Memantine oral solution belongs to a group of medicines known as anti-dementia medicines.
Memory loss in Alzheimer's disease is due to a disturbance of message signals in the brain. The brain contains so-called N-methyl-D-aspartate (NMDA)-receptors that are involved in transmitting nerve signals important in learning and memory.
Memantine oral solution belongs to a group of medicines called NMDA-receptor antagonists. Memantine oral solution acts on these NMDA-receptors improving the transmission of nerve signals and the memory.
Memantine oral solution is used for the treatment of patients with moderate to severe Alzheimer’s disease

The solution must not be poured or pumped directly into the mouth from the bottle or pump. Measure the dose onto a spoon or into a glass of water, using the pump.
The cap must be turned anticlockwise, unscrewed completely and removed (figure 1).
Take the dosing pump out of the plastic bag (figure 2) and place it on top of the bottle. Slide the plastic dip tube carefully into the bottle. Hold the dosing pump onto the neck of the bottle and screw it clockwise until it fits firmly (figure 3). The dosing pump is only screwed on once when starting the use, and should never be unscrewed.
The dosing pump head has two positions and is easy to turn:
The dosing pump head should not be pushed down while in the locked position. The solution may only be dispensed in the unlocked position. To unlock, turn the pump head in the direction of the arrow until it cannot be turned any further (figure 4). The dosing pump is then ready for use.
When used for the first time, the dosing pump does not dispense the correct amount of oral solution. Therefore, the pump must be prepared (primed) by pushing the dosing pump head down completely six times in succession (figure 5).
The solution thus dispensed is discarded. The next time the dosing pump head is pushed downwards completely (equivalent to one pump actuation), it dispenses the correct dose (figure 6).
Hold the bottle in a slightly tilted position.
Hold a glass with a little water or a spoon below the nozzle. Push down the dosing pump head in a firm but calm and steady manner - not too slowly (figure 7, figure 8).
The dosing pump head can then be released and is ready for the next pump actuation.
The dosing pump must only be used with the Memantine oral solution in the bottle provided, not for other substances or containers. If the pump does not function properly, consult your doctor or a pharmacist. Lock the dosing pump after using Memantine oral solution.
