Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colocort (hydrocortisone acetate) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune responses.
Fluticasone propionate is a synthetic trifluorinated corticosteroid with potent anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as cytokines, leukotrienes, and prostaglandins. It reduces airway hyperresponsiveness and suppresses eosinophil activity.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
The terminal elimination half-life of fluticasone propionate is approximately 7.8 hours (range 5-11 hours) following inhalation. This supports twice-daily dosing, though the therapeutic effect is driven by local lung retention rather than systemic half-life.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Fluticasone propionate is primarily eliminated via hepatic metabolism (CYP3A4) with less than 5% of a dose excreted unchanged in urine. Fecal excretion accounts for approximately 90% of the absorbed dose (as metabolites). Biliary elimination is minimal.
