FLOVENT DISKUS 250 vs PREDNISOLONE ACETATE
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.
Glucocorticoid receptor agonist; modulates gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and NF-κB; suppresses immune response and inflammation.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).
5-60 mg orally once daily or divided every 12-24 hours; dose depends on condition and severity. For acute exacerbations, 200-400 mg intramuscularly once.

Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Terminal elimination half-life: 2-4 hours (plasma); biological (tissue) half-life: 18-36 hours due to prolonged glucocorticoid receptor-mediated effects. Half-life prolonged in hepatic disease.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
Renal (fraction excreted unchanged: <1%); primarily hepatic metabolism to inactive glucuronide and sulfate conjugates eliminated renally and fecally. After oral administration, 12-15% of dose recovered in bile/feces as metabolites.
