Classes
Respiratory Long-Acting Beta-2 Agonists (LABA)
Administration
NOTE: Instruct patients that indacaterol is not intended to treat acute bronchospasm (see Precautions).
Dry powder inhalation (Arcapta Neohaler):
For oral inhalation use only. Instruct patients to NOT swallow the capsules.
Always use the Neohaler Inhaler to administer Arcapta capsules. This inhaler should not be used with any other medication. Do NOT use with a spacer.
To administer, use dry hands to remove a capsule from the blister pack immediately before use and place into the capsule chamber of the Neohaler inhaler. Click the inhaler closed. Do not place capsule into the mouthpiece. Then holding the inhaler upright, depress buttons fully one time to pierce capsule; a click will be heard. Have patient breathe out fully away from inhaler, place inhaler in the mouth with lips closed around the mouthpiece and buttons positioned to the left and right (not up and down), then breathe deeply, rapidly, and steadily in through the inhaler. A whirring sound should be heard; if no sound is heard, check the chamber as the capsule may be stuck. Gently tap the base of the device to loosen capsule if necessary. After inhalation, the patients should hold the breath as long as comfortable while removing inhaler from the mouth. Check the chamber to see if any powder remains in the capsule; repeat inhalation steps until no powder remains. Most patients can empty the capsule in one or two inhalations. After administration, open chamber and discard the empty capsule by tipping out.
Advise all patients that coughing after administration is not problematic; as long as the capsule is empty the full dose has been administered.
Occasionally the gelatin capsule might break into very small pieces which pass through the inhaler screen and reach the mouth. Accidental inhalation or ingestion of these pieces is harmless. Piercing capsule more than once increases risk of shattering capsule.
Do not wash inhaler; keep it dry. Although cleaning is not necessary, if desired, a clean, dry lint-free cloth or soft brush may be used to wipe out the inhaler.
Use the new inhaler provided with each new prescription.
To avoid the spread of infection, do not share inhaler device.

Description
Inhaled long-acting beta-2 adrenergic agonist (LABA); given once-daily
Used for the maintenance treatment of COPD in adults
Not indicated for the relief of acute bronchospasm or for the treatment of asthma
Dosage And Indications
75 mcg (contents of 1 capsule) via oral inhalation once daily at the same time every day is the recommended and max dose. Not indicated to treat acute exacerbations of COPD and should not be used for the relief of acute bronchospasm; use a short-acting beta-2 agonist (SABA) for rescue therapy. Indacaterol significantly improves exacerbation rates, breathlessness, and health status in patients with COPD. According to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines for COPD, long-acting beta-agonists (LABAs) may be used as initial monotherapy in patients in Groups A and B. In Group C patients, long-acting muscarinic antagonists (LAMAs) are preferred as initial therapy over LABAs due to effectiveness in preventing exacerbations. In Group D patients, LABAs are used as initial therapy in combination with inhaled corticosteroids (ICS) or LAMAs. At follow-up, if the patient is still experiencing dyspnea, consider switching inhaler device and investigate for other causes of dyspnea. If the patient has exacerbations, consider triple therapy with a LAMA, a LABA, and ICS.
Dosing Considerations
No dosage adjustments are needed in patients with mild to moderate hepatic impairment. Indacaterol has not been studied in patients with severe hepatic impairment; specific guidelines for dose adjustment are not available. As this drug undergoes hepatic metabolism, drug accumulation may be possible in patients with severe impairment.
Renal ImpairmentNo dosage adjustments are needed.
Drug Interactions
Acebutolol: (Moderate) Beta-blockers will block the pulmonary effects of inhaled beta-agonists, and in some cases may exacerbate bronchospasm in patients with reactive airways. Beta-agonists can sometimes increase heart rate or have other cardiovascular effects, particularly when used in high doses or if hypokalemia is present. Use of a beta-1-selective (cardioselective) beta blocker is recommended whenever possible when this combination of drugs must be used together. Monitor the patient's lung and cardiovascular status closely. Beta-agonists and beta-blockers are pharmacologic opposites and will counteract each other to some extent when given concomitantly, especially when non-cardioselective beta blockers are used.

