What are Hyperkalemia Drugs?
Hyperkalemia drugs are medications designed to reduce high potassium levels in the blood and prevent related cardiac complications. The hyperkalemia drugs market is growing due to the rising prevalence of chronic kidney disease, heart failure, and diabetes, all of which increase the risk of elevated potassium levels. Greater use of RAAS inhibitors in cardiovascular treatment is also driving demand for effective potassium-lowering therapies. Additionally, improved clinical awareness, advancements in novel potassium binders, and expanding access to outpatient management options are supporting wider adoption and market growth.
For Instance,
- In September 2025, AstraZeneca Pharma India gained approval from the Subject Expert Committee under CDSCO to begin a Phase IV trial of Sodium Zirconium Cyclosilicate (Lokelma) in India. The study will further evaluate the drug’s effectiveness and safety for treating hyperkalemia in real-world patients.
Market Growth
The hyperkalemia drugs market size was reported at US$ 1.42 billion in 2025 and is expected to rise to US$ 1.62 billion in 2026. According to forecasts, it will grow at a CAGR of 13.84% to reach US$ 5.20 billion by 2035.
