Topical long-term therapy of psoriasis with vitamin D₃ analogues, corticosteroids and their two compound formulations: position paper on evidence and use in daily practice

BACKGROUND: Current data from daily practice show that vitamin D₃ analogues, corticosteroids and their fixed combination products are used heterogeneously for topical long-term treatment of psoriasis.

AIM: To evaluate scientific evidence about topical long-term therapy with vitamin D3 analogues, corticosteroids and their two-compound-products in psoriasis vulgaris and scalp psoriasis and to develop daily practice recommendations.

METHODS: Systematic literature review via PubMed and Embase and informal expert consensus.

RESULTS: The search strategy identified 21 relevant clinical trials. Best evidence regarding topical long term treatment was available for the two-compound-formulation containing calcipotriene and betamethasone. In a comparative trial in psoriasis vulgaris the two-compound-formulation showed superior tolerability and cost effectiveness compared to monotherapy. In scalp psoriasis the two-compound-gel was superior compared to calcipotriene monotherapy. Standardized and simplified treatment application modes resulted in a better clinical outcome comparing to on-demand therapies.

DAILY PRACTICE RECOMMENDATIONS: Patients should be proactively involved in the choice of treatment, formulation and mode of application. Besides long-term treatment with the two-compound-formulation other treatment regimens including calcipotriene monotherapy can also be considered. Due to a favorable risk-benefit ratio in maintenance trials and due to better cost-effectiveness the application of two-compound-products once or twice a week after initial therapy is recommended.
