Calcium Polystyrene Sulphonate Powder: Mechanism of Action and Side Effects.
Mar 03, 2025
Polystern Sachet contains Calcium Polystyrene Sulphonate Powder, a widely used medication for managing hyperkalemia (high potassium levels). This ion-exchange resin plays a vital role in maintaining electrolyte balance in patients suffering from chronic kidney disease (CKD), acute renal failure, Addison’s disease, or medication-induced potassium retention.
Hyperkalemia is a potentially life-threatening condition that can cause cardiac arrhythmias, muscle paralysis, and even sudden cardiac arrest. Calcium Polystyrene Sulphonate removes excess potassium from the body by exchanging calcium ions for potassium ions in the intestines, preventing severe complications.
This article provides an in-depth guide on Polystern Sachet, including uses, dosage, benefits, side effects, precautions, price in India, dietary recommendations, and alternative treatments.
Key Ingredient: Calcium Polystyrene Sulphonate
The active ingredient in Polystern Sachet is Calcium Polystyrene Sulphonate, a cation-exchange resin from the sulfonated polystyrene group. It has a strong affinity for potassium and is highly effective in lowering potassium levels in the blood.
Key Properties:
-
Cation-exchange resin that replaces potassium with calcium in the gastrointestinal tract
-
Works primarily in the large intestine
-
Gradually reduces potassium levels over several hours
-
Can be administered orally or rectally (enema) for severe cases
-
Commonly used for chronic kidney disease (CKD), dialysis patients, and hyperkalemia caused by medications
Uses of Polystern Sachet
Polystern Sachet is prescribed primarily for managing hyperkalemia in various medical conditions, including:
1. Chronic Kidney Disease (CKD)
Patients with CKD have reduced potassium excretion, leading to dangerously high potassium levels. Calcium Polystyrene Sulphonate gradually removes potassium, preventing further complications.
2. Acute Kidney Injury (AKI)
In cases of sudden kidney failure, potassium excretion is compromised. This medication helps prevent severe hyperkalemia-related complications.
3. Hyperkalemia Due to Medications
Certain drugs, such as ACE inhibitors, potassium-sparing diuretics, NSAIDs, and beta-blockers, increase potassium levels. Polystern Sachet counteracts this potassium buildup.
4. Addison’s Disease
In Addison’s disease, the adrenal glands fail to produce enough hormones, causing excess potassium retention. Polystern Sachet helps regulate potassium levels in such cases.
5. Heart Conditions & Arrhythmias
High potassium levels can trigger dangerous arrhythmias and cardiac issues. This powder is used as a preventive measure for heart patients.
6. Post-Dialysis Potassium Management
Patients on dialysis may experience potassium fluctuations. Polystern Sachet helps maintain safe potassium levels between dialysis sessions.
7. Liver Cirrhosis with Hyperkalemia
Liver disease can lead to electrolyte imbalances, including hyperkalemia. This medication helps regulate potassium levels in such conditions.
Dosage & Administration
The dosage of Polystern Sachet depends on hyperkalemia severity, kidney function, and the patient’s overall health condition. It should always be taken under medical supervision.
Recommended Dosage:
-
Adults: 15 g (one sachet) 1 to 4 times daily
-
Children: 0.5 g per kg of body weight 1 to 4 times daily
-
Neonates (Newborns): 0.5 g per kg divided into multiple doses
How to Use:
-
The powder should be mixed with water or soft food like yogurt or honey before consumption.
-
Take this medicine 1-3 hours before or after meals for maximum effectiveness.
-
For severe cases, it can be administered rectally (enema) under medical supervision.
Key Benefits of Polystern Sachet
1. Effective Potassium Reduction
-
Helps maintain safe potassium levels in patients with kidney disease.
-
Prevents life-threatening cardiac arrhythmias due to hyperkalemia.
2. Non-Sodium Formula
-
Unlike Sodium Polystyrene Sulfonate, which can increase sodium levels and worsen hypertension, Calcium Polystyrene Sulphonate does not contribute to sodium overload.
3. Easy to Use & Convenient
-
Available in sachet form, making it easy to mix and consume.
-
Can be administered orally or rectally.
4. Helps Avoid Emergency Dialysis
-
Provides an alternative to dialysis in mild to moderate hyperkalemia cases.
