CALCIFEDIOL(Cas 19356-17-3) Usage

Description

Calcifediol (synonym 25-Hydroxyvitamin D3) is a vitamin D analog and the major metabolite of vitamin D3 (Cholecalciferol) in the liver. Its main function is the regulation of calcium and phosphorus, which is necessary for strong bones. It is used to treat patients with serious kidney diseases to decrease the parathyroid hormone (PTH) level. It is used to treat rickets and osteomalacia, both in azotemic and non-azotemic patient. Calcifediol is sold under RAYALDEE? to treat secondary hyperparathyroidism associated with vitamin D insufficiency in stage 3-4 chronic kidney disease.

Uses

Calcidiol is the precursor to vitamin D3, a steroid hormone that helps regulate calcium and phosphorus levels in the body, mineralizes bones, and assimilates vitamin A. Calcidiol is fat-soluble and helps with bone and teeth growth and development. It can be used as a stable isotope internal standard for data interpretation in specific biological samples by mass spectrometry.

Advantages of the use of calcidiol derive from the pharmacokinetic properties and are related to the possibility of use in patients with liver disease, obese patients, patients with intestinal malabsorption, secondary hyperparathyroidism associated with chronic kidney disease as well as to avoid any possible toxic effect when high doses are used.

Vitamin D3 and calcidiol are not equipotent

Cristina Navarro-Valverde a, Manuel Sosa-Henríquez b, Maria Rosa Alhambra-Expósito c, José Manuel Quesada-Gómez c

, The Journal of Steroid Biochemistry and Molecular Biology Volume 164, November 2016, Pages 205-208

In Spain, the use of calcidiol (25(OH)D3) at the same dose than Vitamin D3 is the most extended prescription, notwithstanding the available evidence stating that they are not equipotent. This may lead to over-dosage.
