Description

Biochem/physiol Actions

Doxercalciferol is a Vitamin D2 analogue, a Vitamin D Receptor Activator (VDRA). Doxercalciferol acts as a pro-hormone, needing 25-hydroxylation in the liver for bioactivation into 1α, 25-hydroxyvitamin D2. Pivotal studies in adults on dialysis have demonstrated control of secondary hyperparathyroidism that is superior to placebo therapy, without undue suppression of 1st IMA-PTH < 300 pg/mL, or occurrences of hypercalcemia. Doxercalciferol has been shown to be effective in controlling secondary hyperparathyroidism of adult patients with CKD stages 3-4.

Doxercalciferol is a vitamin D₂ analog that acts as a pro-hormone, activated in the liver to 1α,25-dihydroxyvitamin D₂. Despite its relatively low affinity for the vitamin D receptor (VDR) (before activation), it is effective at suppressing expression of the parathyroid hormone (PTH) gene, and appears to act through the VDR.
