Sodium zirconium cyclosilicate
Administration[1]
- Type: Potassium binder, antidote
- Dosage Forms: 5 g (1 ea, 30 ea); 10 g (1 ea, 30 ea), empty contents into glass with 45 mL of water
- Routes of Administration: Oral
- Common Trade Names: Lokelma
Adult Dosing

Adverse Reactions
Serious
Common
- Mild to moderate edema
- Hypokalemia
Pharmacology
- Metabolism: none
- Excretion: feces
Mechanism of Action
- Highly selective, oral potassium removing agent
- Non-absorbed zirconium silicate that captures potassium in exchange for hydrogen and sodium
- Increases fecal potassium excretion through binding K+ in GI tract
Comments
- Onset of action at 1.0 hour and median time to achieving normal potassium levels at 2.2 hours, with 92% achieving normal potassium within 48 hours.
- Not used as an emergency treatment for life threatening hyperkalemia due to delayed onset of action
- Available at Harbor-UCLA, but not yet widely available in the community
- If asked by nephrology to give Kayexalate, kindly suggest Lokelma instead
