The blood-level decline of the parent drug was biphasic, with the short half-life ranging from 0.4 to 0.6 hours and the terminal half-life from 3.5 to 18.4 hours (mean 8.8 hours), depending on the study population and method of determination. [62] Temazepam has very good bioavailability, with almost 100% being absorbed following being taken by ...
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.
Flutemazepam was initially first synthesized in 1965, [1] but was not further described until a team at Stabilimenti Chimici Farmaceutici Riuniti SpA in the mid-1970s. [2] [3] It is a short-acting (9–25 hr elimination half-life) fluorinated analogue of temazepam that has powerful hypnotic, sedative, amnesiac, anxiolytic, anticonvulsant and skeletal muscle relaxant properties.
Desmethyldiazepam has a half-life of 36–200 hours, and flurazepam, with the main active metabolite of desalkylflurazepam, with a half-life of 40–250 hours. These long-acting metabolites are partial agonists. [6] [145] Short-acting compounds have a median half-life of 1–12 hours.
A 1993 British study found flurazepam and temazepam to have the highest number of deaths per million prescriptions among medications commonly prescribed in the 1980s. Flurazepam, now rarely prescribed in the United Kingdom and Australia, had the highest fatal toxicity index of any benzodiazepine (15.0) followed by Temazepam (11.9), versus 5.9 ...
Clorazepate is prescribed principally in the treatment of alcohol withdrawal and epilepsy, although it is also a useful anxiolytic because of its long half-life. 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.
It is the dimethyl carbamate ester of temazepam, a metabolite of diazepam. [3] While it possesses anxiolytic , anticonvulsant , skeletal muscle relaxant and hypnotic properties [ 4 ] it differs from other benzodiazepines in that its anxiolytic properties are particularly prominent but has comparatively limited anticonvulsant , hypnotic and ...
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] The half-life of chlordiazepoxide increases significantly in the elderly, which may result in prolonged action as well as accumulation of the drug during repeated administration.
