Talcalcitol is a synthetic analogue of vitamin D3. Tacalcitol has been developed by Teijin in Japan with the aim of maintaining the potent cell-regulating properties of calcitriol without the calcium-related adverse effects. Tacalcitol differs structurally from calcitriol by hydroxylation in the 24 position instead of the 25 position. Tacalcitol can influence the principal pathogenetic factors of psoriasis by inducing normalisation of keratinocyte differentiation, performing an anti-proliferative action and finally modulating the inflammatory response. Tacalcitol has been launched as an ointment formulation for the treatment of psoriasis in various countries. High-dose formulations (ointment and lotion) are available in Japan.
