Impact of clobetasol propionate 0.05% spray on health-related quality of life in patients with plaque psoriasis.

Psoriasis causes significant distress and impairment in health-related quality of life (QOL) in afflicted patients. For this reason, QOL is an essential and important measure of treatment outcome in patients with the disease. Clobetasol propionate is a super-highpotent class I topical corticosteroid. The spray formulation is approved for twice-daily use for up to 4 weeks by patients 18 years and older with moderate to severe plaque psoriasis. Data collected from 2,236 patients enrolled in 5 clinical trials demonstrate consistent improvement in QOL measures using multiple instruments. In a randomized, double-blind trial in patients with scalp psoriasis, treatment with clobetasol propionate 0.05% spray produced significantly greater improvement in QOL compared with vehicle, as measured by the Scalpdex QOL instrument. In another randomized trial in patients with moderate to severe plaque psoriasis, clobetasol propionate 0.05% spray produced significantly greater reductions in mean affected body surface area and significantly greater improvements in QOL, as measured by the Dermatology Life Quality Index (DLQI), compared with a 0.05% foam formulation. When compared with calcipotriene/betamethasone dipropionate ointment, clobetasol propionate 0.05% spray produced greater rates of lesion clearance and similar improvement in QOL scores after 2 or 4 weeks of treatment. When clobetasol propionate 0.05% spray was used as monotherapy or as an add-on therapy for 4 weeks in a large, observational trial, approximately 80% of patients experienced consistent and significant improvement in QOL on 2 separate, validated QOL instruments (DLQI and the Koo-Menter Psoriasis Index). In conclusion, clobetasol propionate 0.05% spray is an efficacious and safe treatment for plaque psoriasis and produces significant improvement in QOL for affected patients.
