Beschreibung

General description

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 Actions

Synthetisches Vitamin D₃-Aanalogon, das zu 1,25-Dihydroxycholecalciferol verstoffwechselt wird. Hemmt die Knochenresorption und stimuliert die Knochenbildung. Unterdrückt Parathormon-Sekretion durch Rindemebenschilddrüsenzellen.

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.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
