Pharmacology
Dexmedetomidine is an alpha-2 adrenergic receptor agonist whose mechanism of action in acute agitation is thought to involve activation of presynaptic alpha-2 adrenergic receptors; it also exhibits concentration-dependent QT prolongation.
Brexpiprazole is an atypical antipsychotic whose efficacy may be mediated through partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors combined with antagonist activity at serotonin 5-HT2A receptors; the exact mechanism of action in the approved indications is unknown.
