Zopiclone
Introduction: What is Zopiclone?
Zopiclone is a prescription sedative-hypnotic medication used for the short-term treatment of insomnia. It helps individuals fall asleep faster, stay asleep longer, and experience fewer awakenings during the night. Zopiclone is classified as a non-benzodiazepine hypnotic and is part of the ?Z-drug? class, which also includes zolpidem and zaleplon. This medicine is typically available in tablet form. It may be sold under brand names like Imovane? and Zimovane?.
Uses of Zopiclone
Zopiclone is prescribed primarily for:
- Short-term treatment of insomnia
- Difficulty falling asleep (sleep-onset insomnia)
- Frequent night awakenings
- Early morning awakening
Zopiclone is recommended for short-term use only (usually 2?4 weeks) due to its potential for tolerance, dependence, and withdrawal symptoms.
How Does It Work?
Zopiclone acts on GABAA receptors in the brain by enhancing the effect of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). This leads to:
- Sedative and hypnotic effects
- Relaxation of the central nervous system
- Reduced time to sleep onset and increased total sleep duration
While not chemically a benzodiazepine, Zopiclone has similar effects on sleep and brain activity.
Dosage and Administration
Zopiclone is available in 3.75 mg and 7.5 mg tablets.
Typical Adult Dosage:
- Initial dose: 3.75 mg or 5 mg at bedtime (for elderly or hepatic impairment patients)
- Usual dose: 7.5 mg once daily at bedtime
Take Zopiclone just before bedtime. Avoid taking it earlier in the evening, as it may cause next-day drowsiness.
Side Effects of Zopiclone
Common Side Effects:
- Drowsiness or sedation (especially next morning)
