This medicine contains the active ingredient calcitriol, which is a biologically active form of vitamin D. Vitamin D is very important for maintaining health of our bones and teeth, and it regulates the amount of calcium and phosphate in the body. Most common disturbance in the body’s calcium levels comes from kidney disorders, disorders of the parathyroid glands, low blood calcium. Calcitriol takes calcium from food and helps with strengthening and growth of the bones. It is prescribed for the prevention and treatment of vitamin D deficiency, and some conditions that cause problems with the bones, like renal osteodystrophy and postmenopausal osteoporosis.
