ARISTOCORT vs FLO-PRED
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 that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, suppress immune response, and inhibit phospholipase A2, decreasing prostaglandin and leukotriene synthesis.
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.
Initial: 5-60 mg orally daily in divided doses; maintenance: 5-15 mg orally daily. Also available as ophthalmic suspension (1 drop 2-4 times daily).

Plasma: 1-2 hours (triamcinolone); tissue half-life 18-36 hours due to receptor binding and slow release from tissues.
The terminal elimination half-life of prednisolone is approximately 2-4 hours (mean ~3 hours) in adults with normal hepatic function. This short half-life allows for once-daily or alternate-day dosing to minimize adrenal suppression.
Renal (primarily as inactive metabolites); <5% unchanged. Biliary/fecal elimination minor.
FLO-PRED (prednisolone acetate) is primarily eliminated via hepatic metabolism, with inactive metabolites excreted renally. Approximately 20-30% of a dose is excreted unchanged in urine, and less than 5% is eliminated via biliary/fecal routes.
