Background and purpose: Intentional drug poisoning is one of the most common methods of suicide attempt. The purpose of this study was to determine the demographic characteristics of suicide attempters and identifying the pattern of intentional drug poisoning. Materials and methods: We conducted a descriptive-analytical study in which data was collected from the medical records of suicide at...
Clobazam (CLB), a 1,5-benzodiazepine (BZD), was FDA-approved in October 2011 for the adjunctive treatment of seizures associated with Lennox-Gastaut syndrome (LGS) in patients 2 years and older. BZDs exert various CNS effects through allosteric modulation of GABAA receptors. The structurally distinct, 1,4-BZD clonazepam (CLN) is also approved to treat LGS. The precise mechanisms of action and c...
The effects of m-chlorophenylpiperazine (m-CPP) (0.5 mg/kg) on sleep architecture and behavior were examined in six healthy volunteers following a single oral dose of the drug in a randomized, double-blind, placebo-controlled study. m-CPP reduced total sleep time (TST) and sleep efficiency in all subjects. Slow-wave sleep (SWS) and rapid-eye-movement (REM) sleep were decreased and stage 1 sleep...
OBJECTIVES Kadsura longipedunculata (KL) has been widely used for the treatment of insomnia in traditional Chinese medicine. The aim of this study was to explore the mechanism of the sedative and hypnotic effects of KL. MATERIALS AND METHODS The content of KL was evaluated by HPLC-TOF-MS, and a potential target was found and used to construct its 3D structure to screen for potential ligands a...
OBJECTIVES An estimated 6%-10% of US adults took a hypnotic drug for poor sleep in 2010. This study extends previous reports associating hypnotics with excess mortality. SETTING A large integrated health system in the USA. DESIGN Longitudinal electronic medical records were extracted for a one-to-two matched cohort survival analysis. SUBJECTS Subjects (mean age 54 years) were 10 529 patie...
Neurosteroids are synthesized within the brain and act as endogenous anxiolytic, anticonvulsant, hypnotic, and sedative agents, actions that are principally mediated via their ability to potentiate phasic and tonic inhibitory neurotransmission mediated by γ-aminobutyric acid type A receptors (GABAARs). Although neurosteroids are accepted allosteric modulators of GABAARs, here we reveal they exe...
GABA(A) receptors are pentameric ligand-gated ion channels involved in fast inhibitory neurotransmission and are allosterically modulated by the anxiolytic, anticonvulsant, and sedative-hypnotic benzodiazepines. Here we show that the prokaryotic homolog ELIC also is activated by GABA and is modulated by benzodiazepines with effects comparable to those at GABA(A) receptors. Crystal structures re...
