What is Memantina Stada used for

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

How Memantina Stada works

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

The 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 nervous signals in learning and memory.

Memantina belongs to the group of medications called NMDA receptor antagonists. Memantina acts on these receptors by improving the transmission of nervous signals and memory.

Do not take Memantina Stada

• if you are allergic (hypersensitive) to hydrochloride of memantine or to any of the other components of this medication(see section 6).

Warnings and precautions

• if you have recently suffered a myocardial infarction (heart attack), if you have congestive heart failure or if you have uncontrolled high blood pressure.

In the above situations, treatment must be closely monitored and your doctor must reevaluate the clinical benefit ofmemantineregularly.

If you have renal insufficiency (kidney problems), your doctor must closely monitor renal function and, if necessary, adjust the dose of memantine accordingly.

Follow exactly the administration instructions of this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Dosage

Please follow the following instructions when using the dosifier. Pictograms are attached with the necessary indications for the correct use of the dosifier.

One pulse contains 5 mg of hydrochloride memantine.

The recommended dose of memantine in adult patients and elderly patients is four pulses of the dosifier, which is equivalent to 20 mg once a day. In order to reduce the risk of adverse effects, this dose is achieved gradually following the daily treatment schedule:

The starting dose is one pulse once a day (5 mg) in the first week. This dose is increased in the second week to two pulses once a day (10 mg) and in the third week to three pulses once a day (15 mg). From the fourth week, the recommended dose is four pulses once a day (20 mg).

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.

Remove the cap from the bottle:

The cap must be turned in the opposite direction to the clock hands, 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. Insert the plastic tube carefully into the bottle. Keep the dosifier on the bottle neck and turn in the direction of the clock hands until it is firmly attached (fig.3). The dosifier should only be screwed once when starting use and should never be unscrewed.

How the dosifier works:

The dosifier head has two positions and turns easily

• in the opposite direction to the clock hands to open
• in the direction of the clock hands 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 pulse), it already dispenses the correct dose (fig.6).

Correct use of the dosifier:

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 pulse.

The dosifier should only be used with memantine 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 memantine.

Dosage for patients with renal insufficiency

If you have kidney problems, your doctor will decide on the appropriate dose for your condition. In this case, your doctor should monitor your renal function regularly.
