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

Nebulization: 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 and do not mix with other medications in nebulizer.
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: [US Boxed Warning]: Long-acting beta2-agonists (LABAs) increase the risk of asthma-related deaths. Monotherapy with a LABA is contraindicated in the treatment of asthma. In a large, randomized, placebo-controlled US clinical trial (SMART 2006), salmeterol was associated with an increase in asthma-related deaths (when added to usual asthma therapy); risk is considered a class effect among all LABAs. Data are not available to determine if the addition of an inhaled corticosteroid lessens this increased risk of death associated with LABA use; however, current guidelines recommend the use of an inhaled corticosteroid before adding a LABA (GINA 2015; NIH/NHLBI 2007). LABAs should not be used for acute bronchospasm. In a more recent multicenter, randomized, double-blinded trial, the use of salmeterol and an inhaled corticosteroid (ie, fluticasone) combined in a single inhaler in a large number of children, adolescent, and adult patients with persistent asthma (non-life threatening and stable) did not increase the risk of serious asthma-related events compared with fluticasone alone; in addition, patients receiving fluticasone/salmeterol had fewer severe asthma exacerbations compared with patients receiving fluticasone alone (Peters 2016; Stempel 2016a; Stempel 2016b). Safety and efficacy of arformoterol in patients with asthma have not been established.
• 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; 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. Beta2-agonists may also increase risk of arrhythmias and prolong QTc interval.
• COPD: Appropriate use: Do not use for acute episodes of COPD. Do not initiate in patients with significantly worsening or acutely deteriorating COPD. Data are not available to determine if LABA use increases the risk of death in patients with COPD.
• Diabetes: Use with caution in patients with diabetes mellitus. Beta2-agonists may increase serum glucose; the effect is usually transient.
• Hepatic impairment: Use with caution in patients with hepatic impairment; systemic clearance prolonged in hepatic dysfunction.
• Hyperthyroidism: Use with caution in patients with hyperthyroidism; may stimulate thyroid activity.
• Hypokalemia: Use with caution in patients with hypokalemia; beta2-agonists may decrease serum potassium.
• Seizure disorders: Use with caution in patients with seizure disorders; beta2-agonists may result in CNS stimulation/excitation.
• Pediatric: Arfomoterol is approved for COPD, which is a disease that does not occur in the pediatric population. Safety and efficacy have not been established in children.
• Patient information: Patients using inhaled, short-acting beta2-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 beta2-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 beta2-agonist inhalers; may be marker of a deteriorating COPD condition.
Pregnancy Risk Factor
Adverse events were observed in some animal reproduction studies. Beta-agonists may interfere with uterine contractility if administered during labor.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience back pain, diarrhea, or rhinitis. Have patient report immediately to signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of low potassium (muscle pain or weakness, muscle cramps, or an abnormal heartbeat), angina, tachycardia, severe anxiety, severe dizziness, passing out, chills, pharyngitis, swelling of arm or leg, severe headache, severe nausea, vomiting, difficulty speaking, signs of breathing problems (shortness of breath, wheezing, coughing, or breathing gets worse) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
