The active ingredient in the blue zopiclone 7.5 mg, which is a prescription drug within the hypnotic medicine family, is Zopiclone. A short-term treatment for all types of insomnia, including anxiety-induced insomnia (difficulty falling asleep, waking up during the night, or early in the morning), is Imovane (Zopiclone). The way blue zopiclone pills work is by strongly attaching to central receptors of the GABA macromolecular complex. This complex controls how fast chloride channels open. By raising GABA activity in the brain, it effectively produces sedative, hypnotic, anxiolytic, and anticonvulsant actions.
