Abstract
Background: In extensive psoriasis, topical corticosteroids are generally only used to supplement phototherapy and systemic therapy. Spray formulations are easier than other vehicle preparations to apply and may be an option for treating extensive psoriasis.
Objective: To evaluate the potential for hypothalamic–pituitary–adrenal axis suppression and efficacy of topical desoximetasone 0.25% spray formulation in patients with extensive psoriasis.
Methods: A multicenter, open label, nonrandomized, clinical trial was conducted. Two groups of 12 adults with moderate to severe plaque-type psoriasis were treated with 0.25% desoximetasone spray for 28 days. Physician global assessment (PGA) and body surface area (BSA) were assessed. Cortisol-induced suppression test was performed at baseline, day 14 and day 28 to assess safety.
Results: No statistically significant difference was seen in adrenal suppression; odds ratio of 0.779 (p = .85). The mean PGA improvement from baseline was 1.83 and 1.33 for moderate and severe psoriasis, respectively. Mean BSA involvement at baseline for moderate and severe psoriasis was 11% and 23%, respectively, improving to 5% and 19%, respectively.
Conclusions: Considerable improvement can be achieved with short-term potent topical corticosteroid treatment even in patients with severe, extensive psoriasis. For such use, topical desoximetasone has less risk of HPA-suppression than does topical clobetasol.
