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.
Beclomethasone dipropionate is a corticosteroid that exerts anti-inflammatory effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing inflammatory cell migration and cytokine production in the airways.
Inhalation: 200-800 mcg twice daily for maintenance; maximum 1600 mcg/day. Nebulization: 0.5-1 mg twice daily.
2 inhalations (84 mcg) 3-4 times daily via oral inhalation.

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 elimination half-life is approximately 2.8 hours in adults; prolonged in patients with hepatic impairment.
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.
Primarily hepatic metabolism; <10% excreted unchanged in urine, <5% in feces.
