Off-label uses of TNF-α inhibitors and IL-12/23 inhibitors in dermatology

Abstract

TNFα inhibitors, which include adalimumab, infliximab, etanercept, certolizumab, and golimumab, and IL12/23 inhibitor, ustekinumab, have been widely used as a U.S. Food and Drug Administration (FDA) approved for the treatment of psoriasis. Outside of psoriasis, high levels of TNFα had also been found in several skin diseases including hidradenitis suppurativa. IL12 and IL23 play important role in the pathogenesis of SLE, alopecia areata, and vitiligo. This paper reviews the off-label uses of TNFα inhibitors and IL12/23 inhibitors in skin disorders.
