Coal tar 2% foam in combination with a superpotent corticosteroid foam for plaque psoriasis: case report and clinical implications.
Psoriasis is a chronic, inflammatory, immune-mediated, multi-system disease that is treated with a variety of medicines, including topical corticosteroids and, historically, coal tar. In this case, the authors evaluated whether combination therapy with coal tar foam 2% and a topical corticosteroid would induce a remission and maintain clearance of plaque-type psoriasis over an eight-week period. A 59-year-old Caucasian woman with plaque psoriasis of her elbows presented to the authors' dermatology clinic and was treated with clobetasol propionate 0.05% emollient foam in combination with coal tar 2% foam twice daily to her elbows for two weeks. After two weeks, the patient was switched to a maintenance regimen of twice-daily coal tar 2% foam during the week and twice-daily application of the corticosteroid on the weekends. The patient exhibited very favorable clearance of her plaque psoriasis on this regimen at her eight-week follow-up visit. In this case, the combination of coal tar 2% foam and clobetasol propionate 0.05% emollient foam twice daily was used effectively to induce remission of localized plaque psoriasis followed by an efficacious maintenance regimen, which incorporated intermittent therapy with both topical agents.
