Etelcalcetide (trade name: Parsabiv) is a prescription medicine used to treat secondary hyperparathyroidism (HPT) in adults with chronic kidney disease (CKD) who are on hemodialysis. It is a calcimimetic agent that works by mimicking certain naturally occurring calcium molecules in order to reduce parathyroid hormone (PTH) levels in the blood. Etelcalcetide is injected under the skin three times a week in the course of a dialysis treatment. Common side effects include nausea, vomiting, diarrhea, headache, and anemia.
Etelcalcetide (trade name Parsabiv) is a medication used to treat a specific condition related to the kidneys. Here's a breakdown of its key points:
Function:
- Etelcalcetide is a calcimimetic drug, which means it mimics the effects of calcium in the body.
- It works by targeting the calcium-sensing receptor (CaSR) located on the parathyroid gland. The parathyroid gland produces parathyroid hormone (PTH), which regulates calcium levels in the blood.
- By activating the CaSR, Etelcalcetide suppresses the production of PTH, thereby helping to control high levels of PTH.
Medical Condition:
- Etelcalcetide is specifically used to treat secondary hyperparathyroidism in adults with chronic kidney disease (CKD) undergoing hemodialysis.
Secondary Hyperparathyroidism:
- In healthy individuals, the parathyroid gland regulates PTH production based on calcium levels in the blood. When calcium levels drop, PTH increases to stimulate calcium release from bones and absorption from the intestines.
- In people with chronic kidney disease, the kidneys are unable to effectively remove excess phosphorus from the blood. This leads to a compensatory increase in PTH production (secondary hyperparathyroidism) in an attempt to maintain calcium balance.
Administration:
- Etelcalcetide is administered intravenously (IV) at the end of each hemodialysis session.
Benefits:
- By controlling PTH levels, Etelcalcetide can help prevent complications associated with secondary hyperparathyroidism, such as bone disease and increased risk of fractures.
Side Effects:
- Common side effects include nausea, vomiting, diarrhea, muscle cramps, and low blood calcium levels (hypocalcemia).
Important Considerations:
- Etelcalcetide is not suitable for everyone, particularly those with existing low blood calcium levels.
- Regular monitoring of blood calcium levels is crucial while taking Etelcacetide.
- It's important to disclose all medications you are taking to your doctor, as Etelcalcetide can interact with some drugs.
