Memantine in published research
Reisberg and colleagues reported in NEJM (2003) a benefit in moderate to severe Alzheimer’s.
It’s a standard research tool for NMDA signaling.
Because it blocks the NMDA channel only when it’s open for a long time, it leaves normal signaling mostly intact.

Working with Memantine in solution
Memantine liquid is pre-dissolved at 10mg/mL, which makes measuring simple: you work in volumes instead of weighing tiny amounts of powder.
Use a clean graduated pipette or dropper for each draw so nothing goes back into the bottle. Shake gently first, because some solutions settle over time. We stock transfer pipettes and dropper bottles if you need them.
Making working dilutions of Memantine
If your protocol calls for a lower concentration, dilute a measured volume into a clean glass bottle. For example, 1mL of the 10mg/mL solution plus 1mL of carrier gives 2mL at 5mg/mL. Use the same carrier where possible, or a solvent your protocol allows, and mix gently.
Make up only what you’ll use in the short term, and label the new bottle with the concentration and date.
How we test Memantine
Every batch of Memantine is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
Storage and handling
Keep it in a cool, dry place away from direct sunlight. Keep the cap tight so the solution doesn’t evaporate or pick up contaminants. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
