ENTOCORT EC vs ORTIKOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Budesonide is a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to anti-inflammatory effects via inhibition of inflammatory mediators such as cytokines and prostaglandins.
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.
9 mg orally once daily in the morning for up to 8 weeks.
2 mg orally three times daily (total daily dose 6 mg).

Terminal elimination half-life is approximately 2-3 hours; clinically, the extended intestinal release formulation maintains local activity despite short systemic half-life.
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 fecal (60-70%) with minimal renal excretion (<10%); extensively metabolized hepatically, metabolites excreted in bile and feces.
Renal (70% unchanged), biliary/fecal (30% as metabolites)
