ARAZLO vs DIFLUPREDNATE
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.
Difluprednate is a potent corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress inflammatory mediators.
Topical: Apply 0.045% gel once daily to affected areas of the face.
Topical: Apply thin film to affected area twice daily.

Clinical Note
moderateDifluprednate + Gatifloxacin
"The risk or severity of adverse effects can be increased when Difluprednate is combined with Gatifloxacin."
Clinical Note
moderateDifluprednate + Rosoxacin
"The risk or severity of adverse effects can be increased when Difluprednate is combined with Rosoxacin."
Clinical Note
moderateDifluprednate + Levofloxacin
"The risk or severity of adverse effects can be increased when Difluprednate is combined with Levofloxacin."
Clinical Note
moderateTerminal half-life approximately 29 hours, supporting once-weekly topical application.
Terminal elimination half-life approximately 2–4 hours; clinically, duration of action may extend due to receptor binding.
Primarily fecal excretion of unchanged drug (≥90%) and biliary elimination; renal excretion accounts for <2%.
Primarily renal (65–75% as metabolites), with biliary/fecal excretion accounting for 15–25%.
