ARAZLO vs HC #1
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.
