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: 100-200 mg IV as initial dose, then 50-100 mg IV every 6 hours, or 0.18 mg/kg/h IV continuous infusion.
Rectal aerosol foam: 1 applicatorful (6.5% pramoxine HCl / 1% hydrocortisone) rectally 2-3 times daily. Maximum 4 weeks.

2–4 hours (terminal); prolonged in renal impairment.
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: 90% as unchanged drug; fecal: 10%.
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.
