AEROBID vs AEROSPAN HFA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aerobid (flunisolide) is a corticosteroid that binds to glucocorticoid receptors, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, reduction of eosinophil migration, and decreased airway hyperresponsiveness.
Corticosteroid that binds to glucocorticoid receptors, leading to inhibition of inflammatory mediators such as cytokines and phospholipase A2, and suppression of airway inflammation.
2 inhalations (250 mcg each) twice daily via oral inhalation; maximum 4 inhalations twice daily.
2 inhalations (160 mcg/flumetasone pivalate equivalent) twice daily by oral inhalation.

2.0–3.5 hours (terminal) after inhalation; rapid clearance supports twice-daily dosing.
Terminal elimination half-life is approximately 1.5-2 hours after inhalation. This short half-life is consistent with rapid systemic clearance and supports twice-daily dosing for maintenance therapy.
Renal elimination of inactive metabolites accounts for ~95% of dose; <10% excreted unchanged. Biliary/fecal elimination is minimal (<5%).
Renal excretion of metabolites (approximately 60-80%) and fecal elimination (approximately 12-24%). Unchanged drug is minimally excreted in urine (<1%).
