Group Intervention Description Primatene Mist, E004 Epinephrine (0.125 mg/inhalation) Participants who dosed with Primatene Mist. Epinephrine Injection Auto-Injector (Generic of EpiPen) Epinephrine Injection Auto-Injector (0.3mg/0.3mL) Participants who were dosed with an Epinephrine Injection Auto-Injector. Albuterol HFA Albuterol Sulfate (0.09 mg/inhalation) Participants who dosed with Albuterol HFA.
- Primary Outcome Measures
Name Time Method C[Max], Maximum Plasma Concentration of Albuterol or Epinephrine Samples were drawn at 30 minutes pre-dose and at 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 25, 30, 40, 50, 60, 70, 80, 90, 120 minutes, 4, 6, 8, 12, 18, and 24 hours post-dose. Pharmacokinetic (PK) blood samples will be collected starting 30 minutes before dose and until 24 hours after dose. Plasma will be isolated for analyzing the concentrations of Albuterol and Epinephrine. C\[max\] will be obtained directly from the plot of PK curve.
AUC(0-tm)_TOT, Area Under the Curve (AUC) of Total (Exogenous and Endogenous, if Available) Active Product Ingredient (API) From Time 0 to Time (tm) Samples were drawn at 30 minutes pre-dose and at 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 25, 30, 40, 50, 60, 70, 80, 90, 120 minutes, 4, 6, 8, 12, 18, and 24 hours post-dose. Pharmacokinetic (PK) blood samples will be collected starting 30 minutes before dose and until 24 hours after dose. Plasma will be isolated for analyzing the concentrations of Albuterol and Epinephrine. AUC(0-tm)_TOT will be calculated with the trapezoid method. Time tm is defined as the time after C\[max\] is reached where API concentration is reduced to the levels of the same day baseline.
AUC(0-inf), Area Under the Curve (AUC) of Albuterol or Epinephrine From Time 0 to Infinity Samples were drawn at 30 minutes pre-dose and at 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 25, 30, 40, 50, 60, 70, 80, 90, 120 minutes, 4, 6, 8, 12, 18, and 24 hours post-dose. Pharmacokinetic (PK) blood samples will be collected starting 30 minutes before dose and until 24 hours after dose. Plasma will be isolated for analyzing the concentrations of Albuterol and Epinephrine. AUC(0-inf) will be calculated with the extrapolation method.
AUC(0-tm)_DE, Area Under the Curve (AUC) of Exogenous Active Product Ingredient (API) From Time 0 to Time (tm) Samples were drawn at 30 minutes pre-dose and at 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 25, 30, 40, 50, 60, 70, 80, 90, 120 minutes, 4, 6, 8, 12, 18, and 24 hours post-dose. Pharmacokinetic (PK) blood samples will be collected starting 30 minutes before dose and until 24 hours after dose. Plasma will be isolated for analyzing the concentrations of Albuterol and Epinephrine. AUC(0-tm)_DE will be calculated with the trapezoid method. Time tm is defined as the time after C\[max\] is reached where API concentration is reduced to the levels of the same day baseline.
- Secondary Outcome Measures
Name Time Method t[Max], Time at Which Maximum Plasma Concentration of Albuterol or Epinephrine is Observed Samples were drawn at 30 minutes pre-dose and at 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 25, 30, 40, 50, 60, 70, 80, 90, 120 minutes, 4, 6, 8, 12, 18, and 24 hours post-dose. Pharmacokinetic (PK) blood samples will be collected starting 30 minutes before dose and until 24 hours after dose. Plasma will be isolated for analyzing the concentrations of Albuterol and Epinephrine. t\[max\] will be obtained directly from the plot of PK curve when the maximum concentration is observed.
t[1/2], Terminal Elimination Half-life of Albuterol or Epinephrine Samples were drawn at 30 minutes pre-dose and at 1, 2, 3, 5, 7, 9, 12, 15, 18, 21, 25, 30, 40, 50, 60, 70, 80, 90, 120 minutes, 4, 6, 8, 12, 18, and 24 hours post-dose. Pharmacokinetic (PK) blood samples will be collected starting 30 minutes before dose and until 24 hours after dose. Plasma will be isolated for analyzing the concentrations of Albuterol and Epinephrine.
