Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI); inhibits serotonin transporter (SERT) in the presynaptic terminal, increasing synaptic serotonin levels.
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.

Terminal elimination half-life is 12.4 hours (range 11.2–14.1 hours) in patients with normal renal function; allows twice-daily dosing for steady-state within 3 days.
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.
Renal excretion of unchanged drug accounts for approximately 65% of elimination; biliary/fecal excretion accounts for 25%; the remaining 10% is metabolized by hepatic CYP3A4-mediated oxidation.
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.
