✦ Synopsis

A clinical study was conducted to determine whether, in the topical treatment of psoriasis, a combination of calcipotriol and betamethasone valerate after previous treatment with calcipotriol alone was more effective than the continuation of the monotherapy with calcipotriol, especially in 'low responders'. Patients (n = 169) with the clinical diagnosis 'chronic plaque-type psoriasis' were treated twice daily for 2 weeks with calcipotriol, followed by a 4-week treatment with calcipotriol monotherapy in 87 patients or combined calcipotriol/betamethasone valerate in 82 patients; all patients were followed for 8 weeks. The psoriasis area and severity index (PASI) was used to compare the two treatment groups. The overall therapeutic result was also assessed by the investigators and patients. The combination therapy was more effective, as assessed by all evaluated variables; moreover, patients showing insufficient response to calcipotriol alone after 2 weeks showed a regression of psoriatic lesions using the combination regimen. Thus, the combination of calcipotriol and topical steroids is recommended as the therapy of first choice for patients who do not respond well to treatment with 2 weeks of calcipotriol alone. Furthermore, this combination reduces the hazards associated with the long-term use of topical corticosteroids (atrophy and rebound) as well as the irritation associated with calcipotriol.
