Cinacalcet
Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Cinacalcet is an oral calcimimetic used for secondary hyperparathyroidism in adults on dialysis and for hypercalcemia in parathyroid carcinoma or selected primary hyperparathyroidism patients. It lowers parathyroid hormone and serum calcium, so hypocalcemia, QT prolongation from hypocalcemia, seizures, and worsening heart failure symptoms are key safety concerns.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Cinacalcet is an oral calcimimetic used for secondary hyperparathyroidism in adults on dialysis and for hypercalcemia in parathyroid carcinoma or selected primary hyperparathyroidism patients. NutriStack rates the supporting evidence as strong. Common adult dosing is Secondary hyperparathyroidism in adults on dialysis: start 30 mg orally once daily and titrate every 2 to 4 weeks by PTH and calcium. Parathyroid carcinoma or primary hyperparathyroidism: often 30 mg twice daily initially, titrated to calcium response., though a prescriber sets the actual dose. With long-term use it can deplete calcium. This profile indexes 3 sources.
The bottom line
Evidence rating strong. Most-documented uses: reduced pth in dialysis-related secondary hyperparathyroidism, reduced hypercalcemia in parathyroid carcinoma, reduced serum calcium in selected primary hyperparathyroidism when surgery is not appropriate. 3 sources indexed (2012–2026), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Cinacalcet allosterically increases sensitivity of the calcium-sensing receptor on parathyroid cells to extracellular calcium. This suppresses parathyroid hormone secretion, which lowers serum calcium and can lower phosphorus in some settings. Metabolism involves CYP3A4, CYP2D6, and CYP1A2, and calcium changes require close biochemical monitoring.3,1
Dosing & protocol.
Take with food or shortly after a meal to improve exposure. Do not start if corrected serum calcium is below the lower limit of normal.

What is Cinacalcet?
Cinacalcet is an oral calcimimetic used for secondary hyperparathyroidism in adults on dialysis and for hypercalcemia in parathyroid carcinoma or selected primary hyperparathyroidism patients. It lowers parathyroid hormone and serum calcium, so hypocalcemia, QT prolongation from hypocalcemia, seizures, and worsening heart failure symptoms are key safety concerns.
What is Cinacalcet used for?
Commonly cited benefits of Cinacalcet include: Reduced PTH in dialysis-related secondary hyperparathyroidism; Reduced hypercalcemia in parathyroid carcinoma; Reduced serum calcium in selected primary hyperparathyroidism when surgery is not appropriate; Adjunctive control of CKD mineral and bone disorder parameters. NutriStack rates the overall evidence as strong.
What is a typical dose of Cinacalcet?
A typical adult dose of Cinacalcet is Secondary hyperparathyroidism in adults on dialysis: start 30 mg orally once daily and titrate every 2 to 4 weeks by PTH and calcium. Parathyroid carcinoma or primary hyperparathyroidism: often 30 mg twice daily initially, titrated to calcium response.. The commonly recommended form is Oral tablet taken with food or shortly after a meal. These are general ranges, not personalized advice; confirm the right dose with a clinician.
What are the side effects of Cinacalcet?
Reported side effects include nausea, vomiting, diarrhea, myalgia, dizziness, hypocalcemia. This is educational information; check with a healthcare professional before use.
How strong is the evidence for Cinacalcet?
NutriStack rates this as Strong, meaning multiple high-quality meta-analyses or systematic reviews converge on the same finding. Full tier criteria are at https://nutristackapp.com/methodology/evidence-tiers.
