Biochem/physiol Actions

Tacalcitol is widely used in the treatment of dermatosis due to its ability to inhibit keratinocyte proliferation and induce cell differentiation. It also has anti-inflammatory activity and has been shown to reduce cutaneous inflammation via suppression of leukocyte infiltration in skin. Tacalcitol is topically used for the treatment of psoriasis and has also been found to be effective in the treatment of acquired perforating collagenosis (APC), a rare perforating dermatosis. Studies suggest that this compound has potential for the treatment of the hereditary disorder Hailey-Hailey Disease.
