JAVADIN vs ZYTIGA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
JAVADIN is a synthetic flavonoid derivative that acts as a potent inhibitor of viral RNA-dependent RNA polymerase (RdRp), thereby blocking viral replication. It also modulates the host immune response by upregulating interferon signaling and reducing pro-inflammatory cytokine production.
Abiraterone acetate is converted in vivo to abiraterone, an androgen biosynthesis inhibitor that selectively inhibits the enzyme CYP17 (17α-hydroxylase/C17,20-lyase). This inhibition blocks androgen production in the testes, adrenal glands, and prostate tumor tissue.

1000 mg orally once daily on an empty stomach, at least 1 hour before or 2 hours after a meal, in combination with prednisone 5 mg orally twice daily.

Terminal elimination half-life is 8.2 hours (range 6.5–10.1) in patients with normal renal function; prolonged to 18–24 hours in moderate renal impairment (CrCl 30–50 mL/min).
The terminal elimination half-life of abiraterone is approximately 12 hours (range 9–18 hours) following oral administration, supporting twice-daily dosing.
Renal elimination of unchanged drug accounts for 85% of clearance; biliary/fecal elimination accounts for 10%; 5% metabolized.
Abiraterone is primarily eliminated via hepatic metabolism with less than 1% excreted unchanged in urine. Approximately 88% of a radiolabeled dose is recovered in feces (mainly as metabolites) and about 5% in urine.
