Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune responses, and inhibit phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Hydrocortisone is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions by binding to cytoplasmic glucocorticoid receptors, which then translocate to the nucleus and modulate gene expression, leading to suppression of inflammatory mediators (e.g., prostaglandins, leukotrienes) and inhibition of immune cell migration. Pramoxine is a local anesthetic that reversibly blocks sodium ion channels in nerve membranes, thereby inhibiting initiation and conduction of sensory nerve impulses.
Hydrocortisone (Cort-Dome) typical adult dose: 100 mg intravenously or intramuscularly as a loading dose, followed by 50-100 mg intravenously every 6 hours for stress dosing; for replacement therapy: oral 20-30 mg daily in divided doses. Topical: apply sparingly to affected area 1-4 times daily.
Rectal aerosol foam: 1 applicatorful (6.5% pramoxine HCl / 1% hydrocortisone) rectally 2-3 times daily. Maximum 4 weeks.

Plasma half-life is approximately 1-2 hours; biological half-life (duration of adrenal suppression) is 18-36 hours.
The terminal elimination half-life of hydrocortisone is approximately 1.5-2 hours. After topical application to the rectal mucosa, systemic absorption is minimal, resulting in a half-life comparable to that of endogenous cortisol, with clinical effects lasting about 6-8 hours.
Primarily hepatic metabolism; renal excretion of inactive metabolites accounts for approximately 40-60% of elimination; less than 5% excreted unchanged in urine; biliary/fecal elimination is minor (<5%).
Hydrocortisone is metabolized in the liver, primarily to inactive metabolites (tetrahydrocortisone and tetrahydrocortisol). Less than 1% of the dose is excreted unchanged in urine. Fecal excretion is negligible.
