ARAZLO vs FLUOCINONIDE
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.
Fluocinonide is a potent corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced prostaglandin and leukotriene synthesis. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
Topical: Apply 0.045% gel once daily to affected areas of the face.
Topical: Apply a thin film to affected area 1-3 times daily. Limitation of use: Should not exceed 60 g per week in adults.

Clinical Note
moderateFluocinonide + Gatifloxacin
"The risk or severity of adverse effects can be increased when Fluocinonide is combined with Gatifloxacin."
Clinical Note
moderateFluocinonide + Rosoxacin
"The risk or severity of adverse effects can be increased when Fluocinonide is combined with Rosoxacin."
Clinical Note
moderateFluocinonide + Levofloxacin
"The risk or severity of adverse effects can be increased when Fluocinonide is combined with Levofloxacin."
Clinical Note
moderateTerminal half-life approximately 29 hours, supporting once-weekly topical application.
Terminal elimination half-life is approximately 1.3-2.4 hours in plasma. Clinically, due to high tissue binding and slow release from skin, the pharmacodynamic half-life for topical effect may extend to 12-24 hours.
Primarily fecal excretion of unchanged drug (≥90%) and biliary elimination; renal excretion accounts for <2%.
Primarily hepatic metabolism; inactive metabolites excreted renally and fecally. Renal elimination accounts for approximately 60-70% of total clearance, fecal elimination ~30-40%. Less than 1% excreted unchanged in urine.
