A-HYDROCORT vs MEDROL ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a corticosteroid hormone that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, inhibit immune response, and regulate metabolism.
Methylprednisolone acetate is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators including prostaglandins, leukotrienes, and cytokines.
Adrenal insufficiency: oral 20-30 mg/day in divided doses; inflammatory conditions: 5-60 mg/day oral; IV/IM: hydrocortisone sodium succinate 50-100 mg every 4-6 hours.
4 to 48 mg orally once daily or in divided doses (e.g., 4 mg every 6 hours) depending on condition, typically starting at 4-48 mg/day. Also intramuscular (IM) as methylprednisolone acetate: 40-120 mg every 1-4 weeks. Intra-articular or soft tissue: 4-40 mg per injection depending on joint size.

Terminal half-life: 1.5-2 hours (cortisol); clinical effect persists 8-12 hours due to glucocorticoid receptor binding
Terminal elimination half-life of methylprednisolone (active form) is approximately 1.8–3.5 hours. The biological half-life (duration of HPA suppression) is longer: 18–36 hours. Clinical context: Short plasma half-life but prolonged tissue effects due to receptor binding.
Renal (primarily as metabolites, <1% unchanged); biliary/fecal (<5%)
Primarily renal (urinary) as inactive metabolites. Approximately 10-20% of the dose is excreted unchanged in urine. Biliary/fecal excretion accounts for <5% of the dose.
