Alfacalcidol (1α-hydroxycholecalciferol) is a synthetic vitamin D compound hydroxylated in position one. It is different from calcitriol in that it has not been hydroxylated at position 25, but this conversion takes place rapidly in the liver following oral or parenteral administration of alfacalcidol in humans [203].

Due to strong feedback regulation, plain vitamin D is not activated in the kidney in vitamin-replete patients, while alfacalcidol, having been hydroxylated at position 1, bypasses regulation and increases available amounts of active D-hormone in different target tissues.

What is the difference between alfacalcidol and calcitriol?

There is only one short-term study which directly compares these two drugs. This study demonstrates that calcitriol is superior to alfacalcidol. However, alfacalcidol is a prohormone of calcitriol. It has to be converted by 25-hydroxylase at the liver to generate 1,25-dihydroxyvitamin D3 to act on target cells.

Why is alfacalcidol given?

Although alfacalcidol is widely used in the treatment of osteoporosis, its mechanism of action in bone is not fully understood. Alfacalcidol stimulates intestinal calcium (Ca) absorption, increases urinary Ca excretion and serum Ca levels, and suppresses parathyroid hormone (PTH) secretion.
