Sodium Zirconium Cyclosilicate
Generic Name: sodium zirconium cyclosilicate
Brand Names:
Lokelma
11 DESCRIPTION LOKELMA is a powder for oral suspension. The active ingredient in LOKELMA is sodium zirconium cyclosilicate, a potassium binder. Sodium zirconium cyclosilicate is a non-absorbed zirconium silicate that preferentially exchanges potassium for hydrogen and sodium. LOKELMA is an odorless, insoluble white to grey powder for oral suspension. It has a mean particle size of 20 µm and includes no more than 3% of particles with a diameter below 3 µm.

Uses
1 INDICATIONS AND USAGE LOKELMA is indicated for the treatment of hyperkalemia in adults. Limitation of Use LOKELMA should not be used as an emergency treatment for life-threatening hyperkalemia because of its delayed onset of action [see Clinical Pharmacology (12.2) and Clinical Studies (14) ] . LOKELMA is a potassium binder indicated for the treatment of hyperkalemia in adults. ( 1 ) Limitation of Use LOKELMA should not be used as an emergency treatment for life-threatening hyperkalemia because of its delayed onset of action. ( 1 )
Dosage
2 DOSAGE AND ADMINISTRATION • Recommended starting dose is 10 g administered three times a day for up to 48 hours. ( 2.1 ) • For maintenance treatment, recommended dose is 10 g once daily. Adjust dose at one-week intervals as needed (by 5 g daily) to obtain desired serum potassium target range. ( 2.1 ) Patients on Chronic Hemodialysis • Recommended starting dose is 5 g once daily on non-dialysis days. ( 2.2 ) See full Prescribing Information for additional dosing instructions, as well as reconstitution and administration instructions for the oral suspension. 2.1 Recommended Dosage For initial treatment of hyperkalemia, the recommended dose of LOKELMA is 10 g administered three times a day for up to 48 hours.
Side Effects
6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail elsewhere in the label: • Edema [see Warnings and Precautions (5.2) ] . Most common adverse reactions with LOKELMA: mild to moderate edema. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AstraZeneca at 1-800-236-9933 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
Interactions
7 DRUG INTERACTIONS LOKELMA can transiently increase gastric pH. As a result, LOKELMA can change the absorption of co-administered drugs that exhibit pH-dependent solubility, potentially leading to altered efficacy or safety of these drugs when taken close to the time LOKELMA is administered. In general, other oral medications should be administered at least 2 hours before or 2 hours after LOKELMA [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ] . LOKELMA is not expected to impact systemic exposure of drugs that do not exhibit pH-dependent solubility and so spacing is not needed if it has been determined that the concomitant medication does not exhibit pH-dependent solubility.
Warnings
5 WARNINGS AND PRECAUTIONS • Gastrointestinal Adverse Events in Patients with Motility Disorders. ( 5.1 ) • Edema. ( 5.2 ) • Hypokalemia in patients on hemodialysis. ( 5.3 ) • LOKELMA has radio-opaque properties and, therefore, may give the appearance typical of an imaging agent during abdominal X-ray procedures. ( 5.4 ) 5.1 Gastrointestinal Adverse Events in Patients with Motility Disorders Avoid use of LOKELMA in patients with severe constipation, bowel obstruction or impaction, including abnormal post-operative bowel motility disorders, because LOKELMA has not been studied in patients with these conditions and may be ineffective and may worsen gastrointestinal conditions. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary LOKELMA is not absorbed systemically following oral administration and maternal use is not expected to result in fetal exposure to the drug.
