COLOCORT vs PREDNISONE INTENSOL
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.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
5-60 mg orally once daily or divided twice daily, titrated to response.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
2-4 hours (terminal) for prednisone; prednisolone half-life 2-4 hours. Clinical context: shorter than anti-inflammatory effect due to delayed receptor-mediated action.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal: <30% unchanged; major metabolites (prednisolone, 20-dihydroprednisolone) conjugated and excreted in urine. Fecal: <10%.
