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.
TOLAK (tazarotene) is a retinoid prodrug that is converted to its active metabolite tazarotenic acid, which binds selectively to retinoic acid receptors (RARs) such as RARβ and RARγ; this modulates gene expression involved in cell proliferation, differentiation, and inflammation.
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.
Adults: 200 mg orally twice daily.

Terminal half-life is approximately 21–24 hours, supporting once-daily or twice-weekly dosing for vaginal candidiasis.
The terminal elimination half-life of fluorouracil is approximately 10-20 minutes due to rapid catabolism by dihydropyrimidine dehydrogenase. Clinically, this short half-life necessitates continuous infusion for sustained systemic exposure.
Primarily hepatic metabolism with <5% excreted unchanged in urine; fecal elimination accounts for ~30% of metabolites.
Tolak (fluorouracil) is primarily eliminated via metabolism; less than 10% is excreted unchanged in urine. Fecal excretion accounts for approximately 10-20% of the administered dose.
