Water-in-oil emollients as steroid-sparing adjunctive therapy in the treatment of psoriasis

An open label study of ninety-six patients with chronic plaque-type psoriasis demonstrated the efficacy of the addition of water-in-oil emollients to a topical corticosteroid regimen. Twice daily application of betamethasone dipropionate cream and once daily application of both betamethasone dipropionate cream and either a water-in-oil based moisturizing cream or lotion were equivalent in efficacy (p = 0.05). Once daily application of both betamethasone dipropionate cream and either a water-in-oil based cream or lotion was significantly better than once daily application of betamethasone dipropionate cream alone (p = 0.05). Water-in-oil emollients are useful in the therapy of chronic, plaque-type psoriasis and provide a steroid-sparing effect.
