Outcome Measures

Primary Outcome Measures :
  1. Safety variables (ECG, adverse events, blood pressure, pulse, body temp, safety lab), lung function and physical examination [ Time Frame: Frequent sampling occasions during study days ]

Secondary Outcome Measures :
  1. Pharmacokinetics - Maximum plasma concentration (Cmax), time to Cmax (tmax), area under the plasma concentration-time curve from zero to the time of the last measurable concentration [AUC(0-t)] and from zero to infinity (AUC) [ Time Frame: Frequent sampling occasions during study days ]
  2. Add'l pharmacokinetics - Terminal rate constant (λz); terminal half-life (t½λz), Apparent plasma clearance (CL/F), apparent volume of distribution during terminal phase (Vz/F), mean residence time (MRT). [ Time Frame: Frequent sampling occasions during study days ]
  3. Pharmacodynamics - Plasma cortisol concentrations [ Time Frame: Frequent sampling occasions during study days ]
