ADAPALENE vs FABIOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Retinoic acid receptor agonist; binds to RARβ/γ nuclear receptors, modulating gene expression to normalize follicular keratinization and reduce comedogenesis.
Retinoid that binds to retinoic acid receptors (RARs) and retinoid X receptors (RXRs), inducing differentiation and apoptosis of keratinocytes.
Apply a pea-sized amount topically to affected areas once daily in the evening.
FABIOR (tazarotene) foam, 0.1%: Apply a thin layer once daily in the evening to affected areas of the face, scalp, or trunk.

The terminal elimination half-life of adapalene after topical application is approximately 17 hours (range 7–51 hours), reflecting slow release from skin depot and hepatic clearance. This supports once-daily dosing.
Clinical Note
moderateAdapalene + Gatifloxacin
"Adapalene may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateAdapalene + Rosoxacin
"Adapalene may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateAdapalene + Levofloxacin
"Adapalene may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateAdapalene + Trovafloxacin
"Adapalene may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life is approximately 24-26 hours, supporting once-daily dosing.
Adapalene is eliminated primarily via biliary excretion into feces. After oral administration in animals, approximately 80% of the dose is recovered in feces and about 10% in urine; for topical application, systemic absorption is minimal and the small absorbed fraction undergoes similar hepatobiliary elimination.
Primarily hepatic metabolism via CYP450; renal excretion of metabolites accounts for <1% of dose as unchanged drug. Fecal elimination is the major route (approximately 90%).
