Table 1 tissue concentrations of dexmedetomidine in guinea pig tracheal rings (n = 5 animals). Guinea pig tracheal rings were incubated for 30 mins in buffer with 1–100 μM dexmedetomidine. Following extraction, average penetrating tissue concentrations of dexmedetomidine were deteremined by HPLC – MS/MS
