Lokelma is a tablet used to treat high blood potassium levels.
Lokelma is the brand name for sodium zirconium cyclosilicate, a type of medicine known as a potassium binder.
It is not a blood pressure medication or a “water tablet,” but it is often used alongside them.
People with:
Hyperkalaemia: High levels of potassium in the blood.
Chronic Kidney Disease (CKD): Since the kidneys normally filter out excess potassium, patients with CKD often develop dangerously high levels.
Heart Failure: It allows patients to continue taking life-saving medications (like ACE inhibitors or Spironolactone) that tend to raise potassium as a side-effect.
Initial “Loading” Phase: Usually 10 g three times a day for up to 48 hours to bring high levels down quickly.
Maintenance Phase: Once the potassium is stable, the dose is usually 5 g to 10 g once a day.
It comes as a powder in a sachet that you mix with about 45 ml (3 tablespoons) of water. It does not dissolve, so you must drink the cloudy mixture immediately.
Oedema (Swelling): Because Lokelma contains sodium, some patients may experience fluid retention or swelling in the ankles and legs.
Hypokalaemia: If the dose is too high, potassium levels can drop too low.
Constipation or Diarrhoea: Changes in bowel habits can occur as the medicine works in the gut.
Lokelma works in the digestive tract (stomach and intestines).
It acts like a highly selective “sponge” that traps potassium from food and digestive juices, preventing it from being absorbed into the bloodstream.
The trapped potassium is then passed out of the body in the stool, effectively lowering the potassium levels in the blood.
Your doctor should monitor:
Blood potassium levels: Frequently at first, then at regular intervals during long-term treatment.
Signs of fluid overload: Checking for swelling or sudden weight gain.
Note: Lokelma can affect how other oral medicines are absorbed. You should generally take other medications at least 2 hours before or 2 hours after taking Lokelma.
