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 components of Axura tablets (see 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).

The treatment must be carefully supervised and your doctor must regularly reevaluate the clinical benefit of Axura.

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

Memantine should be avoided when used with other medications such as amantadine (for Parkinson's treatment), ketamine (a medication generally used for anesthesia), dextromethorphan (a medication for cough treatment) and other NMDA antagonists.

Children and adolescents

Do not recommend the use of Axura 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 the 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 at the start of use and should never be unscrewed.

How the dosifier works:

• Turn the dosifier head in the opposite direction to the clock to open
• Turn the dosifier head in the direction of the clock to close.

The dosifier head should 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 should 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 bottle provided, not for other products or containers. If the dosifier does not work correctly, consult your doctor or pharmacist. Close the dosifier after using Axura.
