Drug selection
Psychotropic or sedative drugs are used to alter a patient’s psychological state in order to relieve their distress, although this frequently occurs at the expense of altering the consciousness level.

The drugs used in this situation can be classified as:
- anxiolytic sedatives, e.g., midazolam, lorazepam
- antipsychotics (neuroleptics), e.g., haloperidol, levomepromazine (North America: methotrimeprazine)
- sedative anti-epileptics, e.g., phenobarbital
- general anesthetics, e.g., propofol
