Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ciclesonide is a prodrug that is converted to the active metabolite des-ciclesonide, which has anti-inflammatory activity by binding to glucocorticoid receptors, thereby inhibiting inflammatory mediators such as cytokines and leukotrienes.
Beclomethasone dipropionate is a corticosteroid with anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, reduced arachidonic acid release, and decreased synthesis of prostaglandins and leukotrienes. It also suppresses cytokine production, adhesion molecule expression, and eosinophil survival, thereby reducing airway inflammation.
Inhalation: 160 mcg twice daily (morning and evening). May be increased to 320 mcg twice daily if inadequate response. Maximum 640 mcg twice daily.
2 inhalations (168 mcg beclomethasone dipropionate) twice daily via oral inhalation.

Terminal elimination half-life is approximately 2-3 hours for the systemically absorbed fraction; however, the receptor occupancy half-life is significantly longer due to lipophilic tissue binding, providing therapeutic duration of 12 hours.
Terminal elimination half-life: 1.5–2 hours for beclomethasone dipropionate; 2.7 hours for active metabolite beclomethasone-17-monopropionate. Clinical context: supports twice-daily dosing.
Primarily hepatic metabolism (CYP3A4) to less active metabolites; renal excretion accounts for <10% unchanged; fecal excretion as metabolites ~80%.
Primarily hepatic metabolism; metabolites excreted renally (~90% as free and conjugated metabolites) and fecally (<10%).
