BETAMETHASONE DIPROPIONATE vs PENECORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betamethasone dipropionate is a glucocorticoid receptor agonist that binds to cytosolic glucocorticoid receptors, leading to modulation of gene transcription. It suppresses pro-inflammatory cytokines (e.g., IL-1, IL-2, TNF-α), inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes mast cells.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
Apply topically as 0.05% cream, ointment, or lotion to affected area once or twice daily. Maximum: 45 g/week.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.

Terminal elimination half-life: 6-8 hours (parenteral); clinically, duration of adrenal suppression may extend beyond this.
Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Renal, ~75% as conjugated metabolites; biliary/fecal, ~25%.
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
