Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing immune cell activity.
Agonist at glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
1-2 mL (6-12 mg/mL betamethasone acetate and betamethasone sodium phosphate) intramuscularly or intralesionally, repeat every 1-4 weeks as needed.
0.5-9 mg/day orally in divided doses every 6-12 hours; intravenously or intramuscularly as dexamethasone sodium phosphate; typical anti-inflammatory dose 0.75-9 mg/day. For cerebral edema: IV loading dose 10 mg, then 4 mg every 6 hours. For COVID-19: 6 mg IV or orally once daily for up to 10 days.

Plasma terminal half-life: betamethasone phosphate ~3-5 hours; betamethasone acetate ~6-8 hours. Clinical duration extended due to ester hydrolysis and depot effect (up to 7-14 days for IM injection).
Terminal elimination half-life: 3-5 hours in adults; slightly prolonged in neonates (approximately 12-24 hours) and patients with hepatic impairment. Clinical context: Duration of HPA axis suppression may exceed the presence of measurable drug; single dose typically suppresses cortisol for 24-36 hours.
Renal: ~65% as metabolites and unchanged drug; biliary/fecal: ~20%; remainder via other pathways.
Renal (primarily as glucuronide and sulfate conjugates) and biliary/fecal (minor). Approximately 65-80% of a dose is excreted in urine within 24 hours as 20-beta-dihydrodexamethasone (inactive) and conjugated metabolites; about 10-15% appears in feces. Less than 5% is excreted unchanged.
