METICORTEN vs VALISONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression and suppressing inflammation, immune response, and adrenal function.
Betamethasone valerate is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), which control the release of arachidonic acid from membrane phospholipids, thereby inhibiting prostaglandin and leukotriene synthesis. It has anti-inflammatory, antipruritic, and vasoconstrictive effects.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum duration: 2 weeks.

Following oral or IV administration, the terminal elimination half-life of total prednisolone (active form) is 2.1–3.5 hours in adults with normal hepatic function. In hepatic impairment, half-life may be prolonged (up to 6–8 hours), necessitating dose adjustment.
Approximately 1.7 hours after topical application; systemic half-life is short due to rapid metabolism.
Primarily renal: approximately 80% as inactive metabolites (conjugated and oxidized forms) and <5% as unchanged prednisolone. Biliary/fecal excretion accounts for about 10-15% of the dose.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal elimination accounts for <10%.
