ASTHMA CONTROL*

Greater Lung Deposition With QVAR®

QVAR® is an inhaled corticosteroid (ICS) with a mean particle size of 1.1 µm—smaller than that of most other ICSs. This small particle size allows QVAR® to reach both the large and small airways of the lungs more effectively than larger-particle ICSs.1-3 To see how lung deposition with QVAR® compares with other inhaled asthma control medications, click the images below.

Particle size and lung deposition - comparison with Flovent® CFC
Particle size and lung deposition - comparison with Advair® CFC
  • QVAR® is evenly distributed throughout the large and small airways, achieving a lung deposition of up to 58%.2
  • Even patients with poor inhaler technique can achieve more than 30% lung deposition.2
  • About 50% of asthma patients use poor inhaler technique.2

Large-particle ICS and ICS/LABA combination products are less likely to reach and treat the small airways, where underlying chronic inflammation may persist.4-6

QVAR® (beclomethasone dipropionate HFA) Inhalation Aerosol is indicated in the maintenance treatment of asthma as prophylactic therapy in patients 5 years of age or older. QVAR® is also indicated for asthma patients who require systemic corticosteroid administration, where adding QVAR® may reduce or eliminate the need for systemic corticosteroids.

Important Safety Information

  • QVAR® is not a bronchodilator and is not indicated for relief of acute bronchospasm
  • Common side effects associated with the use of QVAR® and placebo in clinical trials include, but are not limited to, headache (12% and 9%, respectively) and pharyngitis (8% and 4%, respectively)
CAUTION: Adrenal insufficiency may occur when transferring patients from systemic steroids (see WARNINGS, Prescribing Information).
  • A reduction in growth velocity in growing children and teenagers may occur as a result of inadequate control of chronic diseases such as asthma or from use of corticosteroids for treatment

* The relationship of better lung deposition and particle size to clinical efficacy is unknown.
