1 Zemplar to hectorol conversion chart (concurrent use with vitamin D may increase the risk of hypercalcemia; however, it may be therapeutically advantageous in elderly and high-risk groups when it is necessary to prescribe vitamin D or its derivatives together with calcium; careful monitoring of serum calcium concentrations is essential during long-term therapy. - In general, vitamin D absorption will be impaired in any condition in which fat malabsorption (steatorrhea) occurs. Secondary hyperparathyroidism (prophylaxis and treatment) Paricalcitol is indicated for the prevention and treatment of secondary hyperparathyroidism associated with chronic renal failure. or reducing diets that drastically

2 restrict food selection) may not supply minimum daily requirements of vitamin D. Supplementation may be necessary in patients receiving total parenteral nutrition (TPN) or undergoing rapid weight loss or in those with malnutrition, because of inadequate dietary intake. Recommended intakes for all vitamins and most minerals are increased during pregnancy. Many physicians recommend that pregnant women receive multivitamin and mineral supplements, especially those pregnant women who do not consume an adequate diet and those in high-risk categories (i.e., women carrying more than one fetus, heavy cigarette smokers, and alcohol and drug abusers). Readily absorbed from small intestine (proximal or distal). Alfacalcidol is rapidly converted to 1,25-dihydroxycholecalciferol in the liver. Some studies have shown that infants who are exclusively breast-fed, especially from dark-skinned mothers, and/or have little exposure to sunlight may be at risk for vitamin D deficiency. {27} Therapeutic doses of specific vitamin D analogs are used in the treatment of chronic hypocalcemia, hypophosphatemia, rickets, and osteodystrophy associated with various medical conditions including chronic renal failure, familial hypophosphatemia, and

3 hypoparathyroidism (postsurgical or idiopathic, or pseudohypoparathyroidism). Some analogs have been found to reduce elevated parathyroid hormone concentrations in patients with renal osteodystrophy associated with hyperparathyroidism. Dihydrotachysterol is a synthetic reduction product of ergocalciferol; it has only weak antirachitic activity; it is metabolically activated by 25- hydroxylation in the liver. Studies have shown that the elderly may have an increased need for vitamin D due to a possible decrease in the capacity of the skin to produce previtamin D 3 or {41}. (concurrent use may impair intestinal absorption of vitamin D. Note: Bracketed information in the Indications section refers to uses that are not included in U.S. product labeling. calcitriol, and dihydrotachysterol are usually preferred in patients with renal failure since these patients have impaired ability to synthesize calcitriol from cholecalciferol and ergocalciferol; therefore, the response is more predictable. In addition, their shorter half-lives may make toxicity easier to manage (hypercalcemia reverses more quickly). Ergocalciferol may not be the preferred agent in the treatment of familial hypophosphatemia or hypoparathyroidism because the large doses needed are

4 associated with a risk of overdose and hypercalcemia; dihydrotachysterol and calcitriol may be preferred. Appropriate studies on the relationship of age to the effects of paricalcitol or doxercalciferol have not been performed in the pediatric population. Safety and efficacy have not been established. {123}. Also, calcitriol may regulate the transfer of calcium ion from bone and stimulate reabsorption of calcium in the distal renal tubule, thereby effecting calcium homeostasis in the extracellular fluid. Studies, using doxercalciferol, in rats and rabbits, at doses up 20 micrograms/kg/day (mcg/kg/day) and 0.1 mcg/kg/day (approximately 25 times and less than the maximum recommended human dose of 60 mcg/week based on mg/m 2 body surface area, respectively, revealed no teratogenic or fetotoxic effects due to doxercalciferol. {124}. For prophylaxis of vitamin D deficiency, dietary improvement, rather than supplementation, is advisable. For treatment of vitamin D deficiency, supplementation is preferred. During the doxercalciferol fixeddose period, the average dose of doxercalciferol was 2.1 +/- 1.3 microg and 3.1 +/- 1.8 microg in the 50 and 65% dose conversion groups, respectively. During this period mean ipth in the 50%

5 dose conversion group increased by 24 pg/ml (p = 0.017). During the dose titration period, doxercalciferol was increased to bring ipth within the target range. Calcium control was maintained with both conversion factors, while slightly better phosphorus control was seen in the 65% dose conversion group. Annualized treatment cost for doxercalciferol was 28% less expensive per patient than paricalcitol. CONCLUSION: The NCBI web site requires JavaScript to function.

