FOCINVEZ vs NILSTAT
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.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and cause leakage of intracellular contents, leading to fungal cell death.
Intravenous: 1.5 mg/kg every 6 hours; maximum single dose: 200 mg.
Topical: Apply 100,000 units/g cream or ointment to affected area twice daily. Oral suspension: 100,000 units/mL; 4-6 mL swish and swallow four times daily for 14 days. Oral tablets: 500,000 units; 1-2 tablets 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).
Not well-defined due to minimal systemic absorption following oral or topical administration; estimated to be <1 hour in systemic circulation if absorbed.
Renal: 70% (unchanged drug), Biliary/Fecal: 20% (metabolites), Other: 10% (minor pathways).
Primarily via feces as unchanged drug; negligible urinary excretion (<1%).
