Decalcitrol is indicated for the treatment of hypocalcemia, secondary hyperparathyroidism associated with chronic kidney disease, and hypoparathyroidism. It may also be used in the management of rickets and osteomalacia when vitamin D supplementation is required.
As the active form of vitamin D3 (1,25-dihydroxyvitamin D3), Decalcitrol works by increasing intestinal absorption of calcium and phosphorus, promoting bone mineralization, and regulating parathyroid hormone secretion to maintain normal serum calcium levels.
Decalcitrol should be used with caution in patients with hypercalcemia, kidney stones, or impaired renal function. Regular monitoring of serum calcium, phosphorus, and parathyroid hormone levels is essential during treatment to avoid toxicity. Patients should avoid taking other vitamin D supplements concurrently unless directed by a healthcare provider.
