  • Patent number: 11452734
    Abstract: The method of treating elevated blood levels of iPTH by increasing or maintaining blood concentrations of both 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D in a patient by administering, as necessary, both Vitamin D repletion and Vitamin D hormone replacement therapies, is disclosed. The blood concentrations of 25-hydroxyvitamin D are increased to and maintained at or above 30 ng/mL, and blood concentrations of 1,25-dihydroxyvitamin D are increased to or maintained within a patient's normal historical physiological range for 1,25-dihydroxyvitamin D without causing substantially increased risk of hypercalcemia, hyperphosphatemia or over suppression of plasma iPTH in the patient. The blood levels of 25-hydroxyvitamin D are maintained at or above 30 ng/mL between doses of Vitamin D repletion therapies, and the blood levels of 1,25-dihydroxyvitamin D are maintained in the patient's normal historical physiological range between doses of Vitamin D hormone replacement therapies.
