Calcium Polystyrene Sulfonate 99.934% w/w Powder for Oral/Rectal Suspension

What it is and what it is used for

Calcium Polystyrene Sulfonate 99.934% w/w powder for Oral/Rectal suspension (called Calcium Polystyrene Sulfonate powder in this leaflet) contains the active substance calcium polystyrene sulfonate. This belongs to a group of medicines called 'ion exchange resins'.

Calcium Polystyrene Sulfonate powder is used when you have too much potassium in your blood, a condition called 'hyperkalaemia'. It works by removing this extra potassium to bring your levels back to normal. It is often given to people who have kidney problems and people on dialysis.

What you need to know before you take it

Do not use Calcium Polystyrene Sulfonate powder and tell your doctor, pharmacist or nurse if: • you are allergic to calcium polystyrene sulfonate or any of the other ingredients of this medicine (listed in section 6)
• you have a condition where the body fluids and tissues are unusually alkaline (metabolic or respiratory alkalosis)
• you have low levels of potassium in your blood
• you have a condition which results in high levels of calcium such as problems with your thyroid or some types of cancer
• your gut is blocked (obstructive bowel disease).
Warnings and precautions Talk to your doctor, pharmacist or nurse before taking Calcium Polystyrene Sulfonate powder if:

• you are taking or using sorbitol, a sugar free sweetener used in food and drink. You must not take any sorbitol whilst using Calcium Polystyrene Sulfonate powder.
• it is for your baby, and they were premature, had a low birth-weight or have reduced gut movement.
• you suffer with constipation.
• you have abnormal bowel movements due to your medical condition (including conditions after surgery or drug usage) as these may cause a variety of disorders including bloating, severe constipation, reduced blood supply to your gut or ruptured bowel.
Your doctor will monitor the balance of your, or your child's electrolytes in your body while using Calcium Polystyrene Sulfonate powder.

Children Do not give this medicine by mouth to babies up to four weeks old. Administration by the rectum (back passage) must be carefully considered by your doctor (see Section3).

⚕For healthcare professionals — Summary of Product Characteristics (SmPC)Full SmPC: dosage, interactions, contraindications, warnings+
Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Calcium Polystyrene Sulfonate is an ion-exchange resin that is recommended for the treatment of hyperkalaemia associated with anuria or severe oliguria. It is also used to treat hyperkalaemia in patients requiring dialysis and in patients on regular haemodialysis or on prolonged peritoneal dialysis.

4.2. Posology and method of administration

Calcium Polystyrene Sulfonate is for oral or rectal administration only.

The dosage recommendations detailed below are a guide only; the precise requirements should be decided on the basis of regular serum electrolyte determinations.

Adults, including the elderly:

Oral

The usual dose is 15g three or four times a day. Each dose should be given as a suspension in a small amount of water or, for greater palatability, in syrup (but not fruit juices which contain potassium), in the ratio of 3 to 4ml per gram of resin.

Administer Calcium Polystyrene Sulfonate at least 3 hours before or 3 hours after other oral medications. For patients with gastroparesis, a 6 hour separation should be considered.

Rectal

This route should be reserved for the patient who is vomiting or who has upper gastrointestinal tract problems, including paralytic ileus. It may be used simultaneously with the oral route for more rapid initial results or in patients with gastroparesis, who have other orally administered medications that are administered within 6 hours of Calcium Polysterene Sulfonate. The resin may be given rectally as a suspension of 30g resin in 150ml of water or 10% dextrose, as a daily retention enema. In the initial stages administration by this route as well as orally may help to achieve a rapid lowering of the serum potassium level.

The enema should if possible be retained for a least nine hours, then the colon should be irrigated to remove the resin. If both routes are used initially it is probably unnecessary to continue rectal administration once the oral resin has reached the rectum.

Children:

Oral

In smaller children and infants correspondingly smaller doses should be employed by using as a guide a rate of 1mEq of potassium per gram of resin as the basis for calculation. An appropriate initial dose is 1g/kg body weight daily in divided doses, in acute hyperkalaemia. Dosage may be reduced to 0.5g/kg body weight daily in divided doses for maintenance therapy. The resin is given orally, preferably with a drink (not a fruit squash because of the high potassium content) or a little jam or honey.

