Summary
Lactate is metabolized to bicarbonate and may alkalinize urine, reducing memantine clearance. The effect is usually smaller than with direct alkalinizers.
What this interaction means in plain words
Memantine and Sodium lactate can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Urinary alkalinization increases passive tubular reabsorption of memantine.
What to do
Monitor for confusion, dizziness or sedation when large lactate volumes are given, and adjust memantine if needed.
What to ask your pharmacist
