title: [Pharmacological profile and clinical effect of zolpidem (Myslee tablets), a hypnotic agent].
abstract: Zolpidem is a non-benzodiazepine hypnotic agent with a chemical structure of imidazopyridine. In vitro and in vivo binding studies, zolpidem exhibits selectivity to omega 1 receptors (GABAA-receptor subtypes containing alpha 1 subunits). Unlike benzodiazepines, zolpidem produces sedative effects in preference to anxiolytic, anticonvulsant and myorelaxant effects in behavioral experiments using mice. Double-blind comparative studies with reference drugs such as triazolam and zopiclone show that zolpidem is an effective and highly safe drug for the treatment of insomnia. In addition, zolpidem does not produce next-day residual effects, rebound insomnia and tolerance. This clinical profile of zolpidem may be related to its selectivity and high intrinsic activity for omega 1 receptors.
