Description
Curator's Comment: Description was created based on several sources, including https://www.accessdata.fda.gov/drugsatfda_docs/label/2011/020600s008lbl.pdf

Tazarotene a novel acetylenic retinoid is known to be effective in the topical treatment of psoriasis and acne. Tazarotene is rapidly and completely metabolized to its active metabolite tazarotenic acid. The exact mechanism of action of tazarotenic acid in the treatment of psoriasis and acne is not clearly defined. However, it is thought that the selective interaction of tazarotenic acid with the retinoic acid receptor (RAR) family (RARα, RARβ, and RARγ) and the subsequent induction of both positive and negative gene regulatory effects may be involved.

Sample Use Guides

For psoriasis: It is recommended that treatment start with TAZORAC (Tazarotene) 0.05% Gel, with strength increased to 0.1% if tolerated and medically indicated. Apply TAZORAC® Gel once a day, in the evening, to psoriatic lesions, using enough (2 mg/cm2) to cover only the lesion with a thin film to no more than 20% of body surface area. If a bath or shower is taken prior to application, the skin should be dry before applying the gel. If emollients are used, they should be applied at least an hour before application of TAZORAC® Gel.
Route of Administration: Topical
Tazarotene treatment caused a dose-dependent reduction in cell proliferation in BCC cell line ASZ001 cells (the strongest effect on cell proliferation was at 10 umol/L)
