Primary outcomePrimary: Baseline Concentration (C0) of Total Epinephrine — 2.6; 4.3 pg/mL
Summary
This study examines the pharmacokinetic profile of Armstrong's proposed Epinephrine Inhalation Aerosol USP, an HFA-MDI (E004), using a stable isotope deuterium-labeled epinephrine (epinephrine-d3) to differentiate the administered drug from the endogenous epinephrine, in healthy male and female adult volunteers. The current study is designed for a more thorough evaluation of the E004 Pharmacokinetics. Safety of E004 will also be evaluated, under augmented dose conditions.