Rectal

When refused by mouth it should be given rectally using a dose at least as great as that which would have been given orally, diluted in the same ratio as described for adults. Following retention of the enema, the colon should be irrigated to ensure adequate removal of the resin.

Neonates:

Calcium Polystyrene Sulfonate should not be given by the oral route. With rectal administration, the minimum effective dosage within the range 0.5g/kg to 1g/kg should be employed, diluted as for adults with adequate irrigation to ensure recovery of the resin.

4.3. Contraindications

• In patients with plasma potassium levels below 5mmol/litre.

• Conditions associated with hypercalcaemia (e.g. hyperparathyroidism, multiple myeloma, sarcoidosis or metastatic carcinoma).

• History of hypersensitivity to polystyrene sulfonate resins.

• Obstructive bowel disease.

• Calcium Polystyrene Sulfonate should not be administered orally to neonates and is contraindicated in neonates with reduced gut motility (post-operatively or drug induced).

• Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

4.5. Interaction with other medicinal products and other forms of interaction

Orally administered medications: Calcium Polystyrene Sulfonate has the potential to bind to other orally administered medications. Binding of Calcium Polystyrene Sulfonate to other oral medications could cause decrease in their gastrointestinal absorption and efficacy. Dosing separation of Calcium Polystyrene Sulfonate from other orally administered medications is recommended.

Concomitant use not recommended Sorbitol (oral or rectal): Concomitant use of Sorbitol with calcium polystyrene sulfonate is not recommended due to cases of intestinal necrosis and other serious gastrointestinal adverse reactions, which may be fatal (see Section 4.4 Special warnings and precautions for use and Section 4.8 Undesirable effects).

To be used with caution

Cation-donating agents: may reduce the potassium binding effectiveness of Calcium Polystyrene Sulfonate.

Non-absorbable cation-donating antacids and laxatives: There have been reports of systemic alkalosis following concurrent administration of cation-exchange resins and non-absorbable cation-donating antacids and laxatives such as magnesium hydroxide and aluminium carbonate.

Aluminium hydroxide: Intestinal obstruction due to concretions of aluminium hydroxide has been reported when aluminium hydroxide has been combined with the resin (sodium form).

Digitalis-like drugs: The toxic effects of digitalis on the heart, especially various ventricular arrhythmias and A-V nodal dissociation, are likely to be exaggerated if hypokalaemia and/or hypercalcaemia are allowed to develop (see section 4.4 Special warnings and precautions for use).

Lithium: Possible decrease of lithium absorption.

Levothyroxine: Possible decrease of levothyroxine absorption.

4.6. Fertility, pregnancy and lactation

Pregnancy

There are no or limited data from the use of Calcium Polystyrene Sulfonate in pregnant women. Animal studies are insufficient with respect to reproductive toxicity (see section 5.3).

Calcium Polystyrene Sulfonate is not recommended during pregnancy.

Breast-feeding

It is unknown whether Calcium Polystyrene Sulfonate metabolites are excreted in human milk. A risk to newborns/infants cannot be excluded.

A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from Calcium Polystyrene Sulfonate therapy taking into account the benefit of breast-feeding for the child and the benefit of treatment for the woman.

Fertility

There are no or limited data from the use of Calcium Polystyrene Sulfonate in fertility.

4.7. Effects on ability to drive and use machines

There are no specific warnings.

4.9. Overdose

Biochemical disturbances from overdosage may give rise to clinical signs or symptoms of hypokalaemia, including irritability, confusion, delayed thought processes, muscle weakness, hyporeflexia and eventual paralysis. Apnoea may be a serious consequence of this progression. Electrocardiographic changes may be consistent with hypokalaemia or hypercalcaemia; cardiac arrhythmia may occur. Appropriate measures should be taken to correct serum electrolytes and the resin should be removed from the alimentary tract by appropriate use of laxatives or enemas.
