CORTENEMA vs PREDNISOLONE SODIUM PHOSPHATE
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.
Agonist of glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of pro-inflammatory cytokines, and suppression of immune cell activity.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
Initial dose: 5-60 mg orally or intravenously once daily or divided every 12-24 hours; range 5-60 mg/day. For acute conditions, 40-60 mg once daily.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Terminal elimination half-life is 2.1–3.5 hours in adults (mean 2.6 h). Clinical context: Short half-life supports twice-daily dosing for most conditions; prolonged in hepatic impairment (up to 8 h).
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Renal excretion of inactive metabolites (primarily prednisolone) accounts for >80% of elimination; less than 10% excreted unchanged. Biliary/fecal excretion is negligible (<5%).
