Summary for Patent: 5,597,815

Title: Prevention of hyperphosphatemia in kidney disorder patients
Abstract:The 19-nor-vitamin D analogs, and particularly 19-nor-1.alpha.,25-dihydroxyvitamin D.sub.2, possess low calcemic and phosphatemic activity while also having the ability to suppress parathyroid hormone (PTH) production. The suppressive effect on PTH secretion of these 19-nor analogs without significant changes in serum calcium or serum phosphorus make them ideal tools for the treatment of secondary hyperparathyroidism in patients having kidney disorders.
