Patient leaflet - Cinacalcet Amarox 30 mg film-coated tablets
1. What Cinacalcet is and what it is used for
Cinacalcet works by controlling the levels of parathyroid hormone (PTH), calcium and phosphorous in your body. It is used to treat problems with organs called parathyroid glands. The parathyroids are four small glands in the neck, near the thyroid gland, that produce parathyroid hormone (PTH).
Cinacalcet is used in adults:
to treat secondary hyperparathyroidism in adults with serious kidney disease who
need dialysis to clear their blood of waste products.
to reduce high levels of calcium in the blood (hypercalcaemia) in adult patients with
parathyroid cancer.
to reduce high levels of calcium in the blood (hypercalcaemia) in adult patients with
primary hyperparathyroidism when removal of the gland is not possible.
Cinacalcet is used in children aged 3 years to less than 18 years of age:
to treat secondary hyperparathyroidism in patients with serious kidney disease who
need dialysis to clear their blood of waste products, whose condition is not controlled with other treatments.
In primary and secondary hyperparathyroidism too much PTH is produced by the parathyroid glands. “Primary” means that the hyperparathyroidism is not caused by any other condition and “secondary” means that the hyperparathyroidism is caused by another condition, e.g. kidney disease. Both primary and secondary hyperparathyroidism can cause the loss of calcium in the bones, which can lead to bone pain and fractures, problems with blood and heart vessels, kidney stones, mental illness and coma.
