Zopiclone
A hypnotic of the cyclopyrrolone family, one of the so-called Z-drugs, developed in France and introduced in 1986 for the short-term treatment of insomnia: it acts at the same receptor site as benzodiazepines. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards and other impurities.
Did you know?It is a mixture of two mirror-image forms of the same molecule, but only one is active: that form, isolated on its own, became a separate medicine, eszopiclone.
