Tapinarof: a felicitous discovery in psoriasis treatment - Vol.13(3), Sep - New Delhi SAGE 2022 - 222-228p.
Tapinarof is a novel topical formulation approved recently, in May 2022, by the United States Food and Drug Administration to treat plaque psoriasis. Existing topical therapies for psoriasis are limited by systemic and local adverse effects, medication cost and repeated administration, thus significantly hampering the compliance of patients to therapy. These limitations can be resolved by tapinarof owing to its better efficacy and favourable safety profile in psoriasis management. Tapinarof was developed with a unique mechanism targeting the aryl hydrocarbon receptor (AhR) involved in inflammation and modulation of skin barrier integrity in inflammatory dermatological disorders such as psoriasis and atopic dermatitis. The efficacy and safety outcomes of tapinarof in psoriasis were justified through the two pivotal clinical trials, namely, PSOARING 1 and PSOARING 2. The common adverse effects observed with tapinarof are folliculitis, contact dermatitis and headache. The literature search was conducted for efficacy and safety of tapinarof in the electronic databases of PubMed and Cochrane using a combination of keywords such as tapinarof, psoriasis and AhR. This review will delineate the molecular mechanisms underlying the action of tapinarof and also summarise the trial data supporting the claim that tapinarof is replacing the existing standard of care in psoriasis management.
