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.
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 ...
Rebound insomnia, however, is more common upon discontinuation of intermediate-acting benzodiazepines than longer-acting benzodiazepines. Examples are alprazolam, estazolam, flunitrazepam, clonazepam, lormetazepam, lorazepam, nitrazepam, and temazepam. Long-acting compounds have a half-life of 40–250 hours.
Quazepam has fewer side effects than other benzodiazepines and less potential to induce tolerance and rebound effects. [14] [15] There is significantly less potential for quazepam to induce respiratory depression or to adversely affect motor coordination than other benzodiazepines. [16]
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 [6] The etizolam molecule differs from a benzodiazepine in that the benzene ring has been replaced by a thiophene ring and triazole ring has been fused, making the drug a thienotriazolodiazepine.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]
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 ...
Medazepam is a drug that is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative, and skeletal muscle relaxant properties. It is known by the following brand names: Azepamid, Nobrium, Tranquirax (mixed with bevonium), Rudotel, Raporan, Ansilan and Mezapam. [2]
In animal studies it was found to have low toxicity, although in rats evidence of pulmonary phospholipidosis occurred with pulmonary foam cells developing with long-term use of very high doses. [7] Its elimination half-life is 51–103 hours. [8] Its mechanism of action is similar to other benzodiazepines.
