May 2018 FDA New Drug Approvals
1. A MONTHLY
DOSE OF EDUCATION

CEO, A Dose of Education, LLC
May 2018
2. FDA Approval
• Lokelma® (sodium zirconium cyclosilicate) – approved 5/18/18
• A potassium binder indicated for the treatment of hyperkalemia in adults
• Formulation and Administration:
• For oral suspension: 5 g per packet or 10 g per packet
• Recommended starting dose is 10 g administered three times a day for
up to 48 hours
• For maintenance treatment, recommended dose is 10 g once daily (can
range from 5 g every other day to 15 g daily)

https://www.accessdata.fda.gov/drugsatfda_docs/label/2018/207078s000lbl.pdf
3. Lokelma® (sodium zirconium cyclosilicate)
• Warning/Precautions:
• Gastrointestinal Adverse Events in Patients with Motility Disorders.
• Edema
• Adverse Reactions:
• Most common is mild to moderate edema
• Drug Interactions:
• In general, other oral medications should be administered at least 2
hours before or 2 hours after
https://www.accessdata.fda.gov/drugsatfda_docs/label/2018/207078s000lbl.pdf
4. Lokelma® (sodium zirconium cyclosilicate)
• Reconstitution:
• Instruct patients to empty the entire contents of the packet(s) into a
drinking glass containing approximately 3 tablespoons of water or more if
desired. Stir well and drink immediately. If powder remains in the
drinking glass, add water, stir and drink immediately. Repeat until no
powder remains to ensure the entire dose is taken.
• Mechanism of Action:
• Preferentially captures potassium in exchange for hydrogen and sodium.
In vitro, has a high affinity for potassium ions, even in the presence of
other cations such as calcium and magnesium.
• Increases fecal potassium excretion through binding of potassium in the
lumen of the gastrointestinal tract. Binding of potassium reduces the
concentration of free potassium in the gastrointestinal lumen, thereby
lowering serum potassium levels.
