DECADRON-LA vs LIQUID PRED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to produce anti-inflammatory and immunosuppressive effects; suppresses migration of polymorphonuclear leukocytes, reverses increased capillary permeability, and reduces cytokine production.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
Dexamethasone acetate (DECADRON-LA) 8-16 mg intramuscularly every 1-3 weeks; adjust based on response and tolerance.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

Terminal elimination half-life is approximately 3-4 hours for dexamethasone, but due to the acetate ester in Decadron-LA, absorption is prolonged, leading to an extended duration of action. The apparent half-life after intramuscular administration is about 3-4 days (72-96 hours) due to slow release from the injection site.
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Renal (<5% unchanged), hepatic metabolism with inactive metabolites excreted renally and fecally; urine and bile are minor routes. Exact % not specified for Decadron-LA (dexamethasone acetate), but dexamethasone is predominantly metabolized and metabolites are excreted renally (~80% of dose) and fecally (~20%).
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
