Cinacalcet 30 mg is an oral calcimimetic medicine used to lower high parathyroid hormone (PTH) levels and high calcium levels in the blood. It is mainly used in chronic kidney disease (CKD) patients on dialysis with secondary hyperparathyroidism, and in people with high calcium levels caused by parathyroid cancer or primary hyperparathyroidism when surgery is not possible. It works by making the parathyroid glands more sensitive to calcium, so they release less PTH, which helps lower calcium levels in the blood. Common side effects include nausea, vomiting, diarrhea, dizziness, weakness, loss of appetite, and chest pain.  

The most important serious side effect is low calcium levels (hypocalcemia), which can cause tingling, muscle cramps, seizures, fainting, or heart rhythm problems. It should usually be taken with food or shortly after a meal for better absorption and to reduce stomach upset.

Cinacalcet 30 mg is an oral medicine belonging to the category of calcimimetic medicine. Cinacalcet 30 mg is used to treat the following conditions: 

1. Secondary hyperparathyroidism 
2. High calcium levels in the blood (hypercalcemia)  

More Common  

1. Nausea  
2. Vomiting  
3. Diarrhea  
4. Dizziness  
5. Weakness / tiredness  
6. Loss of appetite  
7. Weight loss  
8. Chest pain             

Less Common 

1. Irregular heartbeat / fast or slow heartbeat  
2. Fainting or feeling like you may faint  
3. Trouble breathing / shortness of breath  
4. Severe allergic reaction (rash, swelling of face/lips/tongue, tight chest)  
5. Black stools or bloody vomit         

Cinacalcet 30 mg works by increasing the sensitivity of the parathyroid glands to calcium in the blood. 
As a result, the glands release less parathyroid hormones (PTH). Lower PTH levels help reduce high calcium levels in the blood. This is why cinacalcet is used in conditions where PTH and calcium levels are elevated, especially in kidney patients on dialysis and in parathyroid gland disorders. 

Allergy or Hypersensitivity

If you are allergic to Cinacalcet 30 mg, you should avoid it because it can cause serious allergic reactions like rash, itching, swelling, or breathing problems.

History of Seizures (Fits)

If you have a history of seizures or fits, use this medicine only if your doctor advises, because cinacalcet can lower calcium levels and low calcium may increase the risk of seizures.

Heart Rhythm Problems

If you have irregular heartbeat or other heart rhythm problems, this medicine should be used carefully because low calcium caused by cinacalcet may worsen heart rhythm issues.

Heart Disease / Heart Failure

If you have serious heart disease or heart failure, take this medicine only under medical supervision because changes in calcium levels may affect heart function.

Liver Problems

If you have liver disease, use this medicine carefully because the medicine may stay longer in the body, which can increase the chance of side effects.

Children

Cinacalcet is not usually recommended for children unless a specialist doctor advises it, because the risk of severe low calcium can be higher.

Low Calcium Levels (Hypocalcemia)

If you already have low calcium levels in the blood, you should not take cinacalcet because this medicine can lower calcium even more and may lead to serious problems like muscle cramps, tingling, seizures, or heart rhythm changes.

Cinacalcet 30 mg should be taken with food or shortly after a meal, because food helps the body absorb the medicine better and may also reduce stomach side effects like nausea or vomiting. It is best to avoid taking it on an empty stomach. Also, you should talk to your doctor before eating grapefruit or drinking grapefruit juice while taking cinacalcet, because it may affect how the medicine works in the body.

Avoid taking Cinacalcet 30 mg with the following medicines, as it may increase or decrease the desired effect, or in worse cases, it could be fatal:

IUPAC (International Union of Pure and Applied Chemistry)/ Chemical name

N-[(1R)-1-naphthalen-1-ylethyl]-3-[3-(trifluoromethyl)phenyl]propan-1-amine

What are the uses of Cinacalcet 30 mg? 

Cinacalcet 30 mg is used to lower high parathyroid hormone (PTH) levels and high calcium levels in the blood. It is mainly used in chronic kidney disease (CKD) patients with secondary hyperparathyroidism, and in people with high calcium levels due to parathyroid cancer or primary hyperparathyroidism.  

What is the drug class of Cinacalcet 30 mg? 

Cinacalcet 30 mg belongs to the class of medicines called calcimimetics. These medicines act by making the body respond to calcium more strongly, which helps lower parathyroid hormone (PTH).  

What is the mechanism of action (MOA) of Cinacalcet 30 mg? 

Cinacalcet 30 mg works by increasing the sensitivity of the parathyroid glands to calcium in the blood. As a result, the glands release less parathyroid hormone (PTH). Lower PTH levels help reduce high calcium levels in the blood and may also help lower phosphorus levels in some patients.  

What are the common side effects of Cinacalcet 30 mg? 

Common side effects of cinacalcet include nausea, vomiting, diarrhea, dizziness, weakness, and chest pain. Some people may also have loss of appetite or feel generally unwell.
