Calcitriol belongs to the group of medications called vitamin D3 metabolites. Calcitriol is a form of vitamin D that is active in the body. It helps to maintain the balance of calcium and phosphorus in the blood. It also helps bones absorb calcium.
Calcitriol is used to help increase the amount of calcium in the blood and help with proper bone formation for people with chronic kidney failure that are undergoing dialysis. It is also used to increase the amount of calcium in the blood for people whose parathyroid glands are not working effectively, such as after surgery. Calcitriol may also be used to treat vitamin D-resistant rickets, a bone disease caused by too little vitamin D.
