Long-acting benzodiazepines with long-acting active metabolites, such as diazepam and chlordiazepoxide, are often prescribed for benzodiazepine or alcohol withdrawal as well as for anxiety if constant dose levels are required throughout the day. Shorter-acting benzodiazepines are often preferred for insomnia due to their lesser hangover effect.
Chlordiazepoxide is a long-acting benzodiazepine drug. The half-life of chlordiazepoxide is from 5 to 30 hours but has an active benzodiazepine metabolite, nordiazepam, which has a half-life of 36 to 200 hours. [31]
Effects of long-term benzodiazepine use may include disinhibition, impaired concentration and memory, depression, [19] [20] as well as sexual dysfunction. [6] [21] The long-term effects of benzodiazepines may differ from the adverse effects seen after acute administration of benzodiazepines. [22]
Escitalopram has a half-life of 27 to 32 hours. In other words, if you take a dose of 10mg of Lexapro, only 5mg will remain in your bloodstream after 27 to 32 hours. ... Benzodiazepines are not ...
[6] [33] Diazepam is the most commonly used benzodiazepine for "tapering" benzodiazepine dependence due to the drug's comparatively long half-life, allowing for more efficient dose reduction. Benzodiazepines have a relatively low toxicity in overdose. [20] Diazepam has several uses, including:
Gradual and careful reduction of the dosage, preferably with a long-acting benzodiazepine with long half-life active metabolites, such as chlordiazepoxide or diazepam, are recommended to prevent severe withdrawal syndromes from developing. Other hypnotic benzodiazepines are not recommended. [48]
Chlordiazepoxide, which also has a long half-life and long-acting active metabolites, can be used as an alternative. [145] [146] Nonbenzodiazepines are contraindicated during benzodiazepine withdrawal as they are cross tolerant with benzodiazepines and can induce dependence. [15]
Clorazepate is a long-acting benzodiazepine drug. [10] Clorazepate produces the active metabolite desmethyl-diazepam, which is a partial agonist of the GABA A receptor and has a half life of 20–179 hours; a small amount of desmethyldiazepam is further metabolised into oxazepam.