Patients can be managed safely and effectively with conversion and dose titration from paricalcitol to doxercalciferol. Both conversion strategies maintained ipth at clinically satisfactory levels.

Ergocalciferol: Up to 6 months; repeated doses have a cumulative action. There is evidence that some metabolites of vitamin D are reabsorbed from

10 bile; however, the benefit to overall vitamin D status is thought to be negligible. Vitamin D, doxercalciferol, and paricalcitol have been shown to reduce parathyroid hormone levels. {123}. Calcitriol does not require metabolic activation. Degradation also occurs partly in the TEENney. Excessive doses of dihydrotachysterol are also teratogenic in animals. Animal studies have also shown calcifediol to be teratogenic when given in doses of 6 to 12 times the human dose. (concurrent use may impair intestinal absorption of vitamin D. {10} Ergocalciferol is indicated for prevention and treatment of vitamin D deficiency states. Vitamin D deficiency may occur as a result of inadequate nutrition, intestinal malabsorption, or lack of exposure to sunlight, but does not occur in healthy individuals receiving an adequate balanced diet and exposure to sunlight. Vitamin D therapy, alone, as treatment for osteoporosis is not generally recommended; calcitriol, and dihydrotachysterol are usually preferred in patients with renal failure since these patients have impaired ability to synthesize calcitriol from cholecalciferol and ergocalciferol; therefore, the response is more predictable. In addition, their shorter half-lives may make toxicity easier to manage (hypercalcemia reverses more

11 quickly). Ergocalciferol may not be the preferred agent in the treatment of familial hypophosphatemia or hypoparathyroidism because the large doses needed are associated with a risk of overdose and hypercalcemia; dihydrotachysterol and calcitriol may be preferred. cholecalciferol is found in vitamin D fortified milk. Cholecalciferol and ergocalciferol are transferred to the liver where they are converted to calcifediol (25- hydroxycholecalciferol), which is then transferred to the TEENneys and converted to calcitriol (1,25- dihydroxycholecalciferol, thought to be the most active form) and 24,25-dihydroxycholecalciferol (physiologic role not determined). Overdosage of vitamin D has been associated with fetal abnormalities in animals. Animal studies have shown calcitriol to be teratogenic when given in doses 4 and 15 times the dose recommended for human use. Because of varying sensitivity, some infants may be sensitive to even small doses. Recommended intakes for all vitamins and most minerals are increased during breast-feeding. Tetany (prophylaxis and treatment) Dihydrotachysterol is indicated [and ergocalciferol and calcitriol are used]. Ergocalciferol has not been proven effective for treatment of

12 lupus vulgaris or rheumatoid arthritis, or prevention of nearsightedness or nervousness. There are insufficient data to show that vitamin D supplementation is beneficial in the treatment of psoriasis. - Hepatic-biliary tract disease hepatic function impairment, cirrhosis, obstructive jaundice. Exposure of the skin to ultraviolet rays in sunlight results in formation of cholecalciferol (vitamin D 3 ). There is evidence that some metabolites of vitamin D are reabsorbed from bile; however, the benefit to overall vitamin D status is thought to be negligible. Because of varying sensitivity, some infants may be sensitive to even small doses. Only small amounts of vitamin D metabolites appear in human milk. however, vitamin D supplements in doses of 400 to 800 Units may be used as part of the prevention and treatment of osteoporosis in patients with an inadequate vitamin D and/or calcium intake.
