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.
Solu-Cortef (hydrocortisone sodium succinate) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators, including prostaglandins and leukotrienes. It also inhibits immune cell migration and activation.
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.
100-1000 mg intravenous (IV) or intramuscular (IM), then 100-500 mg IV or IM every 2-6 hours as needed.

Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
Terminal elimination half-life: 1.5-2 hours (hydrocortisone); clinical duration of action is longer due to genomic effects (6-8 hours).
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 17-hydroxycorticosteroids) and <5% unchanged. Biliary/fecal: minimal (<5%).
