Active form (calcitriol) binds VDR promoting intestinal calcium and phosphorus absorption, bone mineralization, and parathyroid hormone regulation.
Calcitriol: used for renal secondary hyperparathyroidism and hypoparathyroidism. Narrow therapeutic index — hypercalcemia risk. Monitor ionized calcium frequently. Do not confuse calcitriol with cholecalciferol.
Species-specific contraindications and adverse-reaction reports for dog may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Vitamin D pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dog — the rules above are the citations specific to this species, not generic recommendations.
