Noncorticosteroid Topical Therapies for the Treatment of Plaque Psoriasis: A Narrative Review

Abstract

Objective: The objective was to compare the safety and efficacy of noncorticosteroid topical treatments for plaque psoriasis. Data Sources: A literature search of the PubMed database was performed (January 1978 to May 2023) using the keywords plaque psoriasis, tapinarof, benvitimod, Vtama, roflumilast, Zoryve, pimecrolimus, tacrolimus, tazarotene, tacalcitol, calcitriol, Vectical, calcipotriene, Dovonex, tacalcitol, vitamin D analogs, salicylic acid, non-corticosteroid topical, Investigator's Global Assessment, and Physician's Global Assessment. Study Selection and Data Extraction: Relevant English-language articles and clinical trial data were considered. Data Synthesis: Six noncorticosteroid topical classes for the treatment of plaque psoriasis were selected. The percentage of patients with plaque psoriasis who achieved Investigator's Global Assessment (IGA) success after 8 weeks of treatment with tacalcitol, calcipotriene/betamethasone dipropionate compound, tazarotene/halobetasol propionate, and roflumilast was 17.9%, 39.9%, 40.7%, and 42.4%, respectively. For 12-week trials of tapinarof and coal tar, 37.4% and 58.2% of patients achieved IGA success, respectively. There were 48% and 71.4% reductions in IGA scores with salicylic acid (12 weeks) and pimecrolimus (4 weeks), respectively. Finally, 66.7% of patients achieved Physician's Global Assessment success with 8 weeks of tacrolimus. There were no serious adverse events for the noncorticosteroid topicals. Conclusion: Noncorticosteroid topicals are suitable options for patients with plaque psoriasis who would like to avoid topical corticosteroids or have experienced adverse effects from chronic corticosteroid use. Due to treatment duration differences and varied outcome measures, it is unclear which noncorticosteroid topical is most efficacious; however, calcineurin inhibitors appear to exhibit the greatest efficacy. Each topical was efficacious in treating plaque psoriasis and had an adequate safety profile. Despite several treatment options for plaque psoriasis, medication adherence is a limiting factor.
