BREXAFEMME vs NATURAL ESTROGENIC SUBSTANCE-ESTRONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BREXAFEMME (ibrexafungerp) inhibits glucan synthase, an enzyme involved in fungal cell wall synthesis, disrupting cell wall integrity and causing fungal cell death.
Estrone binds to and activates estrogen receptors (ERα and ERβ), leading to modulation of gene transcription and subsequent estrogenic effects on target tissues.
200 mg orally once daily.
0.1 to 0.5 mg intramuscularly 2 to 3 times per week for estrogen replacement therapy

The terminal elimination half-life of ibrexafungerp is approximately 20-30 hours in healthy subjects, supporting once-daily oral dosing without need for a loading dose.
Terminal half-life: 24-48 hours (prolonged due to enterohepatic recirculation and tissue distribution).
Ibrexafungerp is primarily eliminated via the biliary/fecal route. In clinical studies, approximately 51% of the dose was recovered in feces (as unchanged drug and metabolites) and ~1% in urine. Renal excretion is negligible.
Renal: ~50% (as glucuronide and sulfate conjugates), Biliary/Fecal: ~50% (enterohepatic recirculation).
