AIRSUPRA vs PULMICORT FLEXHALER
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.
Budesonide is a corticosteroid with potent anti-inflammatory effects. It inhibits multiple inflammatory cell types and mediators such as cytokines, chemokines, and adhesion molecules, reducing airway hyperresponsiveness and inflammation.
2 inhalations (albuterol 180 mcg / budesonide 160 mcg) orally inhaled twice daily (morning and evening), maximum 2 inhalations twice daily.
Inhalation: 1-2 inhalations (90-180 mcg) twice daily; maximum 720 mcg twice daily.

Budesonide: 2-3 hours; formoterol: 10-14 hours; clinical context: steady state achieved within days for both
Terminal half-life: 2.0-3.5 hours (mean 2.5 h) in adults after inhalation. Clinically, duration of effect may persist beyond pharmacokinetic half-life due to receptor binding.
Budesonide: ~60% renal as metabolites, ~40% fecal; formoterol: ~60% renal, ~40% fecal
Renal: ~60% as metabolites, fecal: ~40% as metabolites. Less than 10% unchanged in urine.
