Summary
The administration of 1,25-dihydroxycholecalciferol to rats increased their calciuresis as a power function of the dose. Up to 95% of the urinary calcium was excreted as a non-ionized complex, together with equimolar amounts of citrate. The stoichiometry between calcium and citrate, observed at all dose levels, suggests that citrate metabolism is coordinated with the mobilization of calcium.
