formoterol + levalbuterol

**Formoterol + levalbuterol** denotes co-administration of two inhaled selective beta-2 adrenergic receptor agonist bronchodilators rather than a recognized single fixed-dose drug product. Formoterol is a long-acting beta-2 agonist used for maintenance bronchodilation, while levalbuterol is the active R-enantiomer of albuterol and a short-acting beta-2 agonist used for rapid relief or prevention of bronchospasm. Both relax airway smooth muscle through beta-2 receptor activation; concurrent use can produce additive sympathomimetic effects, including tachycardia, blood-pressure elevation, tremor, and arrhythmia risk. Levalbuterol inhalation products are indicated for bronchospasm associated with reversible obstructive airway disease.
