Two phase 3 clinical trials of tazarotene lotion 0.045% (Arazlo, Ortho Dermatologics) suggest the topical could be helpful for the treatment of moderate-to-severe acne vulgaris, according to results published in the January issue of the Journal of Drugs in Dermatology.
The topical, which was approved in December 2019 by the U.S. Food and Drug Administration (FDA), is the first approved tazarotene in lotion form for the treatment of acne vulgaris in patients nine years of age and older.
While tazarotene 0.1% gel, foam and cream has been proven to be an efficient treatment for acne, as with many retinoids, it’s also been found to cause irritation such as dryness, scaling, burning, erythema and pruritus, which can limit its usefulness.
To examine the safety, tolerability and efficacy of tazarotene in lotion form, both studies utilized polymetric emulsion technology, which employs a constant disbursement of humectants, moisturizing ingredients and active ingredients contained in micronized oil droplets to aid in the distribution into the epidermis. This lead to an increased tolerability while maintaining parallel efficacy to other vehicle formulations such as gels and foams.
During the double-blind, parallel, randomized, multicenter and placebo-controlled trials, 1,600 patients were randomized to receive either tazarotene 0.045% lotion or vehicle over 12 weeks.
