Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits squalene epoxidase, 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.
1% cream applied topically once daily for 2 weeks for tinea pedis, 1 week for tinea corporis/cruris.
Adults: 200 mg orally twice daily.

Terminal elimination half-life is approximately 35–40 hours following topical application; long half-life supports once-daily dosing.
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 metabolized in the liver; minimal excretion of unchanged drug. Less than 5% of a topical dose is absorbed systemically; excreted in urine and feces as 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.
