Asthma Inflammation Extends Into Even the Smallest Airways1
- The small (<2 mm)3 airways are a primary site of asthma inflammation1,2
- Most inhaled corticosteroids (ICSs) aren’t formulated to get there
- As a result, small-airway inflammation is typically uncontrolled1
For Your Asthma Patient, Uncontrolled Small-Airway Inflammation Could Mean:
- Persistent symptoms1
- Increased asthma exacerbations1
- Small-airway anatomic changes, which can potentially lead to irreversible lung damage1
QVAR®: The Solution for Small-Airway Inflammation
Because Only QVAR Is a Small-Particle, Extra-Fine Aerosol Solution4
- The small particle size of QVAR (MMAD of 1.1 µm) penetrates more effectively into the small
airways than large-particle suspension formulations5
- QVAR delivers a greater mass of small particles to the peripheral lung6
- QVAR achieves high lung deposition of up to 58%*
- - Compared with 12 to 13% for fluticasone CFC1,5,7
- - Minimizes deposition in the mouth and throat5
- - Distributes evenly throughout the entire lung5
QVAR’s Deposition Is Consistent Even When Inhaler Technique Is Poor7
QVAR’s Anti-inflammatory Treatment Reaches the Entire Lung5
