Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder, characterized by motor symptoms, postural instability, personality changes, and cognitive impairment. There is no effective treatment for this disorder. Reduced neurotransmission of GABA in the striatum and globus pallidus may contribute to the symptoms of motor and cognitive symptoms seen in PSP. Zolpidem is a GA...

Binge-like ethanol treatment of septal neurons blunts GABAAR-mediated miniature postsynaptic currents (mPSCs), suggesting it arrests synaptic development. Ethanol may disrupt postsynaptic maturation by blunting feedback signaling through immature GABAARs. Here, the impact of ethanol on the sensitivity of mPSCs to zolpidem, zinc and 3alpha-hydroxy-5alpha-pregnan-20-one (3alpha-OH-DHP) was tested...

trial of the effects of prolonged-release melatonin, temazepam and zolpidem on slow-wave activity during sleep in healthy people. J Psychopharmacol. Abstract Current pharmacological treatments for insomnia include benzodiazepine and non-benzodiazepine hypnotics targeting GABA A receptors, as well as agonists of the melatonin receptors MT1 and MT2. Melatonin, temazepam and zolpidem are thought t...

OBJECTIVE Gabapentin is being investigated as a potential treatment for occasional disturbed sleep. This study assessed the pharmacokinetics and tolerability of gabapentin 500 mg and the commonly prescribed sedative/hypnotic zolpidem tartrate 10 mg, administered separately and in combination. METHODS Forty healthy participants (19 male, 21 female) were randomized into this three-period crosso...

STUDY OBJECTIVES To determine if systemic administration of selected sedative-hypnotics that modulate the function of the y-amino-butyric acid-A (GABAA) receptor can: (i) delay arousal thereby allowing genioglossus (GG) activity to increase more in response to respiratory stimulation during sleep, (ii) also cause the robust increase in GG activity during undisturbed sleep recently observed with...

BACKGROUND Zolpidem is a non-benzodiazepine medication which selectively affects GABA A receptors and treats insomnia. There are numerous reports of psychosis following the consumption of zolpidem all of which recovered after stopping the medication. CASE REPORT A 27 year old male law student, who was treated with 10 mg zolpidem due to insomnia, increased the dosage to 500 mg during 3 months....

A novel, simple and economic reverse phase high performance liquid chromatography (RP-HPLC) method has been developed for the estimation of zolpidem tartrate in bulk and tablet dosage form with greater precision and accuracy. Separation was achieved on C18 column (250X4.6mm i.d.,5μm) in isocratic mode using methanol and acetonitrile in the ratio 50:50 (v/v) as mobile phase, pumped in to the col...

Zolpidem belongs to a new class of hypnotic agents, chemically distinct from the pre-existing ones, and has a unique neuropharmacological profile. It induces sedative/hypnotic effects in rodents at doses much lower than those for anticonvulsant and myorelaxant activities. Clinically, zolpidem is indicated for the short term treatment of insomnia. It has a short half-life (2.4h), with no active ...

In this study, we compared the effects of Type I benzodiazepine receptor-selective agonists (zolpidem, quazepam) and Type I/II non-selective agonists (zopiclone, triazolam, nitrazepam) with either an ultra-short action (zolpidem, zopiclone, triazolam) or long action (quazepam, nitrazepam) on motor coordination (rota-rod test) and muscle relaxation (traction test) following the recovery from thi...

OBJECTIVE Complex sleep behaviors (CSBs) are classified as "parasomnias" in the International Classifcation of Sleep Disorders, Second Edition (ICSD-2). To realize the potential danger after taking two short-acting Z-hypnosedative drugs, we estimated the incidence of CSBs in nonpsychotic patients in Taiwan. METHODS Subjects (N = 1,220) using zolpidem or zopiclone were enrolled from the psychi...
