DECADRON-LA vs TEXACORT
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.
TEXACORT (hydrocortisone) is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, immunosuppressive, and metabolic effects.
Dexamethasone acetate (DECADRON-LA) 8-16 mg intramuscularly every 1-3 weeks; adjust based on response and tolerance.
50 mg intravenously every 6 hours as a single agent or in combination with other antineoplastic agents.

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: 3-4 hours. In renal impairment, half-life may be prolonged up to 12 hours.
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: 80-90% as unchanged drug and inactive metabolites; biliary/fecal: 10-20%.
