A study in 2000 found that long-term benzodiazepine therapy does not result in brain abnormalities. [75] Withdrawal from high-dose use of nitrazepam anecdotally was alleged in 2001 to have caused severe shock of the whole brain with diffuse slow activity on EEG in one patient after 25 years of use. After withdrawal, abnormalities in hypofrontal ...
"Time to peak" refers to when maximum levels of the drug in the blood occur after a given dose. Benzodiazepines generally share the same pharmacological properties, such as anxiolytic, sedative, hypnotic, skeletal muscle relaxant, amnesic, and anticonvulsant effects. Variation in potency of certain effects may exist amongst individual ...
High doses of many shorter-acting benzodiazepines may also cause anterograde amnesia and dissociation. [4] These properties make benzodiazepines useful in treating anxiety, panic disorder, insomnia, agitation, seizures, muscle spasms, alcohol withdrawal and as a premedication for medical or dental procedures.

Many drivers had blood levels far exceeding the therapeutic dose range, suggesting a high degree of potential for misuse of benzodiazepines, zolpidem, and zopiclone. [116] In Northern Ireland, in cases where drugs were detected in samples from impaired drivers who were not impaired by alcohol, benzodiazepines were found in 87% of cases ...
Deaths from single-drug benzodiazepine overdoses occur infrequently, [3] particularly after the point of hospital admission. [4] 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.
Nordazepam is among the longest lasting (longest half-life) benzodiazepines, and its occurrence as a metabolite is responsible for most cumulative side-effects of its myriad of pro-drugs when they are used repeatedly at moderate-high doses; the nordazepam metabolite oxazepam is also active (and is a more potent, full BZD-site agonist), which ...
The normal starting dosage range of clorazepate is 15 to 60 mg per day. The drug is to be taken two to four times per day. Dosages as high as 90 to 120 mg per day may be used in the treatment of acute alcohol withdrawal. In the United States and Canada, clorazepate is available in 3.75, 7.5, and 15 mg capsules or tablets.
Temazepam is a drug with a high potential for misuse. [66] Benzodiazepines have been abused orally and intravenously. Different benzodiazepines have different abuse potential; the more rapid the increase in the plasma level following ingestion, the greater the intoxicating effect and the more open to abuse the drug becomes.
