DEPO-MEDROL vs HYDROCORTISONE IN ABSORBASE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone acetate is a synthetic glucocorticoid receptor agonist that modulates gene expression to suppress inflammation, immune responses, and adrenal function by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
Glucocorticoid receptor agonist that modulates gene expression, leading to anti-inflammatory, immunosuppressive, and vasoconstrictive effects.
IV: 10-40 mg every 1-2 weeks; IM: 40-120 mg every 1-4 weeks; Intra-articular/soft tissue: 4-80 mg per injection, repeat every 1-5 weeks as needed.
Topical: Apply a thin layer to affected area 2-4 times daily.

Plasma terminal elimination half-life: 2.5-4.0 hours (methylprednisolone acetate formulation). Duration of adrenal suppression correlates with tissue esterase hydrolysis and prolonged tissue retention.
Terminal elimination half-life: 1-2 hours (plasma cortisol); biological half-life (duration of action) 8-12 hours due to intracellular receptor effects.
Primarily hepatic metabolism; renal excretion of metabolites (<10% unchanged). Fecal excretion is minor (<5%).
Renal: primarily as 17-hydroxycorticosteroids and 17-ketosteroids; <5% unchanged. Biliary/fecal: minimal. Metabolites conjugated with glucuronide or sulfate.
