PRESCRIPTION DRUG
TAZORAC® (tazarotene) Gel 0.05% and 0.1% are indicated for the topical treatment of patients with stable plaque psoriasis of up to 20% body surface area involvement. TAZORAC® (tazarotene) Gel 0.1% is also indicated for the topical treatment of patients with facial acne vulgaris of mild to moderate severity. The efficacy of TAZORAC® Gel in the treatment of acne previously treated with other retinoids or resistant to oral antibiotics has not been established. Retinoids may cause fetal harm when administered to a pregnant woman. In rats, tazarotene 0.05% gel, administered topically during gestation days 6 through 17 at 0.25 mg/kg/day (1.5 mg/m2 /day) resulted in reduced fetal body weights and reduced skeletal ossification. Rabbits dosed topically with 0.25 mg/kg/day (2.75 mg/m2 total body surface area/day) tazarotene gel during gestation days 6 through 18 were noted with single incidences of known retinoid malformations, including spina bifida, hydrocephaly, and heart anomalies. Systemic daily
TAZORAC® (tazarotene) Gel is available in concentration of 0.1%. It is available in a collapsible aluminum tube with a tamper-evident aluminum membrane over the opening and a white propylene screw cap, in 30 gm and 100 gm sizes. NOTE: TAZORAC® (tazarotene) Gel should be stored at 25°C (77°F): excursion permitted to 15-30°C (59-86°F). RX ONLY ® Marks owned by Allergan, Inc.

New Drug Application
TAZORAC - TAZAROTENE GEL PHYSICIANS TOTAL CARE, INC. ---------- FOR DERMATOLOGIC USE ONLY NOT FOR OPHTHALMIC, ORAL OR INTRAVAGINAL USE DESCRIPTION TAZORAC Gel is a translucent, aqueous gel and contains the compound tazarotene, a member of the acetylenic class of retinoids. It is for topical dermatologic use only. The active ingredient is represented by the following structural formula: CHEMICAL NAME: Ethyl 6-[2-(4,4-dimethylthiochroman-6-yl) ethynyl] nicotinate CONTAINS : ACTIVE: Tazarotene................................... 0.05% or 0.1% (w/w) PRESERVATIVE: Benzyl alcohol.................................. 1.0% (w/w) INACTIVES: Ascorbic acid, butylated hydroxyanisole, butylated hydroxytoluene, carbomer 934P, edetate disodium, hexylene glycol, poloxamer 407, polyethylene glycol 400, polysorbate 40, purified water, and tromethamine. CLINICAL PHARMACOLOGY Tazarotene is a retinoid prodrug which is converted to its active form, the cognate carboxylic acid of tazarotene (AGN 190299), by rapid deesterification in animals and man. AGN 190299 (“tazarotenic acid”) binds to all three members of the retinoic acid receptor (RAR) family: RARα, RARβ, and RARγ but shows relative selectivity for RARβ, and RARγ and may modify gene expression. The clinical significance of these findings is unknown. PSORIASIS: The mechanism of tazarotene action in psoriasis is not defined. Topical tazarotene blocks induction of mouse epidermal ornithine decarboxylase (ODC) activity, which is associated with cell proliferation and hyperplasia. In cell culture and _in vitro_ models of skin, tazarotene suppresses expression of MRP8, a marker of inflammation present in the epidermis of psoriasis patients at high levels. In human keratinocyte cultures, it inhibits cornified envelope formation, whose build-up is an element of the psoriatic scale. Tazarotene also induces the expression of a gene which may be a growth suppressor in human keratinocytes and which may inhibit epidermal hyperproliferation in treated plaques.
