DEXONE 4 vs ORTIKOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
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.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
2 mg orally three times daily (total daily dose 6 mg).

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Terminal half-life of 8 hours (range 6-10) in healthy adults; prolonged to 24 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Renal (70% unchanged), biliary/fecal (30% as metabolites)
