FOCINVEZ vs GRIS-PEG
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.
Griseofulvin binds to and disrupts microtubule function by interfering with the polymerization of tubulin, thereby inhibiting fungal cell mitosis and nucleic acid synthesis.
Intravenous: 1.5 mg/kg every 6 hours; maximum single dose: 200 mg.
For tinea capitis and other dermatophyte infections: 500 mg oral daily as a single dose or in divided doses. For more severe infections, up to 1 g daily in divided doses.

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 elimination half-life 14-24 hours. With continuous therapy, time to steady-state is ~3-5 days.
Renal: 70% (unchanged drug), Biliary/Fecal: 20% (metabolites), Other: 10% (minor pathways).
Primarily renal (as glucuronide conjugates): ~80%; fecal/biliary: ~10-15%; unchanged drug <1%.
