Key result
Single intravenous doses of dexmedetomidine caused dose-dependent decreases in blood pressure, heart rate, and plasma norepinephrine concentration (by up to 92%) in healthy male volunteers.
Why the study?
Does intravenous dexmedetomidine alter hemodynamic parameters and plasma catecholamines in healthy male volunteers?
RCT (n=5)
Does intravenous dexmedetomidine alter hemodynamic parameters and plasma catecholamines in healthy male volunteers?
Effect estimate: up to 92% decrease in norepinephrine
Dexmedetomidine produces dose-dependent sympatholytic effects, significantly reducing blood pressure, heart rate, and plasma norepinephrine in healthy volunteers.

Warrants hemodynamic caution in use; extends sympatholytic characterization in volunteers but leaves open patient translation.
Kallio et al. (1989) conducted an RCT in Healthy volunteers (n=5). Dexmedetomidine vs. Placebo was evaluated on Hemodynamic control mechanisms (blood pressure, heart rate, plasma norepinephrine) (up to 92% decrease in norepinephrine). Single intravenous doses of dexmedetomidine caused dose-dependent decreases in blood pressure, heart rate, and plasma norepinephrine concentration (by up to 92%) in healthy male volunteers.
