Patient Education

Calcitriol


Calcitriol is used to treat and prevent low levels of calcium and bone disease in patients whose kidneys or parathyroid glands (glands in the neck that release natural substances to control the amount of calcium in the blood) are not working normally. It is also used to treat secondary hyperparathyroidism (a condition in which the body produces too much parathyroid hormone [PTH; a natural substance needed to control the amount of calcium in the blood]) and metabolic bone disease in people with kidney disease. Calcitriol is in a class of medications called vitamin D analogs. It works by helping the body to use more of the calcium found in foods or supplements and regulating the body's production of parathyroid hormone.

Calcitriol Topical


Calcitriol topical is used to treat mild to moderate plaque psoriasis (a skin disease in which red, scaly patches form on some areas of the body) in adults and children 2 years of age and older. Calcitriol is in a class of medications called vitamin D analogs. It works by helping to stop the production of extra skin cells that may build up and form scales on the skin and by decreasing the activity of immune cells in the skin.
