United Kingdom, brand name Zimovane in Europe) is a nonbenzodiazepine hypnotic agent used in the treatment of insomnia. It is a cyclopyrrolone, which increases the normal transmission of the signal substance GABA in the central nervous system, as benzodiazepines do, but in a different way.

As zopiclone is sedating it is marketed as a sleeping pill. It works by causing a depression or tranquilization of the central nervous system. After prolonged use the body can become accustomed to the effects of zopiclone. When the dose is then reduced or the drug is stopped, withdrawal symptoms may result. These can include a range of symptoms similar to those of benzodiazepine withdrawal.

In the United States, zopiclone is not commercially available, although its active stereoisomer, eszopiclone, is sold under the name Lunesta (see History). Zopiclone is a controlled substance in the United States, Japan, Brazil, and some European countries, and may be illegal to possess without a prescription.

Zopiclone is known colloquially as a "Z-drug." Other Z-drugs include zaleplon (Sonata) and zolpidem (Ambien and AmbienCR) and were initially thought to be less addictive and/or habit forming than benzodiazepines. However, this appraisal has shifted somewhat in the last few years as cases of addiction and habituation have been presented. It is recommended that zopiclone be taken on a short-term basis, usually a week or less. Daily or continuous use of the drug is not usually advise

Zopiclone is indicated for the short term treatment of insomnia where sleep initiation or sleep maintenance are prominent symptoms. Long-term use is not recommended as tolerance, dependence and addiction can occur with prolonged use

Zopiclone, similar to other benzodiazepines and nonbenzodiazepine hypnotic drugs causes impairments in body balance and standing steadiness in individuals who wake up at night or the next morning. Falls and hip fractures are frequently reported. The combination with alcohol increases these impairments. Partial, but incomplete tolerance develops to these impairments.

An extensive review of the medical literature regarding the management of insomnia and the elderly found that there is considerable evidence of the effectiveness and lasting benefits of nondrug treatments for insomnia. Compared with the benzodiazepines, the nonbenzodiazepine sedative-hypnotics, such as zopiclone, offer little if any advantages in efficacy or tolerability in elderly persons. It was found that newer agents such as the melatonin agonists may be more suitable and effective for the management of chronic insomnia in elderly people. Long-term use of sedative-hypnotics for insomnia lacks an evidence base and is discouraged for reasons that include concerns about such potential adverse drug effects as cognitive impairment (anterograde amnesia), daytime sedation, motor incoordination, and increased risk of motor vehicle accidents and falls. In addition, the effectiveness and safety of long-term use of nonbenzodiazepine hypnotic drugs remains to be determined. It was concluded that further research is needed to evaluate the long-term effects of treatment and the most appropriate management strategy for elderly persons with chronic insomnia.

Special precautions: 

Alcohol should be avoided when using zopiclone, as alcohol and zopiclone enhance the effects of each other and the risk of dependence could increase.

Patients with liver disease eliminate zopiclone much slower than normal patients and in addition experience exaggerated pharmacological effects of the drug.

Zopiclone increases sway and increases the number of falls in older people as well as cognitive side effects. Falls are a significant cause of death in older people.

Patients who suffer from muscle weakness due to myasthenia gravis or have poor respiratory reserves due to severe chronic bronchitisemphysema or other lung disease, or have sleep apnoea cannot safely take zopiclone, nor can a patient with any untreated abnormality of the thyroid gland.

Overdose:

Zopiclone is sometimes used as a method of suicide. Zopiclone has a similar fatality index as benzodiazepine drugs, apart from temazepam which is particularly toxic in overdosage. Deaths have occurred from zopiclone overdose, alone or in combination with other drugs. Overdose of zopiclone may present with excessive sedation and depressed respiratory function that may progress to coma and possibly death.Zopiclone combined with alcohol,opiates, or other CNS depressants may be even more likely to lead to fatal overdoses. Zopiclone overdosage can be treated with the benzodiazepine receptor antagonist flumazenil, which displaces zopiclone from its binding site on the benzodiazepine receptor, thereby rapidly reversing the effects of zopiclone. Serious effects on the heart may also occur from a zopiclone overdose when combined with piperazine.

Death certificates show the number of zopiclone related deaths is on the rise Zopiclone when taken alone usually is not fatal, however, when mixed with alcohol or other drugs such as opioids, or in patients with respiratory, or hepatic disorders, the risk of a serious and fatal overdose increases
