Which of the following used as preanesthetic medication causes longest amnesia?
The longest amnesia is produced by lorazepam although half-life of lorazepam (15 hours) is shoer than diazepam (36 hours) and this is probably because of its strong receptor binding potential. Its relatively potent amnesic effect, with its anxiolytic and sedative effects, makes lorazepam useful as premedication.
Midazolam
Diazepam
Lorazepam
Flunitrazepam