Aclidinium; Formoterol: (Major) Formoterol should not be used in conjunction with other medications containing a long-acting beta-2 agonist for any reason, as overdose may result. Coadministration can result in overdosage. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. Acute symptoms should be treated with inhaled short-acting beta-2 agonists (SABA) such as albuterol. SABAs should not be used on a regular basis (e.g., 4 times a day) while taking formoterol. Increasing SABA use is a sign of deteriorating disease for which prompt medical attention is required. Prompt re-evaluation of the patient and their COPD treatment regimen should occur if formoterol no longer controls symptoms of bronchoconstriction, the patient's SABA rescue becomes less effective, or the patient requires more SABA rescue doses than usual. Use formoterol and drugs known to prolong the QTc interval together with extreme caution; this combination may increase the risk of cardiovascular effects and ventricular arrhythmias; this includes combination with other beta-agonists.

Itraconazole: (Major) Although no dosage adjustment of the 75 mcg/day indacaterol dose is needed, avoid use if possible. Consider alternatives. By inhibiting CYP3A4 and P-gp, itraconazole inhibits indacaterol metabolism. In drug interaction studies, coadministration of indacaterol inhalation powder 300 mcg (single dose) with another systemic azole antifungal with similar CYP3A4/P-gp activity caused a 1.9-fold increase in indacaterol exposure (AUC), and a 1.3-fold increase in indacaterol maximal concentration (Cmax). This may result in indacaterol side effects like tremor, nervousness, or a fast, irregular heart rate. Itraconazole has been associated with prolongation of the QT interval. Drugs with a possible risk for QT prolongation and torsade de pointes (TdP) that should be used cautiously and with close monitoring with itraconazole include the beta-agonists. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses and/or when associated with hypokalemia.
Ketoconazole: (Moderate) Monitor for beta-agonist side effects like tremor, nervousness, or fast, irregular heart rate, if indacaterol is coadministered with ketoconazole. Concurrent use may increase indacaterol exposure, although such increases in indacaterol exposure are unlikely to require any dose adjustment. Indacaterol is a CYP3A4 and P-gp substrate; ketoconazole is a strong CYP3A4 and P-gp inhibitor. In drug interaction studies, coadministration with ketoconazole caused an approximately 2-fold increase in indacaterol exposure.
Labetalol: (Moderate) Beta-blockers will block the pulmonary effects of inhaled beta-agonists, and in some cases may exacerbate bronchospasm in patients with reactive airways. Beta-agonists can sometimes increase heart rate or have other cardiovascular effects, particularly when used in high doses or if hypokalemia is present. Use of a beta-1-selective (cardioselective) beta blocker is recommended whenever possible when this combination of drugs must be used together. Monitor the patient's lung and cardiovascular status closely. Beta-agonists and beta-blockers are pharmacologic opposites and will counteract each other to some extent when given concomitantly, especially when non-cardioselective beta blockers are used.
Levobunolol: (Moderate) Beta-blockers will block the pulmonary effects of inhaled beta-agonists, and in some cases may exacerbate bronchospasm in patients with reactive airways. Beta-agonists can sometimes increase heart rate or have other cardiovascular effects, particularly when used in high doses or if hypokalemia is present. Use of a beta-1-selective (cardioselective) beta blocker is recommended whenever possible when this combination of drugs must be used together. Monitor the patient's lung and cardiovascular status closely. Beta-agonists and beta-blockers are pharmacologic opposites and will counteract each other to some extent when given concomitantly, especially when non-cardioselective beta blockers are used.
Levoketoconazole: (Moderate) Monitor for beta-agonist side effects like tremor, nervousness, or fast, irregular heart rate, if indacaterol is coadministered with ketoconazole. Concurrent use may increase indacaterol exposure, although such increases in indacaterol exposure are unlikely to require any dose adjustment. Indacaterol is a CYP3A4 and P-gp substrate; ketoconazole is a strong CYP3A4 and P-gp inhibitor. In drug interaction studies, coadministration with ketoconazole caused an approximately 2-fold increase in indacaterol exposure.
Levothyroxine: (Moderate) Monitor blood pressure and heart rate during concomitant beta-agonist and thyroid hormone use. Concurrent use may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease.
