Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, modulating transcription of anti-inflammatory proteins and suppressing immune response.
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.
Apply topically to affected area twice daily.
Rectal aerosol foam: 1 applicatorful (6.5% pramoxine HCl / 1% hydrocortisone) rectally 2-3 times daily. Maximum 4 weeks.

Terminal elimination half-life: 1.5-2.5 hours. Clinical context: Short half-life necessitates multiple daily dosing for sustained anti-inflammatory effect; accumulation minimal with repeated dosing.
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.
Renal: 70-90% (as metabolites, mainly 6β-hydroxycortisol and other conjugates); Biliary/fecal: <10%; Unchanged drug: <5% in urine.
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.
