Etelcalcetide

How it works

Mimics calcium at the parathyroid's calcium-sensing receptor, so the glands release less parathyroid hormone. Given after dialysis.

What it's made of

Seven amino acids in their “mirror” form (D), joined by a sulfur bridge to a normal cysteine. It does not copy any hormone: it mimics calcium at the sensor of the parathyroid glands.

What it's for

Prescribed for

Secondary hyperparathyroidism in adults with chronic kidney disease on hemodialysis.
