Cinacalcet (30mg).

Jun 12, 2023

Calcium imbalance and parathyroid disorders are increasingly diagnosed in India, especially among patients with chronic kidney disease (CKD) and those on long-term dialysis. Conditions such as secondary hyperparathyroidism and hypercalcaemia can silently damage bones, blood vessels, and vital organs if not managed properly.

CINASELECT 30 Tablet, containing Cinacalcet 30 mg, is a clinically proven medicine used to control abnormal parathyroid hormone (PTH) levels and maintain healthy calcium balance in the body.

This comprehensive guide explains everything you need to know about CINASELECT 30, including its composition, mechanism of action, uses, benefits, dosage, side effects, precautions, and frequently asked questions.

Introduction to CINASELECT 30

CINASELECT 30 is a prescription medicine formulated with Cinacalcet Hydrochloride 30 mg, a calcimimetic agent that plays a key role in regulating parathyroid hormone secretion. It is widely prescribed in nephrology and endocrinology to manage:

  • Secondary hyperparathyroidism in chronic kidney disease

  • Hypercalcaemia due to parathyroid disorders

  • Parathyroid carcinoma (in select cases)

By lowering excessive PTH levels, CINASELECT 30 helps protect bones, prevent calcium deposition in blood vessels, and reduce long-term complications associated with mineral imbalance.

Composition of CINASELECT 30

Each tablet contains:

  • Cinacalcet 30 mg

Cinacalcet is a selective calcium-sensing receptor (CaSR) modulator that mimics the action of calcium on the parathyroid gland.

What is Cinacalcet?

Cinacalcet is a calcimimetic agent, meaning it increases the sensitivity of calcium-sensing receptors present on parathyroid cells. This enhanced sensitivity leads to reduced secretion of parathyroid hormone, thereby helping control calcium and phosphorus levels in the blood.

Unlike calcium supplements or vitamin D analogues, Cinacalcet directly targets the parathyroid gland, making it highly effective in conditions where PTH levels are excessively high.

How CINASELECT 30 Works

The parathyroid glands regulate calcium levels by releasing parathyroid hormone. In certain conditions, these glands become overactive, leading to high PTH levels.

CINASELECT 30 works by:

  • Increasing the sensitivity of calcium-sensing receptors

  • Reducing excess parathyroid hormone secretion

  • Lowering serum calcium and phosphorus levels

  • Preventing bone resorption and vascular calcification

This targeted mechanism makes CINASELECT 30 especially valuable in dialysis patients and those with parathyroid disorders.

Uses of CINASELECT 30 Tablet

1. Secondary Hyperparathyroidism in Chronic Kidney Disease

CINASELECT 30 is primarily used in patients with CKD, especially those undergoing dialysis, to:

  • Reduce elevated PTH levels

  • Prevent bone pain and fractures

  • Control calcium-phosphorus imbalance

2. Hypercalcaemia

Used to manage high calcium levels caused by:

  • Parathyroid adenoma

  • Parathyroid carcinoma

  • Primary hyperparathyroidism (when surgery is not suitable)

3. Parathyroid Carcinoma

Helps control severe hypercalcaemia associated with parathyroid cancer.

CINASELECT 30 Dosage

Recommended Dose

  • Usually one tablet once daily

  • Dose may be adjusted based on PTH and calcium levels

How to Take

  • Take with food or immediately after meals

  • Swallow the tablet whole with water

  • Do not crush or chew

Dose Adjustment

Regular blood tests are required to monitor:

  • Serum calcium

  • Phosphorus

  • Parathyroid hormone levels

Dose adjustments should only be made by a healthcare professional.

Missed Dose and Overdose

Missed Dose

  • Take it as soon as you remember

  • Skip the dose if it’s close to the next one

  • Do not double the dose

Overdose

Overdose may cause dangerously low calcium levels. Seek immediate medical attention if symptoms such as muscle cramps, tingling, or seizures occur.

Side Effects of CINASELECT 30

Like all medicines, CINASELECT 30 may cause side effects, though not everyone experiences them.

Common Side Effects

  • Nausea

  • Vomiting

  • Loss of appetite

  • Diarrhoea

Less Common Side Effects

  • Muscle pain

  • Dizziness

  • Weakness

Serious Side Effects (Rare)

  • Hypocalcaemia (low calcium levels)

  • Muscle spasms or cramps

  • Tingling in hands, feet, or lips

Immediate medical attention is required if severe symptoms occur.

Precautions and Warnings

Low Calcium Levels

CINASELECT 30 should not be started if calcium levels are already low.

Seizure Disorders

Low calcium may increase seizure risk; use cautiously.

Heart Conditions

Abnormal calcium levels can affect heart rhythm; regular monitoring is essential.

Pregnancy and Breastfeeding

Use only if clearly advised by a doctor.

Pediatric Use

Not recommended unless prescribed by a specialist.

Drug Interactions

CINASELECT 30 may interact with:

  • Calcium supplements

  • Vitamin D analogues

  • Certain antifungal medicines

  • Anti-seizure medications

Always inform your doctor about all medicines and supplements you are taking.
