It contains 84 amino acids and has a terminal half-life of approximately 3 hours1

Amino acid sequence of PTH1

NATPARA is administered once per day1

Mean (±SE) unadjusted PTH and albumin-corrected serum calcium concentration following 100 mcg SC administration in patients with hypoparathyroidism 1

Treatment with NATPARA increases serum calcium levels, which are sustained for more than 24 hours after administration.

Mean peak serum calcium levels are reached between 10 and 12 hours following a single subcutaneous injection, and the increase in serum calcium above baseline is sustained for more than 24 hours after administration.

Peak plasma concentrations of NATPARA occur within 5 to 30 minutes with a second, usually smaller, peak at 1 to 2 hours.
