Reversible obstructive airway disease
General Information
Xopenex is approved for the treatment or prevention of
bronchospasm in adults and children ages six years and older, who
suffer from reversible obstructive airway disease, such as asthma.
Xopenex has been approved since 1999 for use in adults and children
ages 12 and over. The pediatric indication was extended in February
2002. The inhaled solution is to be administered three times daily,
using a nebulizer system.
The American Lung Association estimates that 26 million
Americans have been diagnosed with asthma, the most common
reversible obstructive airway disease. Of these, 8.6 million are
under the age of 18.
Clinical Results
The approval of Xopenex is supported by one of the largest
pediatric asthma studies ever conducted with a beta-agonist.
Double-blind, placebo-controlled trials involving 338 subjects were
designed to modify the approved adult and adolescent dosages for
safe and effective use in children. Both doses of Xopenex tested in
subjects ages six to 11 years old were clinically comparable to
larger doses of a competitive treatment, for onset of effectiveness
and duration of effect.
Prior to it's original approval date, the safety and
efficacy of Xopenex was evaluated in a double-blind,
placebo-controlled study in adults and adolescents with asthma. On
both the first and last days of the study, Xorenex provided
subjects with equivalent or superior relief compared to larger
doses of a competitive treatment.
Side Effects
Adverse events associated with the use of Xopenex may include
(but are not limited to) the following:
- Flu syndrome
- Increased heart rate
- Nervousness
- Tremor
Mechanism of Action
Xopenex (levalbuterol HCl) inhalation solution binds to human
beta-adrenergic receptors on the smooth muscles of all airways.
This relaxes the airways, which protects against bronchoconstrictor
challenges.
