Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory effects via inhibition of inflammatory mediators such as cytokines and prostaglandins.
Fluticasone propionate is a corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, reduction of eosinophil recruitment, and suppression of airway hyperresponsiveness.
9 mg orally once daily in the morning for up to 8 weeks.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).

Terminal elimination half-life is approximately 2-3 hours; clinically, the extended intestinal release formulation maintains local activity despite short systemic half-life.
Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Primarily fecal (60-70%) with minimal renal excretion (<10%); extensively metabolized hepatically, metabolites excreted in bile and feces.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
