ARISTOCORT vs METICORTELONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis; modulates gene expression and immune cell activity.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
Intramuscular: 40-80 mg every 2-4 weeks; Intra-articular: 5-40 mg depending on joint size; Intralesional: 2.5-25 mg; Oral: 4-12 mg/day divided every 6-12 hours.
Prednisolone: 5-60 mg orally once daily or divided twice daily; methylprednisolone: 4-48 mg orally once daily or divided twice daily. Dose and duration vary by indication.

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
Terminal elimination half-life: 3.0-3.5 hours; clinical context: requires multiple daily doses for sustained effect; biological half-life (duration of HPA suppression) longer (~24-36 hours) due to intracellular activity
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
Renal: <5% unchanged; hepatic metabolism to inactive metabolites, primarily conjugated and excreted in urine; <2% fecal
