Study Eligibility Criteria

Inclusion Criteria

The following inclusion criteria must be met for each subject:
* Paediatric subjects (\<12 years of age) with hyperkalaemia at screening.
* Subject's age should not reach 12 years during the 28 days of the pharmacodynamic (PD)/dose-ranging period.
* Subject is able to receive regular external feeding and medication, including via tubes, e.g., percutaneous endoscopic gastrostomy (PEG or entero-gastric feeding tube).
* At screening/baseline, the results from 2 separate and consecutive potassium assessments using the same measurement method (whole blood, plasma, or serum) need to be above the age-appropriate ULN.
* If taking any renin-angiotensin aldosterone system inhibitors (RAASi), beta blockers, fludrocortisone, or diuretic medications, must be on a stable dose for at least 14 days prior to screening.
* Parent(s) or legally authorised representative(s) or another appropriate person delegated by the legally authorised representatives must be available to help the study-site personnel ensure follow-up; accompany the participant to the study site on each assessment day; accurately and reliably dispense investigational product as directed.
* Females of child bearing potential must be non-lactating, must have a negative pregnancy test at screening, and must have used an effective, acceptable form of contraception (e.g., abstinence) for at least 1 month before patiromer administration. Females of child bearing potential must agree to continue using contraception throughout the study and for 1 month after the last dose of patiromer.

Exclusion Criteria

The following criteria exclude a subject from participating in this trial:
* Preterm birth infants with \<37 weeks of gestation cannot be included in Cohort 3.
* Participants who due to their general condition, e.g., anaemia or low body weight, are not suitable to have blood volume withdrawn.
* Any of the following renal conditions: maintenance haemodialysis or peritoneal dialysis, renal artery stenosis, and acute kidney injury (defined by 2012 Kidney Disease Improving Global Outcomes) or a history of acute renal insufficiency in the past 3 months. Note: Chronic kidney disease (CKD) is not excluded.
* A history of or current diagnosis of a severe gastrointestinal (GI) diagnosis or surgery that could affect GI transit of the drug (delayed gastric emptying), such as a severe swallowing disorder, severe gastroesophageal reflux, uncorrected pyloric stenosis, intussusception, any other intestinal obstruction (e.g., Hirschsprung disease, chronic intestinal pseudo-obstruction, clinically significant postsurgical abdominal adhesions) or any gut-shortening surgical procedure prior to screening. Pre-gastric above-mentioned pathologies may be disregarded in case of existence of a PEG or entero-gastric feeding tube, as the PEG or entero-gastric feeding tube will serve for nutrition and investigational product administration.
* Active cancer, currently on cancer treatment, or history of cancer in the past 2 years (except for non-melanoma skin cancer).
* Recipient of any organ transplant requiring treatment with immunosuppressive therapy or scheduled for kidney transplant procedure during the first 28 days after Day 1.
* History of sudden infant death in a sibling (only for participants \<2 years of age at screening).
* Use of the following medications if doses have not been stable for at least 14 days prior to screening or if doses are anticipated to change during the 4-week PD/ dose-ranging period: digoxin, bronchodilators, theophylline, heparins (including low molecular heparins), tacrolimus, mycophenolate mofetil, cyclosporine, trimethoprim, or cotrimoxazole.
* Use of any investigational product for an unapproved indication within 30 days prior to screening or within 5 half-lives, whichever is longer.
* Known hypersensitivity to patiromer or its components.
* If the child is being breastfed:
1. There is suspicion of current alcohol or substance misuse/abuse in breast
