FLOVENT DISKUS 250 vs METHYLPREDNISOLONE 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.
Methylprednisolone acetate is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene expression to suppress inflammation, immune response, and adrenal function. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and decreases cytokine production.
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).
40-80 mg intramuscular (IM) or intra-articular (IA) injection; for IM use, dose may be repeated every 1-4 weeks as needed. Maximum single IM dose: 120 mg.

Approximately 10-12 hours (terminal elimination half-life in asthmatics).
Terminal half-life: 3-3.5 hours; correlates with duration of anti-inflammatory effect due to receptor-mediated action.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
Renal: <10% unchanged; extensive hepatic metabolism to inactive metabolites primarily excreted renally as glucuronides and sulfates.
