Sodium Zirconium Cyclosilicate (Lokelma) is a medication used to treat high potassium levels (hyperkalemia) in the blood. It works by binding to excess potassium in the digestive system and removing it from the body. This medication is particularly important for patients with chronic kidney disease who often struggle with maintaining normal potassium levels.

RAASi (Renin-Angiotensin-Aldosterone System inhibitors) are medications that help control blood pressure and protect kidney function. They are commonly used in patients with chronic kidney disease but may sometimes need to be discontinued if potassium levels become too high.

MRA (Mineralocorticoid Receptor Antagonists) are medications that help manage heart failure and high blood pressure by blocking certain hormones in the body. Like RAASi, these medications may need to be discontinued if a patient develops high potassium levels.

Hyperkalemia – A condition where there is too much potassium in the blood, specifically above normal levels (typically over 5.5 mEq/L). It commonly occurs in people who have chronic kidney disease, as their kidneys cannot effectively remove excess potassium from the body. The condition develops gradually as potassium builds up in the bloodstream. When kidneys are not functioning properly, they struggle to maintain the delicate balance of potassium needed for proper muscle and nerve function. Hyperkalemia can affect how the heart and other muscles work in the body.

Chronic Kidney Disease – A long-term condition where the kidneys gradually lose their ability to filter waste and excess fluid from the blood. The disease progresses through several stages, during which kidney function steadily declines. As the condition advances, various chemicals and waste products begin to build up in the blood. The kidneys become less effective at maintaining proper levels of minerals and nutrients in the body. This condition often develops slowly over months or years.
