Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; inhibits inflammatory mediators, reduces airway edema and mucus secretion.
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.
Inhalation: 200-800 mcg twice daily for maintenance; maximum 1600 mcg/day. Nebulization: 0.5-1 mg twice daily.
Inhalation: 1-2 inhalations (90-180 mcg) twice daily; maximum 720 mcg twice daily.

The terminal elimination half-life of budesonide is approximately 2.0 to 3.6 hours in adults, with a mean of about 2.8 hours. This short half-life is consistent with its rapid clearance and lack of significant accumulation with once- or twice-daily dosing.
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 is primarily metabolized in the liver via CYP3A4 to inactive metabolites. Approximately 60% of the dose is excreted in urine as metabolites, and 40% in feces. Less than 10% of unchanged drug is excreted renally.
Renal: ~60% as metabolites, fecal: ~40% as metabolites. Less than 10% unchanged in urine.
