Vertical ionization energies (VIEs) of medazepam and nordazepam and of their molecular subunits have been calculated with the electron propagator method in the P3/CEP-31G* approximation. Vertical electron affinities (VEAs) have been obtained with a ΔSCF procedure at the DFT-B3LYP/6-31+G* level of theory. Excellent correlations have been achieved between IEcalc and IEexp allowing reliable assignment of the ionization processes. -

Moreover, some of benzodiazepines are widely used as an anti-depressive and sedative drugs, and also as anti-epileptic drugs and in some cases can be useful as an adjunct treatment in refractory epilepsies or anti-alcoholic therapy. High-performance liquid chromatography (HPLC) methods, thin-layer chromatography (TLC) methods, gas chromatography (GC) methods, capillary electrophoresis (CE) methods and some of spectrophotometric and spectrofluorometric methods were developed and have been extensively applied to the analysis of number of benzodiazepine derivative drugs (BDZs) providing reliable and accurate results. The available chemical methods for the determination of BDZs in biological materials and pharmaceutical formulations are reviewed in this work.

They are based explicitly on the available evidence and presented as recommendations to aid clinical decision making for practitioners alongside a detailed review of the evidence. A consensus meeting, involving experts in the treatment of these disorders, reviewed key areas and considered the strength of the evidence and clinical implications. The guidelines were drawn up after feedback from participants. The guidelines primarily cover the pharmacological management of withdrawal, short- and long-term substitution, maintenance of abstinence and prevention of complications, where appropriate, for substance abuse or harmful use or addiction as well management in pregnancy, comorbidity with psychiatric disorders and in younger and older people.

Calculating Equivalent Doses of Oral Benzodiazepines
Calculating equivalent doses of oral benzodiazepines Background Benzodiazepines are the most commonly used anxiolytics and hypnotics (1). There are major differences in potency between different benzodiazepines and this difference in potency is important when switching from one benzodiazepine to another (2). Benzodiazepines also differ markedly in the speed in which they are metabolised and eliminated. With repeated daily dosing accumulation occurs and high concentrations can build up in the body (mainly in fatty tissues) (2). The degree of sedation that they induce also varies, making it difficult to determine exact equivalents (3). Answer Advice on benzodiazepine conversion NB: Before using Table 1, read the notes below and the Limitations statement at the end of this document. Switching benzodiazepines may be advantageous for a variety of reasons, e.g. to a drug with a different half-life pre-discontinuation (4) or in the event of non-availability of a specific benzodiazepine. With relatively short-acting benzodiazepines such as alprazolam and lorazepam, it is not possible to achieve a smooth decline in blood and tissue concentrations during benzodiazepine withdrawal. These drugs are eliminated fairly rapidly with the result that concentrations fluctuate with peaks and troughs between each dose. It is necessary to take the tablets several times a day and many people experience a "mini-withdrawal", sometimes a craving, between each dose. For people withdrawing from these potent, short-acting drugs it has been advised that they switch to an equivalent dose of a benzodiazepine with a long half life such as diazepam (5). Diazepam is available as 2mg tablets which can be halved to give 1mg doses.
