Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; anti-inflammatory transcription factor modulation; inhibits phospholipase A2, reduces arachidonic acid release, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and inflammatory cell migration.
Corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.
Apply a thin layer to affected area twice daily. Max 60 g/week.

Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Terminal elimination half-life: 1-2 hours (topical use); 3-4 hours (systemic absorption after topical application to large areas or occluded skin). Clinical context: short half-life allows once- or twice-daily dosing.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
Renal: <1% as unchanged drug; biliary/fecal: minimal; primarily hepatic metabolism with metabolites excreted renally.
