How does it work?
Zimovane contains the active ingredient zopiclone, which is a type of medicine called a non-benzodiazepine hypnotic. It acts in the brain to aid sleep.
Zopiclone works by acting on receptors in the brain called GABA receptors. This causes the release of a neurotransmitter called GABA in the brain.
GABA is a neurotransmitter that acts as a natural ‘nerve-calming’ agent. It helps keep the nerve activity in the brain in balance, and is involved in inducing sleepiness, reducing anxiety and relaxing muscles.
Zopiclone can be used as a short-term treatment for insomnia. This includes difficulty falling asleep, waking in the night, waking early in the morning, sleeping problems related to psychiatric disorders and sleeping problems that are causing severe distress.
Zopiclone decreases the time taken to fall asleep and night-time awakenings, as well as increasing the total amount of time spent sleeping. However, it is only suitable for short-term treatment of insomnia (up to four weeks), as when used for longer periods it has a potential for dependence.
The medicine should be taken shortly before going to bed for the night.
