The tables below contain a sample list of benzodiazepines and benzodiazepine analogs that are commonly prescribed, with their basic pharmacological characteristics, such as half-life and equivalent doses to other benzodiazepines, also listed, along with their trade names and primary uses.
A benzodiazepine can be placed into one of three groups by its elimination half-life, or time it takes for the body to eliminate half of the dose. [189] Some benzodiazepines have long-acting active metabolites , such as diazepam and chlordiazepoxide, which are metabolised into desmethyldiazepam .
An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...
Etizolam (marketed under numerous brand names) is a thienodiazepine derivative [5] which is a benzodiazepine analog. [6] The etizolam molecule differs from a benzodiazepine in that the benzene ring has been replaced by a thiophene ring and triazole ring has been fused, making the drug a thienotriazolodiazepine. [7] [8]
[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:
In addition, it has now been documented in the medical literature that one of the major metabolites of quazepam, N-desalkyl-2-oxoquazepam (N-desalkylflurazepam), which is long-acting and prone to accumulation, binds unselectively to benzodiazepine receptors, thus quazepam may not differ all that much pharmacologically from other benzodiazepines.
Flurazepam [2] (marketed under the brand names Dalmane and Dalmadorm) is a drug which is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties. It produces a metabolite with a long half-life, which may stay in the bloodstream for days. [3]
Prazepam is a benzodiazepine derivative drug developed by Warner-Lambert in the 1960s. [2] It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. [3] Prazepam, (Elimination half-life 29-224h), is a prodrug for desmethyldiazepam, (Elimination half-life 36-200h), which is responsible for the therapeutic effects ...
