DELTA-CORTEF vs ORTIKOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
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.
Prednisolone (DELTA-CORTEF) typical adult dose: 5-60 mg orally once daily or in divided doses, depending on condition. For acute exacerbations: 20-60 mg orally daily. Route: oral. Frequency: once daily or divided.
2 mg orally three times daily (total daily dose 6 mg).

Terminal elimination half-life: 1.5-2.5 hours (mean ~2 hours) for prednisolone; clinical context: short-acting glucocorticoid, requires multiple daily dosing for sustained anti-inflammatory effect, adrenocortical suppression lasts approximately 1.25-1.5 days after discontinuation.
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: approximately 80-90% as unchanged drug and metabolites (primarily 20β-dihydrocortisone and other inactive conjugates); biliary/fecal: <10%.
Renal (70% unchanged), biliary/fecal (30% as metabolites)
