DEXAMETHASONE SODIUM PHOSPHATE PRESERVATIVE FREE vs ORTIKOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone sodium phosphate is a corticosteroid with potent anti-inflammatory and immunosuppressant properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, inhibition of phospholipase A2, and reduction of inflammatory mediators like prostaglandins and leukotrienes.
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.
0.5-24 mg/day IV or IM in divided doses every 6-12 hours; acute conditions: 4-20 mg IV initially, then 2-4 mg every 4-6 hours.
2 mg orally three times daily (total daily dose 6 mg).

Terminal elimination half-life is 3-4 hours in adults; clinical context: biological effects persist >24 hours due to prolonged receptor binding.
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 renal (approximately 65-80% as free steroid and glucuronide conjugates); minor biliary/fecal elimination (10-15%).
Renal (70% unchanged), biliary/fecal (30% as metabolites)
