Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory and immunosuppressant activity; binds to glucocorticoid receptors, modulating gene expression and inhibiting phospholipase A2, thereby 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.
Adult: 5-60 mg orally every 6-12 hours (hydrocortisone base equivalent), or 10-240 mg IV/IM every 12 hours (as hydrocortisone sodium succinate). Dose depends on severity and condition.
Rectal aerosol foam: 1 applicatorful (6.5% pramoxine HCl / 1% hydrocortisone) rectally 2-3 times daily. Maximum 4 weeks.

Plasma terminal half-life is approximately 1.5-2 hours. However, biologic half-life (duration of adrenal suppression) is 18-36 hours due to intracellular receptor binding.
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 renal as inactive metabolites; less than 5% unchanged. Biliary/fecal elimination is minimal (<2%).
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.
