Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DEXAIR (dexamethasone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., cytokines, prostaglandins). It also inhibits leukocyte infiltration and reduces capillary permeability.
Hydrocortisone acetate is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, vasodilation, and immune cell activity. Pramoxine hydrochloride is a local anesthetic that reversibly blocks sodium ion channels in nerve cell membranes, inhibiting nerve impulse conduction and providing topical anesthesia.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Apply a thin film to affected area three to four times daily. Topical only.

Terminal elimination half-life: 3.0-4.5 hours in adults with normal renal function; prolonged to 8-12 hours in severe renal impairment (CrCl <30 mL/min).
Hydrocortisone acetate: 1.5–2 hours (plasma), clinically adrenocortical suppression lasts 24–48 hours; pramoxine: not applicable due to minimal absorption.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
Hydrocortisone acetate: primarily renal (about 90% as metabolites, less than 1% unchanged); pramoxine HCl: negligible systemic absorption, eliminated primarily via fecal excretion.
