BETAMETHASONE VALERATE vs CORTIFOAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betamethasone valerate is a corticosteroid that binds to the glucocorticoid receptor, leading to increased synthesis of lipocortin, which inhibits phospholipase A2 and reduces arachidonic acid release, thereby decreasing prostaglandin and leukotriene production. It also suppresses cytokine expression and inflammatory cell migration.
Cortifoam (hydrocortisone acetate) is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, antipruritic, and vasoconstrictive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses immune cell migration and cytokine release.
Apply a thin film to affected area twice daily. Maximum 15 g/day for 2 weeks.
1 applicatorful (90 mg hydrocortisone acetate) rectally twice daily for 2-3 weeks, then every other day as needed.

Terminal elimination half-life is approximately 36–54 hours for the parent drug after topical application; systemic absorption is low. For oral or IV administration, the half-life is about 3–5 hours, but clinical effects persist longer due to receptor-mediated mechanisms.
Approximately 1.5-2 hours for hydrocortisone; clinically, effects persist longer due to local action.
Renal (primarily as metabolites, unchanged drug <5%). Biliary/fecal elimination accounts for a minor fraction. Essentially no significant renal excretion of active drug.
Primarily renal (about 70-90% as metabolites) and fecal (about 10-30% as metabolites).
