ARAZLO vs FLUOCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ARAZLO (tazarotene) is a retinoid prodrug that is converted to its active metabolite, tazarotenic acid, which binds to retinoic acid receptors (RARs), specifically RAR-β and RAR-γ, modulating gene expression to normalize epidermal differentiation, reduce keratinocyte proliferation, and decrease inflammation.
Fluocinolone acetonide is a potent corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress inflammatory cytokines (e.g., IL-1, IL-2, TNF-α). It also causes vasoconstriction and decreases cellular migration and immune response.
Topical: Apply 0.045% gel once daily to affected areas of the face.
Topical: Apply thin film to affected area 2-4 times daily. Otic: 0.01% solution, 5 drops into ear canal twice daily. Intralesional: 3.3 mg/mL, 0.5-1 mL per injection every 1-2 weeks.

Clinical Note
moderateFluocinolone acetonide + Gatifloxacin
"The risk or severity of adverse effects can be increased when Fluocinolone acetonide is combined with Gatifloxacin."
Clinical Note
moderateFluocinolone acetonide + Rosoxacin
"The risk or severity of adverse effects can be increased when Fluocinolone acetonide is combined with Rosoxacin."
Clinical Note
moderateFluocinolone acetonide + Levofloxacin
"The risk or severity of adverse effects can be increased when Fluocinolone acetonide is combined with Levofloxacin."
Clinical Note
moderateTerminal half-life approximately 29 hours, supporting once-weekly topical application.
Terminal elimination half-life is approximately 1.3-1.5 hours following topical application; after systemic absorption (oral or injection), half-life is 1.5-2.0 hours, necessitating multiple daily dosing for sustained effect.
Primarily fecal excretion of unchanged drug (≥90%) and biliary elimination; renal excretion accounts for <2%.
Primarily hepatic metabolism with renal excretion of metabolites (approximately 80% renal, 20% biliary/fecal). Less than 1% excreted unchanged in urine.
