Research ArticleOpen accessIn the abstractQuantification of Zolpidem in Canine PlasmaMario Giorgi, Alessandra Gavazza, Hyoin YunProblem statement: Zolpidem is a non-benzodiazepine hypnotic agent currently used in human medicine. In contrast to benzodiazepines, zolpidem preferentially binds with the GABAA complex ϖ1 receptors while poorly interacting with the other ϖ receptor complexes. Recent studies have suggested that ZP may be used to initiate sedation and diminish severe anxiety responses in dogs. The aim of the present study … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 19 Mar 2012 · 7,908 accessesView PDFCite
