Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Betamethasone is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, suppress immune response, and alter connective tissue response.
Topical corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine release, thereby exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
Adults: 1 gram intravenously every 24 hours. For severe infections, 1 gram every 12 hours may be used.
Topical: Apply a thin film to affected area 2-4 times daily. Rectal: Insert one suppository (25 mg) rectally twice daily (morning and evening) for 2-3 weeks, then taper as needed.

Terminal elimination half-life is 8-12 hours in adults with normal renal function, allowing twice-daily dosing.
Terminal elimination half-life is 1.5-2.5 hours; clinical duration of action is longer due to genomic effects lasting 8-12 hours.
Renal elimination of unchanged drug accounts for approximately 60-70% of the dose; biliary excretion contributes about 20-25%, with the remainder eliminated via feces.
Renal (approximately 70% as inactive metabolites, <5% unchanged); fecal (approximately 30%)
