vitamin D2; a sterol occurring naturally in fungi and some fish oils or synthesized from ergosterol, and similar to cholecalciferol in activity and metabolism; it is administered orally or added to food (e.g., milk) as a dietary source of vitamin D. It is also used in treatment of hypocalcemia, hypophosphatemia, rickets, and osteodystrophy associated with various medical conditions including chronic renal failure and hypoparathyroidism, administered orally, intramuscularly, or intravenously.

(er'gō-kal-sif'ĕr-ol),
Activated ergosterol, the vitamin D of plant origin; it arises from ultraviolet irradiation of ergosterol, which is cleaved at the 9,10 bond and develops a double bond between C-10 and C-19; used in prophylaxis and treatment of vitamin D deficiency.

ergocalciferol

Vitamin D2. This is produced in the body by the action of ultraviolet light on ergosterol. Vitamin D is necessary for the normal mineralization of bone. Deficiency leads to RICKETS in growing children and bone softening (OSTEOMALACIA) in adults. The drug is on the WHO official list.

Although ergocalciferol was used because it is an FDA-approved medication for the treatment of low vitamin D, cholecalciferol ([D.sub.3]) has been reported to be a more potent vitamin [66] and is currently being used in clinical trials.
In one of the reported cases, the patient had persistent vitamin D deficiency despite treatment with a very high dose of vitamin D (ergocalciferol 100,000 IU/week).

Their identification and subsequent treatment with cholecalciferol (Vitamin D3) or ergocalciferol (Vitamin D2) in order to obtain adequate seric levels, allows a greater amount of substrate for the proximal convoluted tubule cells, and then inside improve the synthesis of the active form of vitamin D (calcitriol or 1,25(OH)2D) in patients with CKD without dialysis requirements, avoiding the development of all complications from hyperparathyroidism.
As mentioned previously, forms of vitamin D included vitamin D2 (ergocalciferol), vitamin D3 (cholecalciferol), calcitriol (1,25-hydroxyvitamin D3), paricalcitol, and doxerocalciferol.

These results are different from the findings by Leaf and colleagues, where the authors gave VD repletion therapy (ergocalciferol 50 000 IU/week) for 8 weeks without calcium supplementation.
