Study Description

Brief summary:

This study is to compare the systemic exposure of budesonide delivered by the combination inhaler (budesonide/albuterol sulfate pressurized inhalation suspension [BDA metered dose inhaler {BDA MDI}]) with Pulmicort Flexhaler dry-powder inhaler (DPI).

  • Condition or Disease:Relative Bioavailability
  • Intervention/Treatment: Drug: BDA MDI 160/180 mcg
    Drug: Pulmicort Flexhaler 180 mcg
  • Phase: Phase 1

Detailed Description

This study will be an open-label, randomized, 2-way cross-over study in healthy adult male or female participants, performed at a single study center.Participants will receive single doses of BDA MDI or Pulmicort Flexhaler on 2 occasions, under fasted conditions. There will be a minimum washout period of 3 days between each dose administration. A total of 66 participants will be randomized in this study to ensure that at least 62 participants are evaluable. The study will comprise of screening period of maximum 27 days; Two treatment periods during which participants will be resident from the day prior to administration of budesonide/albuterol sulfate pressurized inhalation suspension metered dose inhaler (BDA MDI) or Pulmicort Flexhaler (Day -1) until at least 24 hours after dosing. Participants will be discharged on the morning of Day 2; and a final follow-up visit within 5 to 7 days after the last administration of BDA MDI or Pulmicort Flexhaler.
