Brief Summary

Glucocorticosteroids recently have been shown to have non-genomic actions that are plasma membrane-mediated and do not require gene transcription and translation. One of these non-genomic effects is the inhibition of adrenergic agonist transport into airway vascular smooth muscle cells with an increase of adrenergic agonist concentrations at adrenergic receptor sites and enhance the physiological effects of endogenous adrenergic agonists (e.g. locally released norepinephrine from noradrenergic neurons) or exogenous adrenergic agonists (e.g. inhaled beta-adrenergic agonists).

Outcome Measures

Primary Outcomes (1)

  • Airway Blood Flow (Qaw)

    Qaw will be measured before and up to 6 hours after a single inhaled dose of 360ug, 720ug, and 1440ug budesonide or placebo from a DPI, using a double-blinded randomized design on different days.

    participants will be followed for 6 hours after budesonide dose

Secondary Outcomes (1)

  • Forced Expiratory Volume in 1 Second (FEV1)

    participant will be followed up to 6 hours after budesonide dose
