Introduction

Synthetic acetylenic retinoid.1 2 3 4 5 6 7 16 19


Uses for Tazarotene


Psoriasis


Treatment of stable plaque psoriasis with ≤20% body surface area involvement.1 3 4 16 19


Combination therapy with a mid-or high-potency topical corticosteroid more effective than either agent alone.21 22 23


0.1% cream or gel more effective in improving psoriasis manifestations;1 19 0.05% cream or gel associated with less local irritation.1 4 17 19


Acne


Treatment of mild to moderate acne vulgaris.1 6 7 19


Efficacy in patients resistant to oral antibiotics or previously treated with other retinoids not established.1


Photoaging


Palliative therapy to improve dermatologic changes (e.g., fine wrinkling, mottled hypo- or hyperpigmentation, benign lentigines) associated with photodamage.27


Use as an adjunct to a comprehensive skin care plan and sun avoidance program.27 (See Administration under Dosage and Administration.)


Does not eliminate or prevent wrinkles, repair photodamaged skin, reverse photoaging, or restore youthful or younger dermal histologic pattern.27 No mitigating effects on severe manifestations of chronic sunlight exposure (e.g., coarse/deep wrinkling, tactile roughness, telangiectasia, skin laxity, keratinocytic atypia, melanocytic atypia, dermal elastosis) demonstrated.27


Safety and efficacy not established for use in nonwhite (e.g., Asian, Hispanic) patients or Fitzpatrick skin types V and VI.27


Tazarotene Dosage and Administration


General



  • Excessive use does not increase therapeutic effect and may produce marked inflammatory reactions (e.g., erythema, peeling, discomfort).1 19 27 (See Dermatologic Effects under Cautions.)



Administration


Topical Administration


Apply topically to the skin as a cream or gel.1 19 27


For dermatologic use only; avoid contact with mouth, eyes, and other mucous membranes.1 19 27


Wash hands after applying cream or gel (unless the hands are being treated for psoriasis).1 19 27


Occlusive dressings or wrappings should not be used.d e


A transient feeling of pruritus, burning, or stinging may occur after application.1 17 19


If irritation is excessive, temporarily discontinue therapy, reduce dosage strength (in patients with psoriasis), or decrease frequency of applications; reinitiate therapy or increase drug concentration or application frequency when patient is able to tolerate the drug.1 19 27 Closely monitor patient response and tolerance to changes in drug concentration or application frequency.19 27


Psoriasis

Apply a sufficient amount (2 mg/cm2) of cream or gel to cover affected area lightly.1 19


Apply cream or gel to dry skin.1 19 If required, apply moisturizer ≥1 hour prior to applying cream or gel; apply tazarotene only after ensuring that there is no more moisturizer on skin surface.1 19


Avoid application of cream or gel to unaffected skin; these areas may be more susceptible to irritation.1 17 19 (See Dermatologic Effects under Cautions.)


Acne

Gently wash and dry affected area(s) prior to application.1 19


Apply a sufficient amount of 0.1% cream or gel (2 mg/cm2) to cover all lesions with a thin film.1 19


Photoaging

Apply 0.1% cream topically to the face; use the minimum amount necessary to cover the face (including eyelids if desired) lightly; avoid eyes and mouth.27


Gently wash face with mild soap, pat and dry, and wait 20–30 minutes before applying tazarotene cream to face.27


Moisturizers may be applied to skin before or after application of tazarotene; however, allow first topical preparation to absorb into the skin and dry completely before applying the second preparation.27


Administer in conjunction with a comprehensive skin care plan and a sun avoidance program;27 apply a moisturizing sunscreen (≥15 SPF) every morning.27

ActionsActions



  • Pharmacologic actions similar to other retinoids (e.g., vitamin A, tretinoin, isotretinoin); however, tazarotene shows selective affinity for specific nuclear retinoic acid receptor (RAR) proteins RARĪ² and RARĪ³ and may modify gene expression.2 6 7 16 a b c




  • Exact mechanism(s) of action for treatment of psoriasis not determined.1 19 May affect expression of genes that modulate cell (e.g., epidermal) differentiation, proliferation, and inflammation,2 3 5 6 7 16 leading to normalization of keratinocyte differentiation and reduced cellular hyperproliferation and inflammation.16 19 a




  • Exact mechanism(s) of action for treatment of acne not fully understood.1 Appears to modulate follicular keratinization, cell proliferation, and inflammation resulting in inhibition of corneocyte accumulation and cohesion and decreased inflammatory and noninflammatory acne lesions.6 7 19 a




  • Exact mechanism(s) of action in the treatment of photoaging not determined.27 May increase the number of granular cell layers and increase the incidence of epidermal edema.27



Advice to Patients



  • Importance of clinicians instructing patients about proper use of the drug, including associated precautions.1 19 Provide copy of the manufacturer's patient instructions.a b c d e f




  • Importance of women informing clinician if they are or plan to become pregnant or plan to breast-feed.1 19 27 Necessity for clinicians to describe risk of birth defects and to advise women to avoid pregnancy by using adequate methods of contraception during therapy.1 19 27 (See Fetal/Neonatal Morbidity and Mortality under Warnings.)




  • Importance of avoiding excessive use of topical tazarotene.d e f




  • Importance of contacting clinician if dermatologic condition worsens with tazarotene therapy.1 19




  • Importance of avoiding use of shaving lotions, astringents, perfume, toners, peeling (desquamating) agents, permanent wave solutions, electrolysis, hair depilatories, or other preparations or processes that might irritate the skin.1 17 19 27




  • Importance of consulting clinician regarding specific instructions for routine skin care, use of cosmetics, moisturizers, and sunscreens.27 c




  • Importance of adhering to prescribed directions for use; avoid contact with eyes, mouth, or mucous membranes.1 19 27




  • Importance of informing patients that treated areas of the skin should not be bandaged or otherwise covered or wrapped so as to be occlusive unless directed by their clinician.d e




  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and cosmetic products or procedures.a b c




  • Importance of informing patients of other important precautionary information. (See Cautions.)
