Tacalcitol (1,24-dihydroxyvitamin D3) is a synthetic vitamin D3 analog.[1] Tacalcitol is marketed under several names, including Curatoderm and Bonalfa.

It is on the World Health Organization's List of Essential Medicines.[2]


Tacalcitol reduces excessive cell turnover in the epidermis by interacting with vitamin D receptors on keratinocytes.[3][4]


It is usually prescribed by a general practitioner or dermatologist for the treatment of psoriasis, chronic chapped lips and other severe dry skin conditions because of its ability to reduce excessive skin cell turnover.[1] It is available as an ointment or lotion.

It has also been used for vitiligo[5][6] and Hailey-Hailey disease.[7]
