FOCINVEZ vs FULVICIN P/G 330
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FOCINVEZ is a small-molecule inhibitor of the interaction between the N-terminal domain of the androgen receptor (AR) and the AR N-terminal domain coactivator binding site, thereby blocking AR-mediated gene transcription and inhibiting prostate cancer cell growth.
Fulvicin P/G 330 contains griseofulvin, which inhibits fungal cell mitosis by disrupting the microtubule function, binding to tubulin and preventing assembly of spindle fibers during metaphase.
Intravenous: 1.5 mg/kg every 6 hours; maximum single dose: 200 mg.
330 mg orally once daily with fatty meal to enhance absorption.

Terminal elimination half-life: 12-15 hours; allows twice-daily dosing in most patients, extended in renal impairment (up to 30-40 hours in severe impairment).
Terminal half-life approximately 9-22 hours in adults, with a mean of ~13 hours. Clinical context: steady-state achieved in 2-3 days; may guide dosing interval.
Renal: 70% (unchanged drug), Biliary/Fecal: 20% (metabolites), Other: 10% (minor pathways).
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites: ~36% in feces, ~13% in urine.
