Finally, note that the benzodiazepine core is a privileged scaffold, which has been used to derive drugs with diverse activity that is not limited to the GABA A modulatory action of the classical benzodiazepines, [60] such as devazepide and tifluadom, however these have not been included in the list below. 2,3-benzodiazepines such as tofisopam ...
Benzodiazepines, like many other sedative hypnotic drugs, cause apoptotic neuronal cell death. However, benzodiazepines do not cause as severe apoptosis to the developing brain as alcohol does. [105] [106] [107] The prenatal toxicity of benzodiazepines is most likely due to their effects on neurotransmitter systems, cell membranes and protein ...
Men and women are equally likely to use benzodiazepines recreationally. The report found that alprazolam is the most common benzodiazepine for recreational use, followed by clonazepam, lorazepam, and diazepam. The number of emergency department visits due to benzodiazepines increased by 36% between 2004 and 2006. [117]
Many of the pharmacologically active "classical" benzodiazepine drugs contain the 5-phenyl-1H-benzo[e] [1,4]diazepin-2(3H)-one substructure (see figure to the right). [192] Benzodiazepines have been found to mimic protein reverse turns structurally, which enable them with their biological activity in many cases. [193] [194]
A survey of doctors in Senegal found that many doctors feel that their training and knowledge of benzodiazepines is, in general, poor; a study in Dakar found that almost one-fifth of doctors ignored prescribing guidelines regarding short-term use of benzodiazepines, and almost three-quarters of doctors regarded their training and knowledge of ...
The use of benzodiazepines by street-drug abusers was part of a polydrug abuse pattern, but many of those entering treatment facilities were declaring temazepam as their main drug of abuse. Temazepam was the most commonly used benzodiazepine in a study, published 1994, of injecting drug users in seven cities, and had been injected from ...
A meta-analysis found cognitive impairments in many areas due to benzodiazepine use show improvements after six months of withdrawal, but significant impairments in most areas may be permanent or may require more than six months to reverse. [128] Protracted symptoms continue to fade over a period of many months or several years.
However, combinations of high doses of benzodiazepines with alcohol, barbiturates, opioids or tricyclic antidepressants are particularly dangerous, and may lead to severe complications such as coma or death. In 2013, benzodiazepines were involved in 31% of the estimated 22,767 deaths from prescription drug overdose in the United States. [5]
