Mechanism of action

Inecalcitol is an analogue of calcitriol, the naturally active metabolite of vitamin D. Calcitriol and their analogues activate the vitamin D receptor (VDR). Vitamin D has a major role in regulating calcium absorption from the gut, storage in mineral form in the bones, and excretion by the kidney and effectively prevents rickets in infants. Vitamin D and calcitriol can cause hypercalcemia at high or frequently repeated doses; in turn, hypercalcemia can cause kidney toxicity by accumulation of calcium-containing micro-crystals and heart and muscle dysfunction by impairing contractions. [Hybrigenics Website] The mechanism of action is currently unknown, but it is proposed that inecalcitol exerts its superagonistic action through enhancing coactivator binding by the VDR.
