Patient Medication Information: uses, side effects, how to take - Auro-Cinacalcet
ABOUT THIS MEDICATION
What the medication is used for:
Auro-Cinacalcet is used:
- to treat secondary hyperparathyroidism (high-per-pear-uh-THIGH-royd-izm) in patients with chronic kidney disease (CKD) receiving dialysis;
- to reduce high levels of calcium in the blood (hypercalcemia) in patients with parathyroid cancer;
- to reduce high levels of calcium in the blood (hypercalcemia) in patients with primary hyperparathyroidism when removal of the gland(s) is not possible.
What it does:
Four small glands located behind the thyroid gland in your neck are called parathyroid glands. They make a hormone called parathyroid hormone (PTH). Normally, PTH makes sure you have just enough calcium and phosphorus in your blood to keep your bones, heart, muscles, nerves and blood vessels working well.
Secondary hyperparathyroidism
When your kidneys are working, PTH keeps your calcium and phosphorus levels normal by moving the right amounts of calcium and phosphorus in and out of your bones. Chronic Kidney Disease (CKD) can cause a condition called secondary hyperparathyroidism.
When your kidneys aren’t working properly, the calcium and phosphorus balance in your body is upset, and your parathyroid glands send out too much PTH to your body. This can cause bone disease and also may be a risk factor for heart disease and abnormal calcification of blood vessels and other parts of the body. Auro-Cinacalcet treats secondary hyperparathyroidism by lowering PTH. This helps keep calcium and phosphorus within proper levels.
Parathyroid carcinoma/Primary hyperparathyroidism
Primary hyperparathyroidism is caused by an overactive, enlarged parathyroid gland (or glands), occasionally due to cancer of the parathyroid gland. In primary hyperparathyroidism, your parathyroid glands send out too much PTH to your body and your blood level of calcium becomes high. Auro-Cinacalcet lowers PTH by telling your parathyroid glands to stop releasing too much PTH into your blood. This helps lower your blood calcium levels.
When it should not be used:
You should not take Auro-Cinacalcet if you are hypersensitive (allergic) to any of the ingredients in the tablet.
You should not take Auro-Cinacalcet if your blood calcium level is below the normal range.
