Identification
- Summary
Doxercalciferol is a synthetic vitamin D2 analog used to treat secondary hyperparathyroidism in patients with chronic kidney disease with or without therapy of dialysis.
- Brand Names
- Hectorol
- Generic Name
- Doxercalciferol
- DrugBank Accession Number
- DB06410
- Background
Doxercalciferol is a synthetic vitamin D2 analog that undergoes metabolic activation in vivo to form 1α,25-dihydroxyvitamin D2 (1α,25-(OH)2D2), a naturally occurring, biologically active form of vitamin D2. Doxercalciferol is indicated for the treatment of secondary hyperparathyroidism in patients with chronic kidney disease on dialysis, as well as for the treatment of secondary hyperparathyroidism in patients with Stage 3 or Stage 4 chronic kidney disease. Doxercalciferol is marketed under the brand name Hectoral by Genzyme Corporation, and is manufactured by Catalent Pharma Solutions, Inc.

- Mechanism of action
Calcitriol (1α,25-(OH)2D3) and 1α,25-(OH)2D2 regulate blood calcium at levels required for essential body functions. Specifically, the biologically active vitamin D metabolites control the intestinal absorption of dietary calcium, the tubular reabsorption of calcium by the kidney and, in conjunction with parathyroid hormone (PTH), the mobilization of calcium from the skeleton. They act directly on bone cells (osteoblasts) to stimulate skeletal growth, and on the parathyroid glands to suppress PTH (parathyroid hormone) synthesis and secretion. These functions are mediated by the interaction of these biologically active metabolites with specific receptor proteins in the various target tissues. In patients with chronic kidney disease (CKD), deficient production of biologically active vitamin D metabolites (due to lack of or insufficient 25-hydroxyvitamin D-1-alpha-hydroxylase activity) leads to secondary hyperparathyroidism, which contributes to the development of metabolic bone disease.

- Metabolism
Doxercalciferol is absorbed from the gastrointestinal tract and activated by CYP 27 in the liver to form 1α,25-(OH)2D2 (major metabolite) and 1α,24-dihydroxyvitamin D2 (minor metabolite). Activation of doxercalciferol does not require the involvement of the kidneys.

Drug Interaction Integrate drug-drug
interactions in your softwareAcetyldigitoxin The risk or severity of ventricular arrhythmias and Cardiac Arrhythmia can be increased when Doxercalciferol is combined with Acetyldigitoxin. Alfacalcidol The risk or severity of adverse effects can be increased when Alfacalcidol is combined with Doxercalciferol. Aluminum hydroxide The serum concentration of Aluminum hydroxide can be increased when it is combined with Doxercalciferol. Beclomethasone dipropionate The therapeutic efficacy of Doxercalciferol can be decreased when used in combination with Beclomethasone dipropionate. Bendroflumethiazide The risk or severity of hypercalcemia can be increased when Bendroflumethiazide is combined with Doxercalciferol. - Food Interactions
- Avoid antacids. Specifically, avoid magnesium-containing antacids as co-administration with doxercalciferol increases the risk of hypermagnesemia.
