title: Improvement of the absorption of 3H-Cholecalciferol by formation of its cyclodextrin complex.
abstract: Following oral administration to rats of beta-cyclodextrin inclusion complex of 3H-labelled vitamin D3 (cholecalciferol) resulted in significantly higher blood radioactivity as with the non-complexed vitamin. Difference in the first 90 min was 2,3-2,8 fold, and it remained significantly higher up to the 6th h. After 24 h there was no difference between the blood radioactivity of animals treated with complexed and with non-complexed vitamin D3.