Levothyroxine; Liothyronine (Porcine): (Moderate) Monitor blood pressure and heart rate during concomitant beta-agonist and thyroid hormone use. Concurrent use may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease.
Levothyroxine; Liothyronine (Synthetic): (Moderate) Monitor blood pressure and heart rate during concomitant beta-agonist and thyroid hormone use.

Lonafarnib: (Moderate) Monitor for beta-agonist side effects like tremor, nervousness, or fast, irregular heart rate, if indacaterol is coadministered with lonafarnib. Concurrent use may increase indacaterol exposure, although such increases in indacaterol exposure are unlikely to require any dose adjustment. Indacaterol is a CYP3A4 and P-gp substrate; lonafarnib is a P-gp and strong CYP3A4 inhibitor. In drug interaction studies, coadministration of indacaterol inhalation powder 300 mcg (single dose) with another dual strong CYP3A4 and P-gp inhibitor caused an approximately 2-fold increase in indacaterol exposure.
Loop diuretics: (Moderate) Use beta-agonists and loop diuretics with caution due to risk for ECG changes and/or hypokalemia. The ECG changes and/or hypokalemia that may result from administration of loop diuretics can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded.
Lopinavir; Ritonavir: (Moderate) Although no dosage adjustment of the 75 mcg indacaterol daily dose is needed, use caution if indacaterol and ritonavir are used concurrently. Monitor the patient clinically for beta-agonist side effects like tremor, nervousness, or fast, irregular heart rate. In addition, both ritonavir and long-acting beta agonists (LABAs) are associated with QT prolongation; concomitant use may increase the risk of QT prolongation. By inhibiting CYP3A4, CYP2D6, and P-glycoprotein, ritonavir reduces indacaterol metabolism. In drug interaction studies, coadministration of indacaterol 300 mcg (single dose) with ritonavir (300 mg twice daily for 7.5 days) resulted in a 1.7-fold increase in indacaterol exposure (AUC) whereas indacaterol maximal concentration (Cmax) was unaffected.
Loratadine; Pseudoephedrine: (Moderate) Administer sympathomimetics with caution with beta-agonists such as indacaterol. The cardiovascular effects of beta-2 agonists may be potentiated by concomitant use. Monitor the patient for tremors, nervousness, increased heart rate, or other additive side effects.
Lumacaftor; Ivacaftor: (Moderate) Lumacaftor; ivacaftor may alter the systemic exposure of indacaterol; use together with caution. Indacaterol is a substrate of CYP3A4 and the P-glycoprotein (P-gp) drug transporter. Lumacaftor is a strong CYP3A inducer; in vitro data suggests lumacaftor; ivacaftor may also induce and/or inhibit P-gp. While the induction of indacaterol through the CYP3A pathway may lead to decreased plasma concentrations of indacaterol, the net effect of lumacaftor; ivacaftor on P-gp transport is not clear.
Methacholine: (Major) Discontinue use of indacaterol 48 hours before a methacholine challenge test. Beta-agonists inhibit the airway response to methacholine.

Racepinephrine: (Moderate) Administer sympathomimetics with caution with beta-agonists such as indacaterol. The cardiovascular effects of beta-2 agonists may be potentiated by concomitant use. Monitor the patient for tremors, nervousness, increased heart rate, or other additive side effects.
Rasagiline: (Moderate) The concomitant use of rasagiline and sympathomimetic agents was not allowed in clinical studies; therefore, caution is advised during concurrent use of rasagiline and respiratory adrenergic agents (e.g., the beta-agonists). Although sympathomimetic agents are contraindicated for use with traditional non-selective monoamine oxidase inhibitors (MAOIs), hypertensive reactions generally are not expected to occur during concurrent use with rasagiline because of the selective monoamine oxidase-B (MAO-B) inhibition of rasagiline at manufacturer recommended doses. However, the cardiovascular effects of beta-2 agonists may be potentiated by concomitant use of MAOIs. At least one case of hypertension occurred in a patient with previous episodes of high blood pressure who was receiving albuterol and selegiline, a selective MAOI related to rasagiline, concurrently. Close observation for such effects is prudent, particularly if beta-2 agonists are administered during or within 2 weeks of use of an MAOI.
