The following information is a summary about Sensipar. It is not intended to replace a doctor's instructions.
What is cinacalcet?
Cinacalcet is an agent that increases the sensitivity of the parathyroid gland to calcium in the
body. This causes a decrease in levels of parathyroid hormone (PTH), calcium, and phosphorous in
the body.
Cinacalcet is used to reduce elevated levels of parathyroid hormone (PTH) in people with
chronic renal disease who are on dialysis. Cinacalcet is also used to lower calcium levels in patients with
cancer of the parathyroid gland.
Cinacalcet may also be used for purposes other than those listed in this medication guide.
