Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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: 1-2 inhalations (90-180 mcg) twice daily; maximum 720 mcg twice daily.
2 inhalations (84 mcg) 3-4 times daily via oral inhalation.

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.
Terminal elimination half-life is approximately 2.8 hours in adults; prolonged in patients with hepatic impairment.
Renal: ~60% as metabolites, fecal: ~40% as metabolites. Less than 10% unchanged in urine.
Primarily hepatic metabolism; <10% excreted unchanged in urine, <5% in feces.
