The aim of this study is to investigate the pharmacokinetics of subcutaneously administered
dexmedetomidine in healthy volunteers. The absolute bioavailability of subcutaneously
administered dexmedetomidine will be calculated. In addition, the investigators will report
the effects of subcutaneously administered dexmedetomidine on plasma catecholamine levels,
vital signs such as systemic blood pressure, heart rate and sedation. The investigators will
also monitor the local and systemic safety and tolerability of subcutaneously administered
dexmedetomidine.
