This is a randomized, open label, single-center, single-dose, four-period crossover clinical study to assess the pharmacokinetic profile and safety of a budesonide inhalation solution (AQ001S) compared to a budesonide inhalation suspension (comparator) in healthy volunteers. Three (3) different AQ001S concentrations (i.e. 0.125 mg/2 mL, 0.250 mg/2mL and 0.500 mg/2 mL) will be compared to budesonide inhalation suspension 1.0 mg/2 ml.~Twenty (20) male and female healthy volunteers, from 18 to 60 years old, must complete the study. The study drug will be administered by nebulization.~The primary PK objective is to characterize the pharmacokinetic (PK) profile of AQ001S inhalation solution.~The primary safety objective is to assess the safety of AQ001S inhalation solution.
