Alfacalcidol is an analog of vitamin D and offers uses in treating a wide range of conditions because of changes in calcium levels. It is an analog of vitamin D hormone that gets activated by specific enzymes in the liver. Calcitriol (vitamin D3) is the active metabolite of Alfacalcidol, which helps regulate bone metabolism and correction of the calcium balance in a variety of calcium deficiency conditions.

We associate most Alfacalcidol uses with regulation of calcium levels. Some uses of Alfacalcidol are:

  • Chronic kidney failure– Disorders of the kidney lead to low levels of calcium. Doctors use Alfacalcidol in patients who are on dialysis because of chronic renal failure.

3. Is Alfacalcidol a Vitamin D?

Alfacalcidol is a version of vitamin D that converts to calcitriol, an active form of vitamin D. Alfacalcidol finds its uses as a vitamin D supplement in various deficiency disorders. It is also helpful to treat hypocalcaemia, or low calcium levels in the blood because of calcium metabolism disorders.

4. What is the difference between Alfacalcidol and Vitamin D?

Alfacalcidol is a version of the vitamin D hormone. It undergoes conversion to calcitriol in the liver, which is the active form of vitamin D3. The pure form of vitamin D is not suitable as a nutritional supplement because its activation is not possible in most patients. Alfacalcidol increases the availability of active vitamin D as it bypasses the regulatory mechanism.

5. When should I take Alfacalcidol?

Follow your doctor’s advice while using Alfacalcidol. Alfacalcidol has a daily dose regimen.

Alfacalcidol is a version of vitamin D that helps improve the absorption of calcium. Sometimes doctors may recommend Alfacalcidol with calcium preparations to aid the uptake of calcium in the blood.
