ABOUT THE DISEASE

Chronic Renal Failure:

Individuals with renal failure cannot transform enough vitamin D into calcitriol naturally, causing low levels of calcium in the blood and bone disorders. This medication helps to increase the amount of vitamin D in the body by overpassing the conversion step in the kidneys. Common disorders associated with chronic renal failure are:

  • Hypocalcemia: when the body does not absorb enough calcium
  • Secondary hyperparathyroidism: excess parathyroid hormone production as a result of renal failure
  • Osteodystrophy: alterations in bones due to renal failure
