CORTENEMA vs DELTASONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, leading to altered gene expression and suppression of inflammatory mediators, immune cells, and cytokine production.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
5-60 mg orally once daily or divided twice daily; dose individualized based on condition and response.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
The terminal elimination half-life of prednisolone (active form) is 2.1–3.5 hours. In clinical context, this short half-life supports once-daily to twice-daily dosing for anti-inflammatory effects, but adrenal suppression can persist longer due to receptor binding.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Prednisone is a prodrug converted to prednisolone. Prednisolone is metabolized primarily in the liver. Renal excretion of unchanged drug is negligible (<1%). Metabolites are excreted renally (approximately 80% as glucuronides and sulfates) and to a small extent in feces (<5%). Biliary excretion is minimal.
