Used primarily in the management of secondary hyperparathyroidism in patients with chronic kidney disease on dialysis. It helps control elevated parathyroid hormone levels by sensitizing calcium-sensing receptors in the parathyroid gland. Also indicated for treating hypercalcemia in patients with parathyroid carcinoma or primary hyperparathyroidism when surgery is not an option. Works by lowering serum calcium and parathyroid hormone levels, reducing the risk of complications related to mineral imbalances.
