Benzodiazepines uses are many. Preoperative medication for anxiolysis and sedation is one where it finds its usage.
Midazolam has replaced diazepam as the most commonly administered benzodiazepine in the preoperative period for preoperative medication and intravenous (IV) sedation.
Furthermore, the context-sensitive half-times for diazepam and lorazepam are prolonged; and so they are used where prompt recovery is not required, particularly in critical care set up.
The chemical structure composed of a benzene ring fused to a seven-membered diazepine ring is the common representation.
The physicochemical properties, potency and metabolites which benzodiazepines uses depend on the substitutions at various positions of the ring.
