calcium citrate
calcium supplement - oral
- Fewer GI problems

- Can take without food
calcium gluconate
cal supplement - IV
- Least irritating to veins of IV Ca preps
- Rapid infusion can cause arrhythmias
cholecalciferol
vitamin D3
made by animals
ergocalciferol
vit D2
- D2 is made by plants, D3 by animals
- D3 is considered more physiological
- D2 is prescribed more - this is because D3 is in supplements (we don’t like that because they can put whatever they want in there) - if we prescribe D2 then we know exactly what is in there
- causes of vit D def
- Inadequate dietrary intake
- Inadequate exposure to light
- Renal dysfunction
- Adminiatration of anticonvulsants (such as phenobarbital, phentoin) that increase metabolism of 25 (OH)D
- Pharmacolic uses of Vit D
- Nutritional rickets - prophylaxis and treatment
- Metabolic rickets (due to genetic defect in the renal hydroxylase or due to chronic renal failure) calcitrol is used since patients can bioactivate vitamin D2 or D3
- Osteoporosis and osteomalacia - in combination with calcium
- Psoriasis: calcipotriene - topical
- Hypoparathyroidism -> low 1,25(OH2)D - can use any med: D2, D3, or calcitriol
- Secondary hypoparathyroidism in renal disease -> low 1,25(OH)2D - doxercalciferol, paricalitol (this is the major time you would use these drugs)
calcitriol
vit D (1,25 OH2 vitamine D (active vit D)
calcipotriene
vit D
doxercalciferal
vit D
paracalcitrol
vit D
