Treatment of bronchospasm in patients with COPD,Long-term maintenance treatment of asthma
Treatment or prevention of bronchospasm in patients with reversible obstructive airway disease,Prevention of exercise-induced bronchospasm,Off-label: Acute hyperkalemia (via nebulization)
AEROLONE is not a recognized drug; no standard dosing available.
2.5 mg (0.5 m L of 0.5% solution) via nebulization every 4-6 hours as needed; or 1-2 inhalations (90 mcg/inhalation) from a metered-dose inhaler every 4-6 hours as needed.
Terminal elimination half-life is approximately 12-15 hours in adults; prolonged to 24-30 hours in severe renal impairment (Cr Cl <30 m L/min).
Terminal elimination half-life is 3.8-6.0 hours. In patients with asthma, the half-life is similar, but clinical effect duration is shorter due to rapid redistribution from the receptor site.
Primarily metabolized by CYP3A4 and to a lesser extent CYP2D6, with conjugation to inactive metabolites.
Primarily metabolized via sulfotransferase (SULT1A3) to inactive sulfate conjugate; minor hepatic metabolism by CYP450 enzymes.
Primarily renal excretion of unchanged drug (approximately 65%) and hepatic metabolism (35%), with metabolites excreted in urine and feces. Biliary/fecal elimination accounts for <10%.
Primarily renal: approximately 60-70% of the dose is excreted in urine as unchanged drug and metabolites (sulfate conjugate) within 24 hours. Fecal excretion accounts for less than 10%.
Approximately 88% bound, primarily to albumin and alpha-1-acid glycoprotein.
Approximately 52-65% bound to human serum albumin and alpha-1-acid glycoprotein.
3.5-5.0 L/kg, indicating extensive extravascular distribution and tissue binding.
Approximately 1.4-2.0 L/kg. This relatively large Vd indicates extensive distribution into tissues, including lung parenchyma.
Oral: 35-50% (first-pass metabolism); Inhalation: 15-30% (dependent on device and technique); Intravenous: 100%.
Inhaled: 10-20% of the dose reaches the lungs systemically; Oral: approximately 28-40% (due to first-pass metabolism to sulfate conjugate); Subcutaneous: nearly 100%.
No data; not applicable.
No dosage adjustment required for renal impairment.
No data; not applicable.
No specific guidelines; use with caution in severe hepatic impairment due to potential for increased systemic exposure.
No data; not applicable.
Nebulized: 0.05-0.15 mg/kg/dose (minimum 1.25 mg) every 4-6 hours as needed. MDI: 1-2 inhalations (90 mcg/inhalation) every 4-6 hours as needed. Maximum: 12 inhalations/day.
No data; not applicable.

Paradoxical bronchospasm may occur with excessive use,Cardiovascular effects: increased heart rate, hypertension, arrhythmias,Hypokalemia may occur with high doses,Immediate hypersensitivity reactions possible,Use caution in patients with cardiovascular disorders, hyperthyroidism, diabetes, or seizure disorders
Hypersensitivity to arformoterol or any component of the formulation
Hypersensitivity to albuterol or any component of the formulation
No significant food interactions. Avoid grapefruit juice as it may affect metabolism of the corticosteroid component.
No clinically significant food interactions. Caffeine may potentiate stimulant effects; avoid excessive caffeine intake.
No evidence of teratogenicity in animal studies at doses up to 10 mg/kg/day (approximately 120 times the maximum recommended human daily inhaled dose). In humans, no controlled studies exist; however, data from postmarketing reports do not suggest an increased risk of structural anomalies. First trimester: limited data preclude definitive risk assessment, but no pattern of major birth defects has emerged. Second and third trimesters: no known fetal harm from inhaled doses; however, potential for fetal adrenal suppression with prolonged high-dose systemic exposure.
FDA Pregnancy Category C. In first trimester, no increased risk of major congenital anomalies based on human data. Second and third trimesters: risk of maternal tachycardia, hyperglycemia; fetal tachycardia, hypoglycemia at birth if used near term. Possible association with gastroschisis in first trimester from some studies, but not confirmed.
Unknown whether fluticasone propionate is excreted in human breast milk. Other corticosteroids are excreted in breast milk in low amounts, and inhaled doses result in negligible systemic levels, predicting unlikely significant infant exposure. M/P ratio not determined. Caution advised; weigh risk of maternal obstructive airway disease exacerbation against potential infant risks (adrenal suppression, growth retardation).
Excreted into breast milk in low concentrations; M/P ratio not established. Limited data suggest no adverse effects in infants. American Academy of Pediatrics considers compatible with breastfeeding. Use with caution in preterm infants or those with tachycardia.
No specific dose adjustment required based on pharmacokinetic changes; pregnancy may cause decreased airway reactivity but no significant changes in fluticasone clearance. Maintain lowest effective dose to control asthma. No dose increase recommended solely due to pregnancy. Monitor asthma control and adjust dose as per standard guidelines.
No specific dose adjustment required for pregnancy. Pharmacokinetics may be altered due to increased plasma volume and renal clearance, but clinical significance is minimal. Use lowest effective dose to control symptoms.
AEROLONE is a combination inhaler containing an inhaled corticosteroid (fluticasone propionate) and a long-acting beta2-agonist (salmeterol). Advise patients to rinse mouth with water after each use to reduce risk of oral candidiasis. Not for acute bronchospasm; use a rescue inhaler (short-acting beta agonist) as needed. Monitor for increased heart rate, palpitations, or tremor. Do not stop abruptly; taper dose under medical supervision if discontinuing.
Monitor for paradoxical bronchospasm; use with caution in patients with cardiovascular disorders due to beta-adrenergic stimulation; may cause hypokalemia with high doses; combine with ipratropium for acute exacerbations; not recommended for long-term control without anti-inflammatory therapy.
Use AEROLONE exactly as prescribed; do not exceed recommended dose.,Rinse your mouth with water after each use (do not swallow) to prevent thrush.,This medication is not for sudden breathing problems; always keep your rescue inhaler (e.g., albuterol) with you.,Do not stop using this medicine without talking to your doctor, as stopping suddenly may worsen your breathing.,Seek immediate medical help if you experience worsening asthma, chest pain, or allergic reaction.
Use only as prescribed; do not exceed recommended dose.,Rinse mouth after use to prevent oral candidiasis (if using with corticosteroid), but albuterol alone does not require rinsing.,Seek emergency care if symptoms worsen or inhaler provides less relief.,Shake inhaler well before each use; use spacer if available for better delivery.,Monitor for palpitations, tremors, or nervousness; report if severe.
