A-METHAPRED vs CORTENEMA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines, prostaglandins, and leukotrienes. It also induces lipocortin synthesis, inhibits phospholipase A2, and reduces immune cell activity.
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.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
