Cholecalciferol Versus Doxercalciferol in the Treatment of Secondary Hyperparathyroidism in Chronic Kidney Disease

Patients with CKD stage 3 were randomly allocated (by blinded group allocation) to either cholecalciferol (4000 U per day for one month then 2000 IU daily thereafter) or doxercalciferol (2.5 mcg po daily. Assessments for blood endpoints (primary end point PTH; secondary calcium, phosphorus) were done monthly. Other assessments (blood pressure) were done at baseline and at 3 months.
