Natpar, also known by its generic name parathyroid hormone or parathormone, is a prescription medication used primarily in the management of hypoparathyroidism, a condition characterized by insufficient levels of parathyroid hormone (PTH) in the body. This hormone plays a crucial role in regulating calcium and phosphate levels in the blood, essential for maintaining healthy bone structure and function. Natpar, as a synthetic form of human parathyroid hormone (1-84), works by mimicking the actions of natural PTH, thereby helping to control calcium levels, reduce the risk of hypocalcemia (low blood calcium levels), and improve bone metabolism. It is typically administered via injection and is used when other treatments have not been effective. As with any medication, the use of Natpar should be closely monitored by a healthcare provider to manage any potential side effects and ensure its efficacy in treating hypoparathyroidism.
