CORTEF ACETATE vs VANOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory and immunosuppressant activity; binds to glucocorticoid receptors, modulating gene expression and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
VANOS (fluocinonide 0.1% cream) is a corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2 and reduction of prostaglandin and leukotriene synthesis, resulting in anti-inflammatory, antipruritic, and vasoconstrictive effects.
Adult: 5-60 mg orally every 6-12 hours (hydrocortisone base equivalent), or 10-240 mg IV/IM every 12 hours (as hydrocortisone sodium succinate). Dose depends on severity and condition.
Apply a thin layer to affected areas once or twice daily. Not for use longer than 2 weeks; maximum 15 g per day.

Plasma terminal half-life is approximately 1.5-2 hours. However, biologic half-life (duration of adrenal suppression) is 18-36 hours due to intracellular receptor binding.
The terminal elimination half-life is approximately 7.5 hours (range 5-12 hours). This supports twice-daily or once-daily dosing for sustained local effect.
Primarily renal as inactive metabolites; less than 5% unchanged. Biliary/fecal elimination is minimal (<2%).
Primarily renal excretion (glucuronidation and sulfation); minimal biliary elimination (<5%). Approximately 60-70% of the dose is excreted in urine as metabolites, with <1% unchanged.
