Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, suppress immune response, and inhibit phospholipase A2, decreasing prostaglandin and leukotriene synthesis.
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.
Initial: 5-60 mg orally daily in divided doses; maintenance: 5-15 mg orally daily. Also available as ophthalmic suspension (1 drop 2-4 times daily).
250 mcg inhaled orally via DISKUS twice daily (500 mcg total daily dose).

The terminal elimination half-life of prednisolone is approximately 2-4 hours (mean ~3 hours) in adults with normal hepatic function. This short half-life allows for once-daily or alternate-day dosing to minimize adrenal suppression.
Approximately 10-12 hours (terminal elimination half-life in asthmatics).
FLO-PRED (prednisolone acetate) is primarily eliminated via hepatic metabolism, with inactive metabolites excreted renally. Approximately 20-30% of a dose is excreted unchanged in urine, and less than 5% is eliminated via biliary/fecal routes.
Renal (approximately 5% as unchanged drug); fecal (majority as metabolites and unabsorbed drug).
