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.
Orasone (prednisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, immune response, and adrenal function.
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.
Adults: 5-60 mg orally once daily or divided twice daily; typical starting dose 5-40 mg/day. Route: oral. Frequency: once daily or every 12 hours.

Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Terminal half-life of 3-4 hours for prednisolone (active metabolite of ORASONE); clinically, duration of HPA-axis suppression is more relevant (12-36 hours) with longer effects at higher doses.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
Primarily renal: ~80% as 17-keto metabolites and unchanged drug; biliary/fecal excretion accounts for <10%.
