General description

This product is provided as delivered and specified by the issuing Pharmacopoeia. All information provided in support of this product, including SDS and any product information leaflets have been developed and issued under the Authority of the Issuing Pharmacopoeia. For further information and support please go to the website of the issuing Pharmacopoeia.Calcifediol is a biologically active metabolite of vitamin D. It is more hydrophilic and better absorbed in the intestine when compared to ergocalciferol or cholecalciferol due to the high affinity for the vitamin-D-binding protein. The drug is known to treat diseases associated with decreased intestinal absorption and obesity.

Application

Calcifediol EP Reference standard, intended for use in laboratory tests only as specifically prescribed in the European Pharmacopoeia.

Packaging

The product is delivered as supplied by the issuing Pharmacopoeia. For the current unit quantity, please visit the EDQM reference substance catalogue.
