FOCINVEZ vs NOXAFIL POWDERMIX KIT
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.
Posaconazole inhibits fungal CYP450-dependent 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Intravenous: 1.5 mg/kg every 6 hours; maximum single dose: 200 mg.
300 mg (one 300-mg vial) intravenously twice on day 1, then 300 mg intravenously once daily starting on day 2. Alternatively, oral suspension: 200 mg (10 mL) three times daily. For prophylaxis, IV: 300 mg twice on day 1, then 300 mg once daily; oral: 200 mg three times daily.

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).
The terminal elimination half-life is approximately 27 hours (range 20-66 hours) in healthy subjects, allowing for once-daily dosing after steady state.
Renal: 70% (unchanged drug), Biliary/Fecal: 20% (metabolites), Other: 10% (minor pathways).
Posaconazole is primarily excreted in the feces (77%) as unchanged drug, with renal excretion accounting for 14% of the dose (primarily as glucuronide conjugates). Less than 0.2% is excreted unchanged in urine.
