Full Prescribing Info
Action
Alfacalcidol or 1-α-hydroxyvitamin D3 is one of vitamin D analogue. Alfacalcidol is rapidly converted in liver to 1, 25-dihydroxyvitamin D3 {1, 25-(OH)2D3}, the metabolite of vitamin D3 which acts as a regulator of calcium and phosphate metabolism.
Impaired endogenous production of 1, 25-dihydroxyvitamin D3 by the kidneys appears to contribute to the disturbances in mineral metabolism found in several disorders, including renal bone disease hypoparathyroidism and vitamin D-dependent rickets. These disorders require high doses of vitamin D for their correction.
