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 ...
Example of a device used to screen urine for drugs. There is no line present at the benzodiazepine area, indicating a positive screen for this class of drugs. Other drugs, and the negative control (labelled "C"), are negative. Urine analysis is primarily used because of its low cost. Urine drug testing is one of the most common testing methods ...
The term benzodiazepine is the chemical name for the heterocyclic ring system (see figure to the right), which is a fusion between the benzene and diazepine ring systems. [198] Under Hantzsch–Widman nomenclature, a diazepine is a heterocycle with two nitrogen atoms, five carbon atom and the maximum possible number of cumulative double bonds.
Benzoylecgonine is the main metabolite of cocaine, formed by the liver and excreted in the urine. It is the compound tested for in most cocaine urine drug screens and in wastewater screenings for cocaine use.
Nordazepam is a partial agonist at the GABA A receptor, which makes it less potent than other benzodiazepines, particularly in its amnesic and muscle-relaxing effects. [6] Its elimination half life is between 36 and 200 hours, with wide variation among individuals; factors such as age and sex are known to impact it. [2]
In a study in rats, cross-tolerance between the benzodiazepine drug chlordiazepoxide and bretazenil has been demonstrated. [11] In a primate study bretazenil was found to be able to replace the full agonist diazepam in diazepam dependent primates without precipitating withdrawal effects, demonstrating cross tolerance between bretazenil and benzodiazepine agonists, whereas other partial ...
Pyrazolam (SH-I-04) [2] is a benzodiazepine derivative originally developed by a team led by Leo Sternbach at Hoffman-La Roche in the 1970s. [3] It has since been "rediscovered" and sold as a designer drug since 2012.
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 ...
