CORTENEMA vs MAXIDEX
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.
MAXIDEX (dexamethasone) is a potent glucocorticoid that binds to the glucocorticoid receptor (GR), leading to modulation of gene expression and inhibition of inflammatory mediators such as prostaglandins and leukotrienes. It suppresses immune response through inhibition of cytokine production (e.g., IL-1, IL-2, TNF-alpha) and reduces vasodilation and vascular permeability.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
One to two drops of the 0.1% ophthalmic suspension into the conjunctival sac every hour during the day and every two hours at night initially; after improvement, reduce to one drop every four hours, then one drop three to four times 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 approximately 2-3 hours for dexamethasone; in ocular tissues, half-life may be prolonged due to local retention, but systemic half-life is short with minimal accumulation.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Primarily hepatic metabolism via CYP3A4; renal excretion of metabolites accounts for <15% unchanged drug; biliary/fecal elimination of metabolites predominates.
