1. Contents of the pack and additional information

How Memantina SUN works

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

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

What Memantina SUN is used for

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

Do not take Memantina SUN:

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

Warnings and precautions

Consult your doctor or pharmacist before starting to take Memantina SUN:

• if you have a history of epileptic seizures
• if you have recently had 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 should regularly reevaluate the clinical benefit of Memantina SUN.

If you have kidney problems, your doctor should closely monitor your renal function and, if necessary, adjust the memantine dose.

Memantine should be avoided when used with other medications such as:

• amantadine (for the treatment of Parkinson's disease),
• ketamine (a medication generally used as an anesthetic),
• dextromethorphan (a medication for the treatment of cough), and
• other NMDA antagonists.
