PHARMACOLOGY
Vitamin D regulates the calcium- and phosphate balance. Cholecalciferol and toan even greater extent its hydroxylation products induce the formation of acalcium transport protein in the mucous membrane of the small intestine. Thisleads to increased absorption of calcium and phosphate from the intestine. In thekidneys vitamin D stimulates the reabsorption of calcium and phosphate. Avitamin D deficiency leads to rickets in the growing organism and osteomalacia inadults.
PHARMACOKINETIC
- Absorption: Cholecalciferol is easily absorbed from the gastrointestinal tract inthe presence of bile. In case of reduced fat absorption, the absorption of vitaminD is also reduced.
- Distribution: Cholecalciferol can be stored in adipose- and muscle tissue for along time. The effect of cholecalciferol starts slowly and is long lasting effect. Itshalf-life is 19-25 hours.
- Metabolism: The active form of Cholecalciferol is 1,25-dihydroxycholecalciferol,which is formed by hydroxylation of cholecalciferol in liver and kidneys.
- Elimination: Cholecalciferol and its metabolites are excreted mainly in the bileand faeces. Small amounts appear in the urine.

SPECIAL PRECAUTIONS FOR USE
- Vitamin D should be given with caution in patients with sarcoidosis and othergranulomatous disorders due to the risk of increased metabolization of vitaminD to its active form. These patients should be monitored for the calcium contentin serum and urine.

- In long-term treatments, renal and urinary calcium levels and serum creatininemeasurement should be checked every 3 to 6 months. These controls areparticularly important in elderly patients and in concomitant treatment withcardiac glycosides or diuretics.
