Topical calcipotriol/betamethasone dipropionate for psoriasis vulgaris: A systematic review.

Topical calcipotriol/betamethasone dipropionate ointment/gel has been commonly used for the treatment of psoriasis vulgaris. However, the efficacy of this combination needs to be consolidated. We aimed to assess the effects and safety profile of calcipotriol/betamethasone dipropionate for the treatment of psoriasis vulgaris, using evidence based approach. Randomized controlled trials on the treatment of psoriasis vulgaris with calcipotriol/betamethasone dipropionate were identified by searching PubMed, China National Knowledge Infrastructure and the Cochrane Library. The primary outcome measure was the Psoriasis Area and Severity Index (PASI) score. Ten randomized controlled trials involving 6590 participants were included. The methodologies of the studies were generally of moderate to high quality. These trials used topical calcipotriol/betamethasone dipropionate for 4 or 8 weeks, and were compared with topical calcipotriol or betamethasone. The results showed that calcipotriol/betamethasone dipropionate was more effective than controls. A four-week treatment with calcipotriol/betamethasone dipropionate did not show any significant difference between the once-daily or twice-daily regimen. The adverse events of calcipotriol/betamethasone dipropionate were tolerable and acceptable. The reports included in this review are heterogenous and have limitations. Topical application of calcipotriol/betamethasone dipropionate once daily is an efficacious treatment for psoriasis vulgaris and is associated with few side effects.
