CORTEF ACETATE vs POHERDY
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.
POHERDY is a monoclonal antibody targeting the human epidermal growth factor receptor 2 (HER2), binding to domain IV of the extracellular segment, thereby inhibiting ligand-independent HER2 signaling and mediating antibody-dependent cellular cytotoxicity (ADCC).
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.
POHERDY: No approved drug. No dosing available.

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.
Terminal half-life 12–18 hours (mean 15 h); requires dose adjustment in renal impairment (CrCl <30 mL/min)
Primarily renal as inactive metabolites; less than 5% unchanged. Biliary/fecal elimination is minimal (<2%).
Renal: 60% unchanged; fecal/biliary: 30%; 10% metabolized
