Dexmedetomidine is a highly selective alpha-2 adrenergic receptor agonist used for sedation in intensive care settings and during procedural sedation. It is approved and widely used for sedation of mechanically ventilated adults and can be used in perioperative settings. It has sedative, anxiolytic, and analgesic properties with minimal respiratory depression.
Pharmacokinetics
Pharmacokinetics reported from healthy adult subjects undergoing elective surgery; typical intravenous administration.
