"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 ...
If a person is known to usually stop convulsing after only one or two diazepam doses, it may be preferable because sedative after effects will be less than if a single dose of lorazepam is given (diazepam anticonvulsant/sedative effects wear off after 15–30 minutes, but lorazepam effects last 12–24 hours). [100]
With most benzodiazepines, noticeable effects usually wear off within a few hours. Nevertheless, as long as the drug is present it will exert subtle effects within the body. These effects may become apparent during continued use or may appear as withdrawal symptoms when dosage is reduced or the drug is stopped. [citation needed]
The long-term effects of benzodiazepines and benzodiazepine dependence in the elderly can resemble dementia, depression, or anxiety syndromes, and progressively worsens over time. Adverse effects on cognition can be mistaken for the effects of old age.
A study into the effects of the benzodiazepine receptor antagonist, flumazenil, on benzodiazepine withdrawal symptoms persisting after withdrawal was carried out by Lader and Morton. Study subjects had been benzodiazepine-free for between one month and five years, but all reported persisting withdrawal effects to varying degrees.
Antidepressant discontinuation syndrome, also called antidepressant withdrawal syndrome, is a condition that can occur following the interruption, reduction, or discontinuation of antidepressant medication following its continuous use of at least a month. [5]
Used off-label to treat insomnia; Sonata – a non-benzodiazepine hypnotic; Spravato – a rapid-acting antidepressant of the NMDA receptor antagonist class; enantiomer of ketamine; Stelazine (trifluoperazine) – an antipsychotic used in the treatment of psychotic disorders, anxiety, and nausea caused by chemotherapy [2]
The central nervous system-depressant effects of benzodiazepines may make driving or operating machinery dangerous, and the elderly are more prone to these adverse effects. High single doses or repeated low doses have been reported to produce hypotonia , poor sucking, and hypothermia in the neonate , and irregularities in the fetal heart.
