COLOCORT vs DEXACEN-4
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.
Dexamethasone is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to increased transcription of anti-inflammatory proteins and suppression of pro-inflammatory mediators.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
