Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a synthetic corticosteroid with anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory transcription factors (e.g., NF-κB) and increased synthesis of lipocortin-1, which reduces phospholipase A2 activity and subsequent release of arachidonic acid metabolites (prostaglandins, leukotrienes). In the lungs, it decreases airway inflammation by reducing eosinophil infiltration, mast cell degranulation, and cytokine release.
Prednisolone is a glucocorticoid receptor agonist that binds to the intracellular glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production (e.g., IL-1, IL-6, TNF-alpha). It also suppresses immune responses by reducing lymphocyte proliferation and activity.
Inhalation aerosol: 88-880 mcg twice daily; typical starting dose: 88 mcg twice daily. Max: 880 mcg twice daily. Oral inhalation powder: 100-1000 mcg twice daily; typical starting: 100 mcg twice daily. Max: 1000 mcg twice daily.
Oral: 5-60 mg/day as a single dose or divided doses; adjust based on condition and response.

Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
2.5–3.5 hours (terminal) in children; clinical context: requires multiple daily doses for sustained effect.
Primarily hepatic metabolism (CYP3A4) with fecal excretion of metabolites; renal excretion accounts for <5% of the dose as unchanged drug and metabolites combined.
Renal: ~80% as metabolites (mainly glucuronides and sulfates) and <5% unchanged; fecal: ~15%.
