ARISTOCORT vs HYDELTRA-TBA
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.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
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.
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
