title: Progress in self treatment for psoriasis vulgaris.
abstract: Chronic plaque psoriasis is by far the most frequent form of the disease and is usually amenable to home treatment. The therapeutic armamentarium for self-treatment of psoriasis has, until recently, been limited to emollients, tar, dithranol and topical corticosteroids. Although limited progress has been made in improving formulations and treatment regimes for these compounds, they still have significant drawbacks in terms of either unwanted effects or cosmetic acceptability. Topical vitamin D analogues offer a new, effective, convenient and safe option for self-treatment of psoriasis. Most research has been performed on calcipotriol. This has compared well to beta-methasone valerate and short-contact dithranol in controlled studies. Skin irritation is frequently noticed by patients, but rarely requires treatment to be discontinued. The mechanism of action appears most likely to be a direct regulation of keratinocyte proliferation and differentiation. Calcipotriol has relatively little effect on calcium metabolism and appears to be safe when used according to established guidelines but hypercalcaemia may develop if excessive quantities are used.
