Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Methylprednisolone is a glucocorticoid receptor agonist. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, chemokines, and adhesion molecules. It also inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).
4 to 48 mg/day orally or intramuscularly in divided doses every 12 hours; for acute conditions, up to 120 mg/day intravenously in divided doses every 4-6 hours.

Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Terminal elimination half-life: 2–4 hours. Clinical context: shorter than other corticosteroids; requires multiple daily doses for sustained anti-inflammatory effect.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
Primarily hepatic metabolism; <20% excreted unchanged in urine. Negligible biliary/fecal elimination.
