Abstract
Hypoparathyroidism is a rare disease that by 2013 was the only endocrine disease for which management with the missing hormone was not approved. In 2015 the use of PTH (1-84) was approved by the FDA, however this therapy is not available in all countries and its use implies high costs for health systems. Therefore, the use of PTH (1-34) can be considered as an alternative, considering that the studies with this molecule are prior to the studies of PTH (1-84) with good results in the patients evaluated. It is important to highlight that most of the patients in the clinical studies of both molecules were patients with postsurgical hypoparathyroidism, therefore their use in patients with hypoparathyroidism not due to surgical etiology is not well established.
