BACKGROUND Panax vietnamensis Ha et Grushv. or Vietnamese ginseng (VG) is a recently discovered ginseng species. Studies on its chemical constituents have shown that VG is remarkably rich in ginseng saponins, particularly ocotillol saponins. However, the psychopharmacological effects of VG have not been characterized. Thus, in the present study we screened the psychopharmacological activities o...

Abstract Introduction Cognitive-behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment, but sedative-hypnotic medications are often used first, despite contraindications and risk of misuse. This study assessed change in sedative/hypnotic use/dosage patients with chronic treated Somryst® (tested as SHUTi), a prescription digital therapeutic (PDT) delivering CBT-I. Method...

BACKGROUND Etomidate is a sedative hypnotic that is often used in critically ill patients because it provides superior hemodynamic stability. However, it also binds with high affinity to 11beta-hydroxylase, potently suppressing the synthesis of steroids by the adrenal gland that are necessary for survival. The authors report the results of studies to define the pharmacology of (R)-ethyl 1-(1-ph...

Background Chronic insomnia is a prevalent and debilitating disorder managed in Australian general practice. The most effective recommended first-line treatment for cognitive behavioural therapy. This has been translated to condensed brief therapy (BBTi), which suitable delivery the practice setting. There evidence that BBTi improves insomnia, daytime functioning quality of life, with effects p...

GABA(A) receptors have been implicated in mediating several acute effects of ethanol including anxiolysis, ataxia, sedation/hypnosis, and anticonvulsant activity. Ethanol sensitivity of neurons has been associated with expression of alpha1 subunit-containing receptors. The objective of this study was to determine the contribution of alpha1 subunit containing receptors to ethanol responses in co...

Dexmedetomidine, the D-enantiomer of medetomidine, is among the most potent sedative drugs known. It is also one of the best understood in terms of its molecular and cellular mechanisms. Its sedative (and probably its neuroprotective) effects are mediated by subtype A of the α2 adrenergic receptor, a G-protein-coupled receptor. Acting as an agonist at this receptor, dexmedetomidine causes numer...

The nutritional significance of essential amino acids, as well as non-essential amino acids, is well documented in poultry production with regards to growth performance and protein accretion. However, the function of amino acids in the stress response is still unclear. L-Pipecolic acid, a L-lysine metabolite in the brain, induced a hypnotic and sedative effect acting via the γaminobutyric acid ...

OBJECTIVE Although widely used in the general population, sleeping pills and minor tranquilizers, also known as antianxiety agents, have been associated with undesirable outcomes. Reports about the association of these drugs with an elevated mortality rate are inconsistent and controversial. This study was designed to assess the mortality hazard associated with anxiolytic and hypnotic drug use ...

Insomnia is the most common sleep disorder, and is often associated with significant medical, psychological, and social disturbances. Conventional medical treatment for insomnia includes psychological and pharmacological approaches; however, long-term use of frequently prescribed medications can lead to habituation and problematic withdrawal symptoms. Therefore, herbal and other natural sleep a...
