Calcitetrol is primarily used in the treatment of conditions related to calcium and bone metabolism. It is effective in managing hypocalcemia in patients with chronic kidney disease, particularly those undergoing dialysis, as it helps regulate calcium and phosphate levels in the blood. Additionally, it is utilized in the treatment of secondary hyperparathyroidism, a condition often associated with kidney failure, by suppressing the overproduction of parathyroid hormone. Calcitetrol is also prescribed for patients with hypoparathyroidism to maintain adequate calcium levels and prevent bone disorders. Its role in promoting calcium absorption in the intestines and supporting bone mineralization makes it a valuable therapeutic agent in managing these metabolic disorders.
