ARISTOCORT vs ARISTOCORT A
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.
Triamcinolone acetonide is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, suppress cytokine production, and decrease inflammation and immune responses.
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.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
Terminal half-life: 2-3 hours for triamcinolone acetonide. Clinical context: Duration of action longer due to receptor binding and intracellular activity; anti-inflammatory effects persist 24-48 hours after IM administration.
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
