Calcitriol

Pronounced

"kal-SIT-ree-ole"

Uses

Calcitriol is a man-made active form of vitamin D (vitamin D3). Vitamin D is a vitamin stored in the body that is needed for building and keeping strong bones. Calcitriol is used to treat or prevent certain problems that can happen with long-term kidney dialysis, such as low levels of calcium or high levels of parathyroid hormone. Calcitriol is usually used along with a certain diet, supplements, and sometimes other medications.

Most people get enough vitamin D from exposure to the sun and from fortified food products (such as dairy products, vitamins). Before regular vitamin D can be used by the body, it needs to be changed to the active form by the liver and kidneys. People with kidney disease cannot make enough of the active form of vitamin D. This medication works by affecting parathyroid hormone (PTH) levels and increasing blood calcium levels.
