Arformoterol, the (R,R)-enantiomer of the racemic formoterol, is a long-acting beta2-agonist that relaxes bronchial smooth muscle by selective action on beta2-receptors with little effect on cardiovascular system.
A portion of inhaled dose is absorbed into systemic circulation
Hepatic via direct glucuronidation and secondarily via O-demethylation; CYP2D6 and CYP2C19 (to a lesser extent) involved in O-demethylation
Onset of Action
7-20 minutes; Peak effect: 1-3 hours
Time to Peak
52% to 65%
Special Populations: Hepatic Function Impairment
The systemic exposure (Cmax and AUC) to arformoterol increased 1.3- to 2.4-fold in subjects with hepatic impairment.
Use: Labeled Indications
Chronic obstructive pulmonary disease: Long-term maintenance treatment of bronchoconstriction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema
Hypersensitivity to arformoterol, racemic formoterol, or to any component of the formulation; monotherapy (without use of a concomitant inhaled corticosteroid) in the treatment of asthma.
Documentation of allergenic cross-reactivity for sympathomimetics is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Chronic obstructive pulmonary disease: Nebulization solution: 15 mcg twice daily; maximum: 30 mcg/day.
Refer to adult dosing.
Oral inhalation: Nebulization solution: Remove each vial from individually sealed foil pouch immediately before use. Use with standard jet nebulizer connected to an air compressor; administer with mouthpiece or face mask. Administer vial undiluted; compatibility with other medications (eg, budesonide, ipratropium) in nebulizer has been reported (Burchett 2010; Kamin 2014); also refer to institution-specific policies.
Prior to dispensing, store in protective foil pouch under refrigeration at 2°C to 8°C (36°F to 46°F). Protect from light and excessive heat. After dispensing, unopened foil pouches may be stored at 20°C to 25°C (68°F to 77°F) for up to 6 weeks. Only remove vial from foil pouch immediately before use.

Concerns related to adverse effects:
• Asthma-related deaths: Monotherapy with a long-acting beta-2 agonist (LABA) is contraindicated in the treatment of asthma. The use of LABAs as monotherapy has been associated with an increased risk of severe exacerbations and asthma-related deaths (SMART [Nelson 2006]; Walters 2007); additional data from other clinical trials suggest risk of asthma-related hospitalization may also be increased with LABA monotherapy in pediatric and adolescent patients. However, data from large, randomized, double-blind controlled trials do not show a significant increase in risk of serious asthma-related events (including hospitalizations, intubations, and death) in adults, adolescents, and pediatric patients (4 to 11 years of age) when fixed-dose LABAs are used with inhaled corticosteroids combined in a single inhaler compared with inhaled corticosteroid monotherapy (FDA 2017). Current guidelines recommend the use of an as-needed, low-dose inhaled corticosteroid with formoterol for patients with infrequent symptoms (GINA 2020). Arformoterol is not indicated for the treatment of asthma. Available data do not suggest an increased risk of death with use of LABA in patients with chronic obstructive pulmonary disease (COPD).
• Bronchospasm: Paradoxical bronchospasm that may be life-threatening may occur with use of inhaled bronchodilating agents; this reaction should be distinguished from inadequate response. Discontinue immediately if paradoxical bronchospasm occurs and institute alternative therapy.
• Hypersensitivity reactions: Immediate hypersensitivity reactions (anaphylaxis, urticaria, angioedema, rash, bronchospasm) have been reported.
• Serious effects/fatalities: Do not exceed recommended dose or frequency or use with other medications containing LABAs; serious adverse events, including fatalities, have been associated with excessive use of inhaled sympathomimetics.
• Cardiovascular disease: Use with caution in patients with cardiovascular disease (eg, arrhythmia, hypertension, HF); beta-agonists may cause elevation in blood pressure, heart rate and result in CNS stimulation/excitation. Beta-2 agonists have been reported to produce ECG changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression.
• COPD: Appropriate use: Do not use for acute episodes of COPD. Do not initiate in patients with significantly worsening or acutely deteriorating COPD. Available data do not suggest an increased risk of death with use of LABA in patients with COPD.
• Diabetes: Use with caution in patients with diabetes mellitus. Beta-2 agonists may increase serum glucose and aggravate preexisting diabetes mellitus and ketoacidosis.
• Hepatic impairment: Use with caution in patients with hepatic impairment; systemic exposure is increased.
• Hyperthyroidism: Use with caution in patients with hyperthyroidism; may stimulate thyroid activity.
• Hypokalemia: Use with caution in patients with hypokalemia; beta-2 agonists may decrease serum potassium (transient).
• Seizures: Use with caution in patients with seizure disorders; beta-2 agonists may result in CNS stimulation/excitation.
• Pediatric: LABAs, when used as monotherapy, may increase the risk of asthma-related hospitalization in pediatric and adolescent patients. When LABAs are used in a fixed-dose combination with inhaled corticosteroids, data from large clinical trials in adolescents do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared to inhaled corticosteroids alone.
• Patient information: Patients using inhaled, short-acting beta-2 agonists (eg, albuterol) should be instructed to discontinue routine use of these medications prior to beginning treatment; short-acting agents should be reserved for symptomatic relief of acute symptoms. Patients must be instructed to seek medical attention in cases where acute symptoms are not relieved or a previous level of response is diminished. The need to increase frequency of use of short-acting beta-2 agonists may indicate deterioration of COPD, and medical evaluation must not be delayed.
• Tolerance/Tachyphylaxis: Tolerance to the bronchodilator effect, measured by FEV1, has been observed in studies.
FEV1, peak flow, and/or other pulmonary function tests; blood pressure, heart rate; CNS stimulation; serum glucose, serum potassium. Monitor for increased use of short-acting beta 2-agonist inhalers; may be marker of a deteriorating COPD condition, hypersensitivity reactions, decreased bronchodilator response (tachyphylaxis).
Beta-agonists may interfere with uterine contractility if administered during labor.
