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.
Glucocorticoid receptor agonist; anti-inflammatory transcription factor modulation; inhibits phospholipase A2, reduces arachidonic acid release, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and inflammatory cell migration.
1-2 mL (6-12 mg/mL betamethasone acetate and betamethasone sodium phosphate) intramuscularly or intralesionally, repeat every 1-4 weeks as needed.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.

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 is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Renal: ~65% as metabolites and unchanged drug; biliary/fecal: ~20%; remainder via other pathways.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
