DECADRON-LA vs H-CORT
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.
H-CORT (hydrocortisone) is a corticosteroid with glucocorticoid and mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Dexamethasone acetate (DECADRON-LA) 8-16 mg intramuscularly every 1-3 weeks; adjust based on response and tolerance.
Intravenous: 100-250 mg as a single dose or up to 1 gram daily for acute conditions. Oral: 20-30 mg daily in divided doses. Maintenance: 5-20 mg daily.

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.
Terminal elimination half-life: 1.5-2 hours. Clinical context: Short half-life requires q4-6h dosing; duration may be 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%).
Renal: ~80% as metabolites, ~5% unchanged; biliary/fecal: ~15%