Ribociclib: (Moderate) Due to a possible risk for QT prolongation, ribociclib and long-acting beta-agonists should be used together cautiously. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses, when associated with hypokalemia, or when used with other drugs known to prolong the QT interval like ribociclib. This risk may be more clinically significant with long-acting beta-agonists such as indacaterol as compared to short-acting beta-agonists.
Ribociclib; Letrozole: (Moderate) Due to a possible risk for QT prolongation, ribociclib and long-acting beta-agonists should be used together cautiously. Beta-agonists may be associated with adverse cardiovascular effects including QT interval prolongation, usually at higher doses, when associated with hypokalemia, or when used with other drugs known to prolong the QT interval like ribociclib. This risk may be more clinically significant with long-acting beta-agonists such as indacaterol as compared to short-acting beta-agonists.
Ritonavir: (Moderate) Although no dosage adjustment of the 75 mcg indacaterol daily dose is needed, use caution if indacaterol and ritonavir are used concurrently. Monitor the patient clinically for beta-agonist side effects like tremor, nervousness, or fast, irregular heart rate. In addition, both ritonavir and long-acting beta agonists (LABAs) are associated with QT prolongation; concomitant use may increase the risk of QT prolongation. By inhibiting CYP3A4, CYP2D6, and P-glycoprotein, ritonavir reduces indacaterol metabolism. In drug interaction studies, coadministration of indacaterol 300 mcg (single dose) with ritonavir (300 mg twice daily for 7.5 days) resulted in a 1.7-fold increase in indacaterol exposure (AUC) whereas indacaterol maximal concentration (Cmax) was unaffected.
Salmeterol: (Major) Indacaterol should not be used in conjunction with other medications containing a long-acting beta-2 agonist, such as salmeterol for any reason, as overdose may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. Acute symptoms should be treated with an inhaled short-acting beta-2 agonist (SABA) such as albuterol. SABAs should not be used on a regular basis (e.g., 4 times a day) while taking indacaterol. Increasing SABA use is a sign of deteriorating disease for which prompt medical attention is required. Prompt re-evaluation of the patient and their COPD treatment regimen should occur if indacaterol no longer controls symptoms of bronchoconstriction, the patient's SABA rescue becomes less effective, or the patient requires more SABA rescue doses than usual.
Serdexmethylphenidate; Dexmethylphenidate: (Moderate) Administer sympathomimetics with caution with beta-agonists such as indacaterol. The cardiovascular effects of beta-2 agonists may be potentiated by concomitant use. Monitor the patient for tremors, nervousness, increased heart rate, or other additive side effects.
Sympathomimetics: (Moderate) Administer sympathomimetics with caution with beta-agonists such as indacaterol. The cardiovascular effects of beta-2 agonists may be potentiated by concomitant use. Monitor the patient for tremors, nervousness, increased heart rate, or other additive side effects.
Theophylline, Aminophylline: (Moderate) Beta-agonists are commonly used in conjunction with aminophylline or theophylline therapy. Concomitant use can cause additive CNS stimulation; some patients may experience tremor or nervousness with combined use. More serious effects are rare, but may result in additive cardiovascular effects such as increased blood pressure and heart rate. Methylxanthine derivatives, ((e.g., theophylline and aminophylline) may rarely aggravate the hypokalemic effect seen with beta-agonists. Consider checking potassium levels if clinically indicated. (Moderate) Beta-agonists are commonly used in conjunction with aminophylline or theophylline therapy. Concomitant use can cause additive CNS stimulation; some patients may experience tremor or nervousness with combined use. More serious effects are rare, but may result in additive cardiovascular effects such as increased blood pressure and heart rate. Methylxanthine derivatives, (e.g., theophylline, aminophylline) may rarely aggravate the hypokalemic effect seen with beta-agonists. Consider checking potassium levels if clinically indicated.
Thiazide diuretics: (Minor) Hypokalemia associated with thiazide diuretics can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is unknown, use caution when coadministering beta-agonists with thiazide diuretics and monitor serum potassium as clinically indicated.
Thyroid hormones: (Moderate) Monitor blood pressure and heart rate during concomitant beta-agonist and thyroid hormone use. Concurrent use may increase the effects of sympathomimetics or thyroid hormone. Thyroid hormones may increase the risk of coronary insufficiency when sympathomimetic agents are administered to patients with coronary artery disease.
