What medical options should be considered for the treatment of primary hyperparathyroidism?

Primary hyperparathyroidism (PHPT) is a common, often asymptomatic, endocrine disorder characterized by hypercalcaemia in the face of a nonsuppressed parathyroid hormone (PTH) level. For those with symptomatic disease or who meet surgical criteria, parathyroidectomy is the treatment of choice. However, those patients who do not meet surgical criteria or who cannot undergo or refuse surgery must be managed medically. Medical management of PHPT involves continual assessment to determine who will benefit from surgical intervention, replacement of vitamin D, treatment of parathyroid bone disease and management of hypercalcaemia and renal stone disease.
