Calcimimetic agent that allosterically modulates the calcium-sensing receptor (Ca SR) on parathyroid chief cells, increasing its sensitivity to extracellular calcium, thereby reducing parathyroid hormone (PTH) secretion.
Digitalis glycoside; inhibits Na+/K+-ATPase, increasing intracellular calcium and cardiac contractility.
Secondary hyperparathyroidism in patients with chronic kidney disease on dialysis,Hypercalcemia in patients with parathyroid carcinoma,Severe hypercalcemia in patients with primary hyperparathyroidism who are unable to undergo parathyroidectomy
Heart failure,Atrial fibrillation,Atrial flutter
30 mg orally once daily, titrated every 2-4 weeks to a maximum of 180 mg once daily to achieve target i PTH reduction.
0.05 to 0.2 mg intravenously or intramuscularly, administered slowly over 5 minutes; initial dose 0.15 to 0.2 mg, then 0.1 to 0.15 mg every 30 minutes up to a total of 0.4 mg. Oral: 0.05 to 0.2 mg daily for maintenance.
The terminal elimination half-life of cinacalcet is approximately 30 to 40 hours in patients with normal renal function, supporting once-daily dosing. Steady-state concentrations are achieved within 7 days.
Terminal elimination half-life is 36-48 hours in patients with normal renal function; prolonged to >100 hours in severe renal impairment, requiring dose adjustment.
Hepatic via CYP3A4, CYP2D6, CYP1A2; major metabolites are inactive.
Hepatic (minor); primarily renally excreted unchanged.
Renal excretion of unchanged drug and metabolites accounts for approximately 84% of the administered dose; fecal excretion accounts for approximately 11%. The primary metabolic pathway is CYP3A4-mediated oxidation, followed by glucuronidation.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 30-40%, with enterohepatic circulation present.
Cinacalcet is approximately 93 to 97% bound to plasma proteins, primarily to albumin and alpha-1-acid glycoprotein.
25-30% bound to plasma albumin.
The volume of distribution is approximately 1000 L (about 14 L/kg in a 70 kg individual), indicating extensive tissue distribution.
6-10 L/kg; large Vd indicates extensive tissue distribution and high cardiac tissue affinity.
Oral bioavailability is approximately 20 to 25% due to first-pass metabolism; administration with food increases bioavailability by approximately 50% compared to fasting.
Oral: 70-80%; IV: 100%.
No dose adjustment required for mild to moderate renal impairment (Cr Cl >= 30 m L/min). Not recommended for patients with severe renal impairment (Cr Cl < 30 m L/min) due to lack of data.
GFR <50 m L/min: reduce dose by 50% or extend dosing interval to every 36-48 hours. GFR <10 m L/min: avoid use or reduce dose by 75%.
No dose adjustment required for mild to moderate hepatic impairment (Child-Pugh Class A or B). Use with caution in severe hepatic impairment (Child-Pugh Class C) with no specific dose recommendations.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 25-50%. Child-Pugh Class C: avoid use or reduce dose by 75%.
Safety and effectiveness in pediatric patients have not been established.
Digitalizing dose: 0.01-0.02 mg/kg IV or IM, given in divided doses over 24 hours. Maintenance: 10-20% of digitalizing dose daily. Not recommended for neonates due to prolonged half-life.
No specific dose adjustment; dosing should be based on renal function. Elderly patients may have decreased renal function; monitor serum calcium and i PTH levels closely.
Reduce dose by 25-50% due to decreased renal function and increased sensitivity. Monitor serum levels and renal function closely.
None.
Can cause potentially fatal arrhythmias; use only when clearly indicated and monitor serum levels.
Hypocalcemia: monitor serum calcium, especially during initiation and dose titration,Seizures: risk due to hypocalcemia,QT prolongation: caution in patients with history of QT interval prolongation or on concurrent QT-prolonging drugs,Hypotension: possible during dialysis use,Adynamic bone disease: potential with oversuppression of PTH
Narrow therapeutic index; toxicity risk increased with hypokalemia, hypomagnesemia, hypercalcemia, renal impairment; monitor ECG and drug levels.
