Xopenex is used to treat or prevent bronchospasm in adults and children 6 years of age and older with asthma, as well as in patients with COPD and other reversible obstructive airway diseases. It is typically used as a rescue medication for acute symptoms.
Xopenex contains levalbuterol, which is the active (R)-enantiomer of albuterol. It works by stimulating beta-2 adrenergic receptors in the bronchial smooth muscle, causing relaxation of the airway muscles and widening of the air passages, which results in easier breathing.
Xopenex is a rescue inhaler and should not be used as a substitute for long-term control medications. Common side effects may include tremor, nervousness, headache, and tachycardia. Patients with heart conditions, diabetes, or seizures should use this medication with caution. Always follow prescribed dosing instructions and seek medical attention if symptoms worsen.
