AIRSUPRA vs ARMONAIR DIGIHALER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AIRSUPRA is a fixed-dose combination of albuterol (a short-acting beta2-agonist) and budesonide (an inhaled corticosteroid). Albuterol relaxes bronchial smooth muscle via beta2-adrenergic receptor activation, increasing cAMP and causing bronchodilation. Budesonide reduces airway inflammation by binding to glucocorticoid receptors, modulating gene transcription to suppress inflammatory mediators.
ARMONAIR DIGIHALER contains fluticasone furoate and umeclidinium, and vilanterol. Fluticasone furoate is a corticosteroid that exerts anti-inflammatory effects by binding to glucocorticoid receptors, modulating gene expression to reduce inflammatory mediators. Umeclidinium is a long-acting muscarinic antagonist (LAMA) that blocks acetylcholine at M3 receptors, causing bronchodilation. Vilanterol is a long-acting beta2-adrenergic agonist (LABA) that stimulates beta2 receptors, leading to smooth muscle relaxation and bronchodilation.
2 inhalations (albuterol 180 mcg / budesonide 160 mcg) orally inhaled twice daily (morning and evening), maximum 2 inhalations twice daily.
2 inhalations (55 mcg each) orally twice daily for maintenance treatment of airflow obstruction in chronic obstructive pulmonary disease (COPD).

Budesonide: 2-3 hours; formoterol: 10-14 hours; clinical context: steady state achieved within days for both
Terminal elimination half-life of unchanged arformoterol is approximately 26 hours (range 21-30 hours). This supports twice-daily dosing with approximately 2 days to steady state.
Budesonide: ~60% renal as metabolites, ~40% fecal; formoterol: ~60% renal, ~40% fecal
Renal: approximately 70% as unchanged drug; biliary/fecal: approximately 30%
