Zopiclone (Imovance), 4-methyl-1-piperzinecarboxylic acid 6-(5-chloro-2- pyridinyl)-6,7-dihydro-7-oxo-5H-pyrrolo[3,4-b]pyrazin-5-yl ester (Figure 1) is one of the non benzodiazepine sedative-hypnotics of the cyclopyrrolone class, sold by Rhone-Poulene Company in France since 1987. Although structurally unrelated to benzodiazepines, its pharmacological profile is similar, exhibiting sedative-hypnotic, anxiolytic, myorelaxant, and anticonvulsant activity.[1] Other than the first generation barbiturates and the second-generation benzodiazepines, zopiclone, which is widely used in Europe as well as other regions worldwide,[2,3] as a representative of the third generation sedative-hypnotic drugs, has been shown to be free from residual effects on performance and psychological function the day after intake and from the risks of accumulation because of its short elimination half-life (3.5 to 6.5 hours).[3,4] It is indicated for the short term treatment of insomnia, transient, situational or chronic insomnia, and insomnia secondary to psychiatric disturbances.[3]
