Tacalcitol is a vitamin D3 analog that functions as a potent agonist of the vitamin D receptor. It exerts its mechanism of action by binding to the vitamin D receptor in target cells, leading to the regulation of gene expression involved in cellular differentiation and proliferation. Tacalcitol modulates the immune response by inhibiting the production of pro-inflammatory cytokines and promoting the production of anti-inflammatory cytokines. Tacalcitol also plays a role in the regulation of calcium and phosphate metabolism by enhancing the absorption of calcium in the intestines and promoting its reabsorption in the kidneys. Tacalcitol may inhibit the proliferation of keratinocytes and promote their differentiation.
