Skills related to driving, the ability to discriminate the fusion of flickering light, and hand and foot proprioception, were measured double-blind in 34 healthy volunteers before and after three doses of i.v. diazepam. The effects of diazepam were most harmful to co-ordination. With 0.15 mg/kg, 0.30 mg/kg and 0.45 mg/kg of diazepam the impairment of co-ordinative skills was statistically signi...

Despite its pharmacological relevance, the mechanism of the development of tolerance to the action of benzodiazepines is essentially unknown. The acute sedative action of diazepam is mediated via alpha1-GABA(A) receptors. Therefore, we tested whether chronic activation of these receptors by diazepam is sufficient to induce tolerance to its sedative action. Knock-in mice, in which thealpha1-,alp...

Benzodiazepine receptor agonists are widely prescribed therapeutic agents that alter gamma-aminobutyric acid (GABA)A activity and have anxiolytic effects. Post-operative use of benzodiazepines is a risk factor delirium. Inflammatory conditions the effects benzodiazepine. We investigated effect diazepam, typical benzodiazepine anxiolytic, on changes in emotional behavior mice hole-board test aft...

We evaluated the potential utility of a group of indicators, each of which targets a particular tissue property, as indicators in the multiple-indicator dilution method to detect and to identify abnormalities in lung tissue properties resulting from lung injury models. We measured the pulmonary venous outflow concentration vs. time curves of [14C]diazepam, 3HOH, [14C]phenylethylamine, and a vas...

The objective of the current article was to review the literature and discuss the degree of evidence for various treatment strategies for status epilepticus (SE) in adults. We searched MEDLINE and EMBASE for relevant literature from 1966 to January 2005 and in the current updated version all pertinent publications from January 2005 to January 2009. Furthermore, the Cochrane Central Register of ...

We read with great interest the letter of Sodemann et al. on successful treatment of a patient with refractory absence status epilepticus (ASE) with lacosamide (LCM). In particular, Sodemann et al. reported the case of a 64-year-old male with juvenile absence epilepsy (he was on 400 mg/day lamotrigine, 400 mg/day topiramate and 2500 mg/day levetiracetam; plasma concentrations were not investiga...

Nowadays, because of increasing employment of swine for experimental studies and medical training, it is hopeful to investigate novel and effective anaesthetic protocols for preserving the animal welfare in medical investigation and concurrently improving the quality of research. Therefore, the aim of this study was to investigate a novel and effective anaesthetic protocol in swine undergoing m...

The solubility enhancement of diazepam and nitrazepam in water was analyzed depending on temperature and amount of α-cyclodextrin (α-CD), β-cyclodextrin (β-CD) and 2-hydroxypropyl-β-cyclodextrin (2-HP-β-CD). The interactions of drug-cyclodextrin in solution were investigated by the phase-solubility analysis. Diazepam (nitrazepam) content in aqueous complexation medium was analyzed UV spectropho...
