DEPO-MEDROL vs ORTIKOS
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.
ORTIKOS (acalabrutinib) is a selective, irreversible inhibitor of Bruton tyrosine kinase (BTK). It forms a covalent bond with the active site cysteine residue (Cys481) in BTK, blocking downstream B-cell receptor signaling and inhibiting malignant B-cell proliferation and survival.
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.
2 mg orally three times daily (total daily dose 6 mg).

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 half-life of 8 hours (range 6-10) in healthy adults; prolonged to 24 hours in severe renal impairment (CrCl <30 mL/min).
Primarily hepatic metabolism; renal excretion of metabolites (<10% unchanged). Fecal excretion is minor (<5%).
Renal (70% unchanged), biliary/fecal (30% as metabolites)
