How To Konw About Zopiclone?
Zopiclone, as traditionally sold worldwide, is a racemic mixture of two stereoisomers, only one of which is active. In 2005, the pharmaceutical company Sepracor of Marlborough, Massachusetts began marketing the active stereoisomer eszopiclone under the name Lunesta in the United States. This had the consequence of placing what is a generic drug in most of the world under patent control in the United States, although it is expected to be available in generic form in that country by 2010. It is already available off-patent in a number of European countries as well as Brazil. The eszopiclone/zopiclone difference is in the dosage-the strongest eszopiclone derivative dosage contains 3mg of the therapeutic stereoisomer, whereas, the highest zopiclone dosage (7.5mg) contains 3.75mg of the active stereoisomer. The two agents have not yet been studied in head-to-head clinical trials to determine the existence of any potential clinical differences (efficacy, side effects, developing dependence on the drug, safety, etc).
