Treats volume depletion from calcium-induced urinary salt wasting
Increases renal perfusion and urinary calcium clearance
Administration: Initial rate of 200-300ml/hr adjusted for urinary output of 100ml/h
Limited in those with cardiac or renal disease
Should be discontinued with development of edema
Rarely normalizes calcium levelWays to Correct Hypercalcemia
