Just came across this, while searching for things unrelated ( - and felt it, a ?patentable drug, may be of interest to others !):
NATPARA - for the treatment of hypoparathyroidism
* On January 23, 2015 it was announced that the FDA had approved NATPARA as
an adjunct to calcium and vitamin D to control hypocalcemia in patients
with hypoparathyroidism. Hypoparathyroidism is a rare endocrine disorder
characterized by insufficient levels of parathyroid hormone, or PTH.
NATPARA is a bioengineered replica of human PTH. NATPARA was launched on
April 1, 2015.
(Have to wonder if such a product would be essential for those with parathyroid glands removed ?)