Timolol: (Moderate) Beta-blockers will block the pulmonary effects of inhaled beta-agonists, and in some cases may exacerbate bronchospasm in patients with reactive airways. Beta-agonists can sometimes increase heart rate or have other cardiovascular effects, particularly when used in high doses or if hypokalemia is present. Use of a beta-1-selective (cardioselective) beta blocker is recommended whenever possible when this combination of drugs must be used together. Monitor the patient's lung and cardiovascular status closely. Beta-agonists and beta-blockers are pharmacologic opposites and will counteract each other to some extent when given concomitantly, especially when non-cardioselective beta blockers are used.
Tiotropium; Olodaterol: (Major) Indacaterol should not be used in conjunction with other medications containing a long-acting beta-2 agonist, such as olodaterol, for any reason, as overdose may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. Acute symptoms should be treated with an inhaled short-acting beta-2 agonist (SABA) such as albuterol. SABAs should not be used on a regular basis (e.g., 4 times a day) while taking indacaterol. Increasing SABA use is a sign of deteriorating disease for which prompt medical attention is required. Prompt re-evaluation of the patient and their COPD treatment regimen should occur if indacaterol no longer controls symptoms of bronchoconstriction, the patient's SABA rescue becomes less effective, or the patient requires more SABA rescue doses than usual.
Torsemide: (Moderate) Use beta-agonists and loop diuretics with caution due to risk for ECG changes and/or hypokalemia. The ECG changes and/or hypokalemia that may result from administration of loop diuretics can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded.
Trandolapril; Verapamil: (Minor) Although no dosage adjustment of the 75 mcg indacaterol daily dose is needed, use caution if indacaterol and verapamil are used concurrently. By inhibiting CYP3A4 and P-gp, verapamil alters indacaterol metabolism. In drug interaction studies, coadministration of indacaterol 300 mcg (single dose) with verapamil (80 mcg 3 times daily for 4 days) resulted in a 2-fold increase in indacaterol AUC (0-24), and 1.5-fold increase in indacaterol Cmax.
Tranylcypromine: (Moderate) Use beta-agonists with caution in patients receiving concomitant monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping treatment with MAOIs because the action of beta-agonists on the cardiovascular system may be potentiated.
Tucatinib: (Moderate) Monitor for indacaterol-related adverse effects, such as headache, nervousness, tremor, or cardiovascular effects, during coadministration with tucatinib. Concurrent use may increase plasma concentrations of indacaterol. Indacaterol is a CYP3A4 and P-glycoprotein (P-gp) substrate; tucatinib is a strong CYP3A4 inhibitor and P-gp inhibitor. Coadministration with other dual inhibitors of CYP3A4 and P-gp has increased exposure of indacaterol from 1.4- to 1.9- fold.
Umeclidinium; Vilanterol: (Major) Indacaterol should not be used with vilanterol for any reason, as sympathomimetic overdose and additive anticholinergic effects may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. Acute symptoms should be treated with an inhaled short-acting beta-2 agonist (SABA) such as albuterol. SABAs should not be used on a regular basis (e.g., 4 times a day) while taking indacaterol. Increasing SABA use is a sign of deteriorating disease for which prompt medical attention is required. Prompt re-evaluation of the patient and their COPD treatment regimen should occur if indacaterol no longer controls symptoms of bronchoconstriction, the patient's SABA rescue becomes less effective, or the patient requires more SABA rescue doses than usual.
Verapamil: (Minor) Although no dosage adjustment of the 75 mcg indacaterol daily dose is needed, use caution if indacaterol and verapamil are used concurrently. By inhibiting CYP3A4 and P-gp, verapamil alters indacaterol metabolism. In drug interaction studies, coadministration of indacaterol 300 mcg (single dose) with verapamil (80 mcg 3 times daily for 4 days) resulted in a 2-fold increase in indacaterol AUC (0-24), and 1.5-fold increase in indacaterol Cmax.

