Vitamin D analogues
(Redirected from Vitamin D analogue)
The natural, active form of vitamin D is calcitriol (1,25-dihydroxycholecalciferol). This molecule and other naturally occurring forms of vitamin D, including its precursors and metabolites, have been modified to synthesize pharmaceuticals with potentially greater, or selective, therapeutic actions.[1][2][3][4]
Types
[edit]These include:
- Alfacalcidol
- Calcipotriol (calcipotriene)
- Doxercalciferol
- Falecalcitriol
- Paricalcitol
- Tacalcitol
Mechanisms
[edit]These modified vitamin D analogues have a side chain or other modifications. They aim to reduce the classical renal and intestinal effects of calcitriol on calcium and phosphate homeostasis, from its effects on other biologic processes.[5] They target cell proliferation and differentiation, especially in skin, or other effects in the parathyroid gland (secondary hyperparathyroidism) or bone cells.[5]
