  Purpose

To compare the effects of formoterol alone (Oxis® TurbuhalerÒ) and the fixed combination of formoterol and budesonide (Symbicort® TurbuhalerÒ) on airway responsiveness as a marker of inflammation, induced by repeated low-dose allergen challenge in allergic patients with mild asthma

Criteria

Inclusion Criteria:

  • A diagnosed history of asthma for at least 6 months
  • Mild and stable asthma, only using β2-agonists as needed for the last 4 weeks.
  • FEV1 >70% of predicted normal value (post-bronchodilator value).
  • Skin prick test positive to pollen, animal dander or house dust mite.

Exclusion Criteria:

  • Any significant respiratory disease, other than asthma.
  • Upper or lower respiratory tract infection within 4 weeks before inclusion.
  • Use of:

    1. inhaled glucocorticosteroid treatment for the last 8 weeks prior to inclusion or ever used oral glucocorticoid treatment for asthma.
    2. inhaled long-acting or oral b2-agonists, anticholinergic bronchodilators, cromones, antihistamines, theophyllines and anti-leukotrienes within 2 weeks of screening.
    3. regular NSAIDs
