Fig. 4From: Intranasal epinephrine effects on epinephrine pharmacokinetics and heart rate in a nasal congestion canine modelEffect of IN Epinephrine on Epinephrine Plasma Concentrations After IN Histamine or Saline. Group average epinephrine concentration-time profiles are plotted for the histamine and saline groups. Immediately after IN epinephrine, the average epinephrine plasma concentration was greater in the histamine group versus the saline group. Data represent mean ± SD. IN, intranasalBack to article page
