Zopiclone is a sedative-hypnotic medication primarily used to treat short-term insomnia. It works by enhancing the effects of the neurotransmitter GABA in the brain, which helps induce and maintain sleep. Typically prescribed for short durations, Zopiclone helps individuals fall asleep faster and stay asleep longer. It is effective for sleep disorders, but should be used under medical supervision due to potential side effects like drowsiness, dizziness, and a risk of dependency with long-term use. Zopiclone is usually taken just before bedtime and should not be used with alcohol or other depressants.
