Also provided is a topical combination composition comprising from about 0.25% w/w to about 2.0% w/w tapinarof, from about 0.025% w/w to about 0.1% w/w w tazarotene, from about 0.01% w/w to about 0.25% w/w at least one corticosteroid of potency class 1-4 and a carrier suitable for topical administration. The above compositions are useful for the treatment, prevention or alleviation of plaque psoriasis and exhibit synergistic and/or additive effects which allow reducing the amounts of the active agents in the compositions. The addition of tazarotene to tapinarof potentiates the tapinarof anti-psoriatic therapeutic effect. |
