Biochem/physiol Actions:	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.
Biochem/physiol Actions:	Synthetic vitamin D₃ analog that is metabolized to 1,25-dihydroxycholecalciferol. Inhibits bone resorption and stimulates bone formation. Supresses parathyroid hormone secretion by bovine parathyroid cells.
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.
Packaging:	Bottomless glass bottle. Contents are inside inserted fused cone.
