Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/4310770

Calcifediol (25-Hydroxyvitamin D3 or 25-hydroxycholecalciferol) is a biologically active vitamin D3 metabolite. It is concluded that the liver is the major if not the only physiologic site of hydroxylation of vitamin D3 into calcifediol. Calcifediol is a prohormone of the active form of vitamin D3, calcitriol (1,25-dihydroxyvitamin D3). Calcifediol is converted to calcitriol by cytochrome P450 27B1 (CYP27B1), also called 1-alpha hydroxylase, primarily in the kidney. Calcitriol binds to the vitamin D receptor in target tissues and activates vitamin D responsive pathways that result in increased intestinal absorption of calcium and phosphorus and reduced parathyroid hormone synthesis. RAYALDEE (calcifediol) extended-release capsules is indicated for the treatment of secondary hyperparathyroidism in adult patients with stage 3 or 4 chronic kidney disease.

Sample Use Guides

In Vivo Use Guide

The initial dose of RAYALDEE (calcifediol) extended-release capsules is 30 mcg administered orally once daily at bedtime. Serum calcium should be below 9.8 mg/dL before initiating treatment. Monitor serum calcium, phosphorus, 25-hydroxyvitamin D and intact parathyroid hormone (PTH) 3 months after starting therapy or changing dose. Increase the dose to 60 mcg once daily after 3 months if intact PTH is above the treatment goal. Ensure serum calcium is below 9.8 mg/dL, phosphorus is below 5.5 mg/dL and 25-hydroxyvitamin D is below 100 ng/mL before increasing the dose. Suspend dosing if intact PTH is persistently abnormally low, serum calcium is consistently above the normal range or serum 25 hydroxyvitamin D is consistently above 100 ng/mL

Route of Administration: Oral

In Vitro Use Guide

Vitamin D metabolites down-regulated stimulated IL-8 only in those hyperinflammatory monocyte-derived macrophages, and only when used at high doses (>100 nM for Calcifediol).
