How Axura works

Axura contains the active ingredient memantine hydrochloride.

Axura belongs to a group of medications known as dementia medications.

Memory loss in Alzheimer's disease is due to an alteration in brain signals. The brain contains called N-methyl-D-aspartate (NMDA) receptors that participate in the transmission of important nerve signals in learning and memory. Axura belongs to the group of medications called NMDA receptor antagonists. Axura acts on these receptors by improving the transmission of nerve signals and memory.

When is Axura used

Axura is used in the treatment of patients with moderate to severe Alzheimer's disease.

Do not take Axura

• if you are allergic (hypersensitive) to memantine hydrochloride or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Consult your doctor or pharmacist before starting to take Axura

• if you have a history of epileptic seizures (convulsions)
• if you have recently had a myocardial infarction (heart attack), if you suffer from congestive heart failure or if you have uncontrolled hypertension (high blood pressure).

In the above situations, treatment should be closely monitored and your doctor should regularly reevaluate the clinical benefit of Axura.

If you have renal insufficiency (kidney problem), your doctor should closely monitor renal function and, if necessary, adapt memantine doses.

Memantine should be avoided when used with other medicines such as amantadine (for Parkinson's treatment), ketamine (a general anesthetic), dextromethorphan (a cough medicine) and other NMDA antagonists.

Children and adolescents

Axura is not recommended for use in children and adolescents under 18 years.

Instructions for the correct use of the dosifier

The solution must not be poured or dispensed directly into the mouth from the bottle or dosifier. Measure the dose in a spoon or in a glass of water using the dosifier.

Removing the cap from the bottle:

The cap must be turned in the opposite direction to the clock, unscrewed completely, and removed (fig. 1).

Mounting the dosifier on the bottle:

Remove the dosifier from the plastic bag (fig. 2) and place it on top of the bottle. Carefully insert the plastic tube into the bottle. Hold the dosifier on the bottle neck and turn it clockwise until it is securely attached (fig. 3). The dosifier should only be screwed on once when starting use and should never be unscrewed.

How the dosifier works:

The dosifier head has two positions and can be easily turned

• in the opposite direction to the clock to open
• in the direction of the clock to close.

The dosifier head must not be pressed down while it is in the closed position. The solution can only be dispensed in the open position. To open, turn the dosifier head in the direction indicated by the arrow until it cannot be turned any further (about one-eighth of a turn, fig. 4). The dosifier is then ready for use.

Preparing the dosifier.

When used for the first time, the dosifier does not dispense the correct amount of oral solution. Therefore, it must be prepared (primed) by pressing the dosifier head down completely five times in a row (fig. 5).

The solution dispensed in this way must be discarded. The next time the dosifier head is pressed down completely (equivalent to one press), it will already dispense the correct dose (fig. 6)

Correct use of the dosifier.

Place the bottle on a flat, horizontal surface, for example on a table, and it should only be used in an upright position. Place a glass with a little water or a spoon under the nozzle. Press the dosifier head down firmly but calmly and sustainably-not too slowly (fig. 7, fig. 8).

The head can then be released and is ready for the next press.

The dosifier should only be used with Axura solution in the provided bottle, not for other products or containers. If the dosifier does not work correctly, consult your doctor or pharmacist. Close the dosifier after using Axura.
