DECADRON-LA vs PEDIAPRED
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 glucocorticoid receptor agonist that binds to the intracellular glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production (e.g., IL-1, IL-6, TNF-alpha). It also suppresses immune responses by reducing lymphocyte proliferation and activity.
Dexamethasone acetate (DECADRON-LA) 8-16 mg intramuscularly every 1-3 weeks; adjust based on response and tolerance.
Oral: 5-60 mg/day as a single dose or divided doses; adjust based on condition and response.

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.
2.5–3.5 hours (terminal) in children; clinical context: requires multiple daily doses for sustained effect.
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%).
Renal: ~80% as metabolites (mainly glucuronides and sulfates) and <5% unchanged; fecal: ~15%.
