Leo Sternbach (May 7, 1908 – September 28, 2005) was a Polish American chemist who is credited with first synthesizing benzodiazepines, the main class of minor tranquilizers. [ 1 ] Background and family
A 1999–2005 Australian police survey of detainees reported preliminary findings that self-reported users of benzodiazepines were less likely than non-user detainees to work full-time and more likely to receive government benefits, use methamphetamine or heroin, and be arrested or imprisoned. [223]
In 1907 Alfred Bertheim synthesized Arsphenamine, the first man-made antibiotic. In 1927 Erik Rotheim patented the first aerosol spray can. In 1933 Robert Pauli Scherer created a method to develop softgels. William Roberts studies about penicillin were continued by Alexander Fleming, who in 1928 concluded that penicillin had an antibiotic ...
Benzodiazepines impair learning and memory via their action on benzodiazepine receptors, which causes a dysfunction in the cholinergic neuronal system in mice. [16] It was later found that impairment in learning was caused by an increase in benzodiazepine/GABA activity (and that benzodiazepines were not associated with the cholinergic system). [17]
Flunitrazepam, sold under the brand name Rohypnol among others, [3] is a benzodiazepine used to treat severe insomnia and assist with anesthesia. [4] As with other hypnotics, flunitrazepam has been advised to be prescribed only for short-term use or by those with chronic insomnia on an occasional basis.
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 ...
During this time, a total of 52% of drug forgeries were for benzodiazepines, suggesting they were a major prescription drug class of abuse. [ 40 ] However, due to its slow rate of absorption and its slow onset of action, [ 30 ] oxazepam has a relatively low potential for abuse compared to some other benzodiazepines, such as temazepam ...
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 ...
