Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing immune cell activity.
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.
1-2 mL (6-12 mg/mL betamethasone acetate and betamethasone sodium phosphate) intramuscularly or intralesionally, repeat every 1-4 weeks as needed.
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.

Plasma terminal half-life: betamethasone phosphate ~3-5 hours; betamethasone acetate ~6-8 hours. Clinical duration extended due to ester hydrolysis and depot effect (up to 7-14 days for IM injection).
Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Renal: ~65% as metabolites and unchanged drug; biliary/fecal: ~20%; remainder via other pathways.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
