    Dosage

    The recommended starting dose is 8.4 g patiromer once daily.
    The daily dose may be adjusted in intervals of one week or longer, based on the serum potassium level and the desired target range.
    The daily dose may be increased or decreased by 8.4 g as necessary to reach the desired target range, up to a maximum dose of 25.2 g daily.
    If serum potassium falls below the desired range, the dose should be reduced or discontinued.
    If a dose is missed, the missed dose should be taken as soon as possible on the same day. The missed dose should not be taken with the next dose.
    Administration be separated by 3 hours from other oral medicinal products.
    The onset of action of Patiromer occurs 4-7 hours after administration. Patiromer should not replace emergency treatment for life-threatening hyperkalaemia.
    Patients on dialysis: There is limited data on the use of Patiromer in patients on dialysis. No special dose and administration guidelines were applied to these patients in clinical studies.
    Elderly population (≥65 years of age): No special dose and administration guidelines are recommended for this population.
    Paediatric population: The safety and efficacy of Patiromer in children aged under 18 years have not yet been established. No data are available.
    Method of administration: Oral use. Patiromer should be mixed with water and stirred to a suspension of uniform consistency, according to the following steps:
    The complete dose should be poured into a glass containing approximately 40 ml of water, then stirred. Another approximately 40 ml of water should be added, and the suspension stirred again thoroughly. The powder will not dissolve. More water may be added to the mixture as needed for desired consistency.
    The mixture should be taken within 1 hour of initial suspension. If powder remains in the glass after drinking, more water should be added and the suspension stirred and taken immediately. This may be repeated as needed to ensure the entire dose is administered.
    Apple juice or cranberry juice can be used instead of water to prepare the mixture. Other liquids should be avoided as they may contain high amounts of potassium.
    In general, cranberry juice intake should be limited to moderate amounts (for example less than 400 ml per day) due to its potential interaction with other medicinal products.
    Patiromer should be taken with food. It should not be heated (e.g. microwaved) or added to heated foods or liquids. It should not be taken in its dry form.


    Indications

    Treatment of hyperkalaemia in adults.


    Contra-Indications

    Hypersensitivity to the active substance or to any of the excipients.


    Special Precautions

    Low Magnesium: In clinical studies, serum magnesium values <1.4 mg/dL (0.58 mmol/L) occurred in 9% of patients treated with Patiromer. Mean decreases in serum magnesium were 0.17 mg/dL (0.070 mmol/L) or less.
    Hypomagnesemia may occur during treatment. Monitoring of serum magnesium should be performed at the beginning of treatment, at appropriate intervals at least 1 month after initiating treatment, and at any clinical need.
    Gastrointestinal Disorders: Patients with a history of bowel obstruction or major gastrointestinal surgery, severe gastrointestinal disorders, or swallowing disorders were not included in the clinical studies. Gastrointestinal ischaemia, necrosis and/or intestinal perforation have been reported with other potassium binders. The benefits and risks of administering Patiromer should be carefully evaluated in patients with current or history of severe gastrointestinal disorders, before and during treatment.
    Discontinuation: When discontinuing Patiromer, serum potassium levels may rise, especially if RAAS inhibitor treatment is continued. Patients should be instructed not to discontinue therapy without consulting their physicians. Increases in serum potassium may occur as early as 2 days after the last Patiromer dose.
    Serum potassium levels: Serum potassium should be monitored when clinically indicated, including after changes are made to medicinal products that affect the serum potassium concentration (e.g. RAAS inhibitors or diuretics) and after the Patiromer dose is titrated.
    Information about sorbitol: Patiromer contains sorbitol as part of the counterion complex. The sorbitol content is approximately 4 g (10.4 kcal) per 8.4 g of patiromer.
    Patients with rare hereditary problems of fructose intolerance should not take this medicine.
    Information about calcium: Patiromer contains calcium as part of the counterion complex. Calcium is partially released some of which may be absorbed. The benefits and risks of administering this medicinal product should be carefully evaluated in patients at risk of hypercalcaemia.
    Limitations of the clinical data
    Patients with end-stage renal disease (ESRD): Patiromer has been studied only in a limited number of patients with estimated glomerular filtration rate (eGFR) <15 ml/min/1.73 m2 and patients receiving dialysis treatment.
    Data regarding efficacy and safety in end stage renal disease CKD-5 and patients on dialysis is limited.
    Severe hyperkalaemia: There is limited experience in patients with serum potassium concentrations greater than 6.5 mmol/L.
    Long term exposure: Clinical trials with Patiromer have not included exposure longer than one year.
    See prescribing information for full details.


    Side Effects

    Most common: Gastrointestinal disorders, with the most frequently reported ARs being constipation, diarrhoea, abdominal pain, flatulence, hypomagnesaemia.
    See prescribing information for full details.


    Drug interactions

    Patiromer has the potential to bind some oral co-administered medicinal products, which could decrease their gastrointestinal absorption.
    As precautionary measure, and based on the data summarised below, administration of Patiromer should therefore be separated by at least 3 hours from other oral medicinal products.
    Concomitant administration of Patiromer showed reduced bioavailability of ciprofloxacin, levothyroxine and metformin. However, there was no interaction when Patiromer and these medicinal products were taken 3 hours apart.
    In vitro studies have shown potential interaction of Patiromer with quinidine.
    Concomitant administration of Patiromer did however not affect the bioavailability as measured by the area under the curve (AUC) of amlodipine, cinacalcet, clopidogrel, furosemide, lithium, metoprolol, trimethoprim, verapamil and warfarin.
    In vitro studies have shown no potential interaction of Patiromer with the following active substances: allopurinol, amoxicillin, apixaban, acetylsalicylic acid, atorvastatin, cephalexin, digoxin, glipizide, lisinopril, phenytoin, riboflavin, rivaroxaban, spironolactone and valsartan.
    No clinical data is available for the concomitant treatment with phosphate binders. In vitro data indicates that probably there is no interaction.
    See prescribing information for full details.


    Pregnancy and Lactation

    Pregnancy: There are no data from the use of patiromer in pregnant women.
    LactationNo effects on the breast-fed newborn/infant are anticipated since the systemic exposure of the breast-feeding woman to patiromer is negligible. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from patiromer therapy taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman.
    See prescribing information for full details.


    Overdose

    Since excessive doses of Patiromer may result in hypokalaemia, serum potassium levels should be monitored. Patiromer is excreted after approximately 24 to 48 hours, based on average gastrointestinal transit time. If it is determined that medical intervention is required, appropriate measures to restore serum potassium may be considered.


    Important notes

    Storage: Store and transport refrigerated (2°C – 8°C). Patients may store Patiromer below 25°C for up to 6 months. For either storage condition, Patiromer should not be used after the expiry date printed on the sachet. The mixture should be taken within 1 hour of initial suspension.
