In the United States, secondary hyperparathyroidism affects a significant portion of individuals with chronic kidney disease (CKD). When considering treatment options, patients and healthcare providers often compare Hectorol and Zemplar, two common vitamin D analogs. While both medications are used to lower elevated parathyroid hormone (PTH) levels, understanding the nuances behind their active ingredients, potency, and side effects is crucial to answering the question, 'What is the difference between Hectorol and Zemplar?'

Zemplar and calcitriol are not the same medication, despite both being active forms of vitamin D used to treat complications related to chronic kidney disease. While calcitriol is a synthetic version of the body's natural active vitamin D hormone, Zemplar (paricalcitol) is a modified, synthetic analog with a more selective action. This distinction is crucial for patient outcomes, especially concerning the management of secondary hyperparathyroidism.
