Systemic and local corticosteroid use may result in the following:

  • Candida albicans infection.
  • Immunosuppression, increased risk of infections.
  • Hypercorticism and adrenal suppression.
  • Reduction in bone mineral density.
  • Effects on growth.
  • Glaucoma, increased intraocular pressure and cataracts.
  • Bronchospasm.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The following table shows the adverse reactions that were reported in patients previously receiving bronchodilators and/or orally inhaled corticosteroids in two double-blind, placebo-controlled US clinical trials, in which 519 adult and pediatric patients age 4-78 years (279 males and 240 females) were treated with the AEROSPAN Inhalation Aerosol (80 mcg to 320 mcg twice daily for 12 weeks) or placebo. The mean duration of exposure was 76.7, 78.2, 80.5, and 69.4 days for AEROSPAN Inhalation Aerosol 80 mcg, 160 mcg, 320 mcg, and placebo, all dosed twice daily, respectively. The table includes all reactions that occurred at a rate of > 3% in any AEROSPAN Inhalation Aerosol group. In considering these data, the increased average duration of exposure for AEROSPAN Inhalation Aerosol patients should be taken into account, compared with placebo-treated patients.

Long-Term Clinical Trials

Two 52-week open label safety trials of AEROSPAN Inhalation Aerosol were conducted in 162 asthma patients 12 to 60 years of age and in 152 asthma patients 4 to 11 years of age. The adverse reaction profile exhibited in these trials was similar to that seen in the two 12-week studies.
