PHARMACOLOGY Alfacalcidol is fat soluble and upto 100% absorption normally takes place. After absorption,
alfacalcidol is rapidly hydroxylated at 2 position, predominantly in liver although the enzyme is
widely distributed in body tissues.1 Alfacalcidol (1-hydroxyvitamin D3) undergoes rapid hepatic
conversion to 1,25-dihydroxyvitamin D3, which acts as a regulator of calcium and phosphate
metabolism. Due to this rapid conversion, the therapeutic benefits of alfacalcidol are virtually the
same as those of 1,25-dihydroxyvitamin D3.
2 The main effects are to increase circulating 1,25-
dihydroxyvitamin D3 levels, and thereby to increase intestinal absorption of calcium and
phosphate, promote bone mineralisation, regulate plasma parathyroid hormone levels as well as
to decrease bone resorption, with relief of bone and muscle pain.