Hypocalcemia (serum calcium < 8.4 mg/d L)
Ventricular fibrillation, digitalis toxicity, hypersensitivity, AV block (unless pacemaker present), Wolff-Parkinson-White syndrome.
SENSIPAR should be taken with food or shortly after a meal to enhance absorption. No specific foods are contraindicated, but avoid high-calcium meals immediately before or after dosing as they may reduce absorption. Grapefruit and grapefruit juice may increase cinacalcet levels; avoid concurrent use.
Avoid licorice, which can cause hypokalemia. Maintain consistent intake of potassium-rich foods (bananas, oranges) to avoid fluctuations. No known significant food interactions beyond electrolyte effects.
First trimester: Limited human data; animal studies show fetal harm at high doses (reduced fetal weight, skeletal variations). Second/third trimester: No adequate human studies; potential fetal/neonatal hypocalcemia due to maternal calcium-sensing receptor modulation. Risk cannot be excluded.
Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk. Second/third trimester: Risk of fetal bradycardia, cardiac glycoside toxicity; avoids if possible.
No human data on excretion in breast milk; M/P ratio unknown. Potential for serious adverse reactions (e.g., hypocalcemia) in nursing infants; decision to discontinue breastfeeding or drug based on importance of drug to mother.
Deslanoside is excreted in breast milk; estimated infant dose 0.1-0.5% of maternal weight-adjusted dose; M/P ratio not well defined. Monitor infant for bradycardia, feeding difficulties; benefit likely outweighs risk.
No specific dose adjustment guidelines; pharmacokinetics in pregnancy unknown. Monitor serum calcium frequently and adjust dose to maintain target calcium levels. Consider that volume of distribution and clearance may increase, potentially requiring higher doses.
Increased renal clearance in pregnancy may require higher doses; monitor serum drug levels and adjust accordingly. Reduced dosing in third trimester may be needed due to volume expansion.
SENSIPAR (cinacalcet) is a calcimimetic used for secondary hyperparathyroidism in CKD on dialysis and for hypercalcemia in parathyroid carcinoma. Monitor serum calcium closely; hypocalcemia is a common adverse effect. Do not initiate if serum calcium is below the lower limit of normal. Administer with food or shortly after a meal to increase absorption. Dose adjustments may be needed with moderate to severe hepatic impairment.
Cedilanid-D (deslanoside) is a rapidly acting parenteral digitalis glycoside. Use with extreme caution in renal impairment due to reduced clearance. Monitor serum potassium and magnesium; hypokalemia and hypomagnesemia potentiate toxicity. Administer slow IV push over 5 minutes to avoid arrhythmias. Therapeutic drug monitoring less common due to short half-life of 33 hours. Contraindicated in ventricular tachycardia and AV block (unless due to atrial fibrillation).

SENSIPAR is a Calcimimetic that works by Calcimimetic agent that allosterically modulates the calcium-sensing receptor (Ca SR) on parathyroid chief cells, increasing its sensitivity to extracellular calcium, thereby reducing parathyroid hormone (PTH) secretion.. CEDILANID-D is a Cardiac Glycoside that works by Digitalis glycoside; inhibits Na+/K+-ATPase, increasing intracellular calcium and cardiac contractility.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between SENSIPAR and CEDILANID-D depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of SENSIPAR is: 30 mg orally once daily, titrated every 2-4 weeks to a maximum of 180 mg once daily to achieve target i PTH reduction.. The standard adult dose of CEDILANID-D is: 0.05 to 0.2 mg intravenously or intramuscularly, administered slowly over 5 minutes; initial dose 0.15 to 0.2 mg, then 0.1 to 0.15 mg every 30 minutes up to a total of 0.4 mg.

CEDILANID-D is classified as Category C. Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk.
