Adult Patients

XOPENEX HFA^® (levalbuterol tartrate) Inhalation Aerosol
has been shown to deliver fast and consistent asthma relief and is well tolerated in adults.^1-3

*On Day 1, the median duration of effect was 3 to 4 hours, with a duration of effect in some patients of up to 6 hours.

Data from 2 double-blind, randomized, placebo- and active-controlled, multicenter, parallel-group, 8-week trials of patients aged ≥12 years (N=748) with moderate-to-severe asthma (FEV₁ was ≥45% to ≤75% predicted). Primary endpoint was peak percent change from visit predose in FEV₁ averaged over the double-blind period.

There was a significantly larger peak percent change in FEV₁ from visit predose with XOPENEX HFA^® (levalbuterol tartrate) relative to the placebo group averaged over the double-blind period (primary endpoint) (P<0.001)^2,3

Low incidence of β-mediated adverse events^2,3

Adverse event information concerning XOPENEX HFA^® (levalbuterol tartrate) Inhalation Aerosol in adults and adolescents is derived from two 8-week, multicenter, randomized, double-blind, active- and placebo-controlled trials in 748 adult and adolescent patients with asthma that compared XOPENEX HFA Inhalation Aerosol, a marketed albuterol HFA inhaler, and an HFA-134a placebo inhaler.

The most common adverse events in patients aged 12 years and older (occurring in ≥2% of patients receiving XOPENEX HFA at 90 mcg and more frequently than patients receiving placebo) were asthma, pharyngitis, rhinitis, pain, and dizziness¹

Important Safety Information & Indication

XOPENEX HFA is contraindicated in patients with a history of hypersensitivity to levalbuterol tartrate, racemic albuterol, or any component of the drug product.

Patients receiving the highest dose of XOPENEX HFA should be monitored closely for adverse effects, and the risk of such effects should be balanced against the potential for improved efficacy.

XOPENEX HFAand other β-agonists can cause paradoxical bronchospasm, which may be life threatening.

XOPENEX HFA like other β-adrenergic agonists, can produce clinically significant cardiovascular effects in some patients as measured by heart rate, blood pressure, and/or symptoms.

Potential drug interactions include: β-blockers, which can block the pulmonary effect of β-agonists and can cause severe bronchospasm in asthmatic patients; diuretics (non-potassium-sparing), whose ECG changes and/or hypokalemia side effects can worsen with administration of β-agonists; digoxin, where serum levels can decrease 16% to 22% with administration of β-agonists; monoamine oxidase inhibitors and tricyclic antidepressants, which can potentiate the action of albuterol on the vascular system.

If additional adrenergic drugs, including other short-acting sympathomimetic bronchodilators or epinephrine, are to be administered by any route, they should be used with caution to avoid deleterious cardiovascular effects.

Due to the cardiovascular side effects associated with β-agonists, caution is generally recommended for patients with cardiovascular disorders (especially coronary insufficiency, cardiac arrhythmias, and hypertension), diabetes, hyperthyroidism, or convulsive disorders.

In patients aged 4 to 11 years, the most common adverse events (occurring in ≥2% of patients receiving XOPENEX HFA at 90 mcg and more frequently than patients receiving placebo) were vomiting, accidental injury, pharyngitis, and bronchitis.

In patients 12 years and older, the most common adverse events (occurring in ≥2% of patients receiving XOPENEX HFA at 90 mcg and more frequently than patients receiving placebo) were asthma, pharyngitis, rhinitis, pain, and dizziness.
