BACKGROUND/AIM Diazepam is a benzodiazepine anxyolitic. Metabolism of diazepam takes place in liver which generates pharmacologically active metabolites N-desmethyldiazepam, temazepam and oxazepam. The aim of this study was to develop and validate the method of liquid chromatographymass spectrometry (LC-MS) for separation and determination of diazepam and its active metabolites in the serum of ...

Abstract Objective: This study evaluates the role of oral sedation, using 5 mg diazepam, on postoperative sequelae (Pain, trismus and swelling) following impacted mandibular third molar surgery. Materials methods: is a randomised control involving 100 patients whose anxiety levels were assessed with Modified Dental Anxiety Scale (MDAS) just before drug administration thirty minutes after admini...

BACKGROUND Behavioral effects of benzodiazepines following repeated exposure vary according to the intrinsic efficacy of the benzodiazepine studied, treatment schedule and the behavioral parameters evaluated. METHODS We applied the behavioral paradigms of spontaneous locomotor activity, elevated plus maze and grip strength to investigate the sedative, anxiolytic and myorelaxant effect of acut...

Different subtypes of GABAA (gamma-aminobutyric acid A) receptors, through their specific regional and cellular localization, are involved in the manifestation various functions, both at central peripheral levels. We hypothesized that non-neuronal receptors expressed on blood vessels, which positive allosteric modulators exhibit vasodilatory effects. This study two parts: one to determine prese...

Diazepam is metabolized by CYP2C19 and CYP3A4 in the liver. CYP2C19 shows genetic polymorphism associated with the poor metabolizer (PM) and extensive metabolizer (EM) phenotypes. The aim of this study was to assess the effect of diltiazem, a CYP3A4 inhibitor, on pharmacokinetics and dynamics of diazepam in relation to CYP2C19 genotype status. Thirteen healthy volunteers (eight EMs and five PMs...

[3H]Diazepam appears to bind specifically to a single, saturable, binding site located on rat brain membranes, with an affinity constant near 3 nM at pH 7.4. Specific binding constitutes more than 90% of total binding at 0 degrees and less than 10% of total binding at 37 degrees. Arrhenius plots suggest a sharp conformational change in the diazepam receptor near 18 degrees. Mitochondrial fracti...

OBJECTIVE Oxidative stress is a likely molecular mechanism in long-term diazepam administration. The benefits of antioxidants (melatonin and vitamin C) against diazepam-induced cell proliferation, DNA synthesis and oxidative damage were investigated in this study. MATERIALS & METHODS Four equal-sized groups of male rats [control, diazepam (3 mg/kg), diazepam plus melatonin (5 mg/kg) and diaze...

OBJECTIVE To review the aetiology and treatment of status epilepticus and present a practical approach to its management. DATA SOURCES A review of studies reported from 1966 to 1998 and identified through a MEDLINE search of the English-language literature on metabolic and toxic seizures and status epilepticus. SUMMARY OF REVIEW Status epilepticus describes a condition of prolonged or repet...
