Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a synthetic corticosteroid that binds to glucocorticoid receptors, increasing the synthesis of lipocortins, which inhibit phospholipase A2, thereby reducing arachidonic acid release and decreasing prostaglandin and leukotriene production. It also suppresses inflammatory cell migration and cytokine release, leading to reduced airway inflammation and hyperreactivity.
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.
Adult: 88-880 mcg twice daily via oral inhalation; typical starting dose: 88 mcg twice daily for patients previously on bronchodilators alone, 220 mcg twice daily for patients on inhaled corticosteroids.
100-1000 mg intravenous (IV) or intramuscular (IM), then 100-500 mg IV or IM every 2-6 hours as needed.

Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Terminal elimination half-life: 1.5-2 hours (hydrocortisone); clinical duration of action is longer due to genomic effects (6-8 hours).
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
Renal: ~80% as metabolites (mainly 17-hydroxycorticosteroids) and <5% unchanged. Biliary/fecal: minimal (<5%).
