Tazarotene
Résumé
Tazarotene, sold under the brand name Tazorac, among others, is a third-generation prescription topical retinoid. It is primarily used for the treatment of plaque psoriasis and acne. Tazarotene is also used as a therapeutic for photoaged and photodamaged skin. Tazarotene is a member of the acetylenic class of retinoids.
It is available as a generic medication.
Tazarotene is most commonly used topically to treat acne vulgaris and psoriasis. Like other topical retinoids, such as tretinoin and adapalene, tazarotene can be combined with benzoyl peroxide or an oral antibiotic, such as clindamycin or dapsone, for the treatment of acne. This results in increased efficacy compared to tazarotene monotherapy. For psoriasis, a combination therapy of tazarotene and a mid- to high-potency corticosteroid is more effective than either treatment alone.
Tazarotene can also be used for the treatment of photodamaged skin. It can reduce the clinical and histological signs of photodamaged skin. The therapy is more effective when used with the daily application of sunscreen.
Before 2015, tazarotene was considered a Category X drug (meaning its use was contraindicated during pregnancy) according to Food and Drug Administration (FDA) guidelines, despite demonstrating similar plasma retinoid levels as adapalene and tretinoin, which were classified as Category C drugs. Under the FDA's updated Pregnancy and Lactation Labeling Rule which eliminated the lettered pregnancy categories and came into effect in 2015, tazarotene was determined to be contraindicated in pregnancy. Because of the lack of pregnancy outcomes data for the drug, the determination was based on the teratogenic effects observed in rat and rabbit studies.
Tazarotene is contraindicated for use in patients who are known to be or suspected of being pregnant. Tazarotene is a known teratogen. It is also contraindicated in patients with a known hypersensitivity to any ingredient in the specific pharmaceutical formulation.
Adverse effects for tazarotene include skin irritation, such as redness, itchiness, and burning.
