Allgemeine Beschreibung

1α-Hydroxyvitamin D3, also known as alfacalcidol, is a synthetic vitamin D3 analogue, hydroxylated in position one. It is metabolized to 1,25-dihydroxycholecalciferol by 25-hydroxylases.

Biochem./physiol. Wirkung

1α-Hydroxyvitamin D3 facilitates calcium absorption and deposition. It also has an ability to inhibit bone resorption and stimulate bone formation. Alfacalcidol is used for treating various bone diseases such as rickets/osteomalacia, renal osteodystrophy and osteoporosis. It acts as a chemopreventive agent and reduces the risk colitis and carcinogenesis.
