Mechanism
Etelcalcetide is a calcimimetic that activates the calcium-sensing receptor (CaSR). This activation, particularly in the parathyroid gland, leads to inhibition of parathyroid hormone (PTH) secretion.
Indications
Secondary hyperparathyroidism in patients with chronic kidney disease on haemodialysissecondary hyperparathyroidism in adults with chronic kidney disease (CKD) on dialysis
Dosing
- Adult
- ▶ BY MOUTH ▶ Adult: Initially 30 mg twice daily (max. per dose 90 mg 4 times a day), dose to be adjusted every 2–4 weeks according to response Hypocalcaemia Conditions that may worsen with a decrease in serum-calcium concentrations .…
Pharmacokinetics
Onset
plasma concentrations reach steady state approximately 8 weeks after thrice-weekly dosing
Half-life
3 to 5 days (in hemodialysis patients)
Excretion
cleared by renal excretion in patients with normal kidney function; hemodialysis is the predominant elimination pathway in patients receiving hemodialysis
Contraindications
- Hypocalcaemia
- initial serum calcium <8.4 mg/dL
Side effects
Common
Nausea
Serious
- Hypocalcaemia
- hypocalcemia
- lowered seizure threshold (with significant reductions in serum Ca2+)
- adynamic bone disease (if PTH level falls below 100 pg/mL)
- worsening of heart failure
- upper gastrointestinal bleeding
