Psoriasis affects 2-4% of the population worldwide and its treatment is currently far from satisfactory. Calcipotriol and Portulaca oleracea have been reported to exhibit the capacity to inhibit inflammation in psoriatic patients and improve their clinical condition. However, the efficacy of a combination regimen of these two components remains unknown. The aim of the present study was to explo...

The efficacy and safety of 0.3% tacrolimus gel and 0.5% tacrolimus cream compared with calcipotriol ointment were evaluated in adults (n = 124) with mild to moderate plaque psoriasis. Treatment was twice daily for a maximum of 12 weeks. Clinical efficacy was assessed by the percentage change in the local psoriasis severity index of a target lesion between baseline and week 12. By week 12, the m...

Background One of the advances in the treatment of plaque-type psoriasis is combined local therapy with calcipotriol and betamethasone. To provide both ingredients in a two-compound product, efforts have been made to unite calcipotriol and betamethasone because they are usually inactivated when present in the same formulation. This aspect was resolved when carefully designed vehicle components ...

Vitamin D3 reduces human rectal crypt cell production rate (CCPR) and may thereby protect against colorectal cancer. Cell turnover is increased in ulcerative proctocolitis, which might therefore respond to vitamin D3 metabolites. This study investigated the effect of calcipotriol, a synthetic vitamin D3 analogue that avoids hypercalcaemia, on human rectal CCPR in ulcerative proctocolitis. Paire...

OBJECTIVE Psoriasis is a chronic inflammatory skin disease and topical therapy remains a key role for treatment. The aim of this study is to evaluate the influence of psoriasis-like lesions on the cutaneous permeation of anti-psoriatic drugs. METHODS We first set up imiquimod-induced dermatitis in mice that closely resembles human psoriasis lesions. The development of the lesions is based on ...

Although only a small area of the body is affected in palmoplantar psoriasis or psoriasis of the palms and soles, this condition causes considerable functional impairment due to hyperkeratosis, fissures, and erythema, and occasionally inflammation and pustules. These symptoms may seriously interfere with the patient’s quality of life and may be disabling. Moreover, the lack of a standard treatm...

To investigate if there is a synergy between the presence of the Malassezia yeasts and the adverse reaction during treatment of scalp psoriasis with calcipotriol scalp solution, patients were treated with itraconazole to reduce the number of Malassezia yeasts. This study was a double-blind, placebo-controlled parallel group study between oral itraconazole or placebo for 8 weeks in patients with...
