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.

The 'classical' effects of vitamin D receptor activator or agonist (VDRA) therapy for the treatment of secondary hyperparathyroidism in patients with chronic kidney disease primarily involves suppressive effects on the parathyroid gland, and regulation of calcium and phosphorus absorption in
