Used in the treatment of secondary hyperparathyroidism in adult patients with chronic kidney disease on hemodialysis. It works by suppressing parathyroid hormone levels, helping to regulate calcium and phosphorus balance in the blood. This reduces the risk of complications such as bone disorders and cardiovascular issues associated with mineral imbalances. Administered intravenously during dialysis sessions, it offers a targeted approach for patients who may not respond adequately to other therapies.
