Alfacalcidol is a widely used vitamin D compound, especially in clinical nephrology because it does not require
enzymatic activation by the kidneys. For that reason it has been used for decades to treat abnormalities in bone and mineral
balance that arise in chronic kidney disease. In this review an overview is provided of available experimental and
clinical data that form the basis of its widespread use. Supported by studies on cell lines and animal models, clinical studies
have firmly established beneficial effects of alfacalcidol on chronic-kidney disease (CKD-) related bone disease and
secondary hyperparathyroidism. Its effects on muscle structure and function are not unambiguous. Neither experimental
nor clinical data suggest beneficial effects of alfacalcidol on indicators of cardiovascular disease, including cardiovascular
calcification, left ventricular mass function or hypertension. Suggestions of improved mortality in dialysis patients treated
with alfacalcidol are based on observational cohort analyses. Integrating all available data leads the conclusion that
alfacalcidol is a justifiable compound to prescribe to CKD patients with established bone disease or hyperparathyroidism.
Monitoring of calcium and phosphorus levels after its initiation is required and dose adaptations should be made accordingly.
