Used for procedural sedation, induction and maintenance of general anesthesia, particularly in procedures requiring short-term sedation where rapid recovery is desired.
Binds to GABA A receptors in the brain, enhancing the effects of gamma-aminobutyric acid (GABA), the main inhibitory neurotransmitter, resulting in sedation, anxiolysis, and amnesia.
May cause respiratory depression, especially when combined with opioids or other CNS depressants. Requires monitoring of vital signs during administration. Has a carboxylic acid metabolite (CNS7054) with significantly lower receptor affinity, contributing to its short-acting profile.