Mechanism Of Action
Indacaterol is an agonist at beta-2 receptors. These receptors are present in large numbers in the lungs and are located on bronchiolar smooth muscle. Stimulation of beta-2 receptors in the lung causes relaxation of bronchial smooth muscle, which produces bronchodilation and a resultant increase in bronchial airflow. These effects are believed to be mediated, in part, by increased activity of adenyl cyclase, an intracellular enzyme responsible for the formation of cyclic-3',5'-adenosine monophosphate (cAMP).
Indacaterol has more than a 24-fold greater agonist activity at beta-2 receptors (primarily in the lung) than at beta-1 receptors (primarily in the heart). However, 10% to 50% of the beta receptors in the heart are beta-2 receptors. Even highly selective beta-2 receptor agonists may have adverse cardiovascular effects, such as tachycardia, palpitations, and ischemia. Other common adverse effects due to activation of beta-receptors include skeletal muscle tremors and cramps, insomnia, decreases in serum potassium, and increases in blood glucose.
Pharmacokinetics
Indacaterol is administered by oral inhalation. Protein binding is approximately 94 to 96%. In pharmacokinetic study of orally administered radiolabeled drug, unchanged indacaterol was the single largest form of the drug in serum, approximately 1/3 of total drug-related AUC over 24 hours. A hydroxylated derivative was the most prominent metabolite in serum. Glucuronate and dealkylate products, among other metabolites, were also identified. CYP3A4 is concluded to be the predominant isoenzyme responsible for hydroxylation; CYP1A1, CYP2D6, and UGT1A1 enzymes are also involved in metabolism to a minor extent. Elimination appears to be multi-phasic with an average terminal half-life of 45.5 to 126 hours. Renal elimination accounts for approximately 2 to 6% of systemic clearance; following oral administration, 90% or more of the dose was recovered fecally.
Affected cytochrome P450 (CYP450) isoenzymes and drug transporters: CYP3A4, P-glycoprotein (P-gp)
Indacaterol is not likely to inhibit or induce the transport or metabolism of other drugs. CYP3A4 is the predominant isoenzyme responsible for the hydroxylation of indacaterol; indacaterol also has a low affinity for the efflux pump P-glycoprotein (P-gp). Drug interaction studies suggest potent and specific dual inhibitors of CYP3A4 and P-gp (e.g., ketoconazole, erythromycin, verapamil, ritonavir) may increase indacaterol exposure; however, this inhibition does not result in a need for dose adjustment of the usual therapeutic inhalation doses (75 mcg/day) of indacaterol.
Following inhalation by patients with moderate to severe COPD, a change in FEV-1 has been seen within 5 minutes of 150 mcg or 300 mcg dose administration. Indacterol exerts a similar effect to albuterol use, and a statistically greater effect to either salmeterol-fluticasone (p < 0.001) or placebo (p < 0.001) use, as measured by FEV-1 at 5-minutes post-dose. The median time to reach peak serum concentrations of indacaterol is approximately 15 minutes after single or repeated oral inhalational doses. Absolute bioavailability of the inhaled drug is 43—45%, from both pulmonary and intestinal absorption. Indacaterol serum concentrations increase with repeated once-daily administration. Steady-state concentrations are achieved within 12 to 15 days.
Pregnancy And Lactation
There are no adequate and well-controlled studies in pregnant women; indacaterol should only be used during pregnancy if the expected benefit to the patient outweighs the potential risk to the fetus. Animal studies have not shown evidence of teratogenic effects; however, use with caution in pregnancy since animal data are not always predictive of human response. Women should contact their physician if they become pregnant while taking indacaterol. It is known that improved maternal and perinatal outcomes are achieved with optimal control of asthma during pregnancy. Large studies of women with asthma have confirmed the lack of relationship between the use of inhaled beta-2 agonists and adverse maternal or fetal outcomes; however, fewer data are available for long-acting beta agonists (LABAs) such as indacaterol vs. short-acting beta agonists (SABAs). However, most inhaled beta-2 agonists are considered acceptable for use during pregnancy because of the low bioavailability and maternal serum levels after use. During pregnancy, the use of another LABA, such as salmeterol or formoterol, with which there is more experience during pregnancy may be preferable. The use of indacaterol during labor and obstetric delivery has not been studied. Because of the potential for beta agonist interference with uterine contractility, use of indacaterol during labor should be restricted to those patients in whom the benefits clearly outweigh the risks.
