Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits fungal cytochrome P450 14α-demethylase, blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Inhibits fungal cytochrome P450 14α-demethylase (CYP51), blocking ergosterol synthesis and disrupting fungal cell membrane integrity.
Intravaginal administration: 100 mg (one applicatorful of 2% cream) once daily for 3 days; or 100 mg (one suppository) once daily for 3 days; or 5 g (one applicatorful of 4% cream) as a single dose.
IV: Loading dose of 6 mg/kg every 12 hours for 2 doses, then 4 mg/kg every 12 hours. Oral: Weight ≥40 kg: Loading dose of 400 mg every 12 hours for 2 doses, then 200 mg every 12 hours; weight <40 kg: Loading dose of 200 mg every 12 hours for 2 doses, then 100 mg every 12 hours.

Terminal half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
Terminal half-life is approximately 24 hours (range 12–30 h) in adults. Prolonged in hepatic impairment (Child-Pugh A: 48 h; B: 72 h).
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
Primarily hepatic metabolism; <2% excreted unchanged in urine. Fecal excretion accounts for ~80% of metabolites. Renal excretion of unchanged drug is negligible.
