Calcipotriol (INN) or calcipotriene (USAN) is a synthetic derivative of calcitriol, a form of vitamin D. It is used in the treatment of psoriasis, marketed under the trade name "Dovonex" in the United States, "Daivonex" outside of North America, and "Psorcutan" in Germany. This medication is safe for long-term application in psoriatic skin conditions.
- Very common (> 10% frequency)
- Skin irritation
- Common (1–10% frequency)
- Uncommon (0.1–1% frequency)
- Exacerbation of psoriasis
- Rare (< 0.1% frequency)
Cautions include exposure to excessive natural or artificial light, due to the potential for calcipotriol to cause photosensitivity.
No drug interactions are known.
The efficacy of calcipotriol in the treatment of psoriasis was first noticed by the observation of patients receiving various forms of vitamin D in an osteoporosis study. Unexpectedly, some patients who also suffered from psoriasis experienced dramatic reductions in lesion counts.
The precise mechanism of calcipotriol in remitting psoriasis is not well understood. However, it has been shown to have comparable affinity with calcitriol for the vitamin D receptor (VDR), while being less than 1% as active as the calcitriol in regulating calcium metabolism. The vitamin D receptor belongs to the steroid/thyroid receptor superfamily, and is found on the cells of many different tissues including the thyroid, bone, kidney, and T cells of the immune system. T cells are known to play a role in psoriasis, and it is thought that the binding of calcipotriol to the VDR modulates the T cells gene transcription of cell differentiation and proliferation related genes.
