1. WHAT MEMANTINE HYDROCHLORIDE IS AND WHAT IT IS USED FOR How does Memantine hydrochloride work
Memantine hydrochloride 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 hydrochloride belongs to a group of medicines called NMDA-receptor antagonists. Memantine hydrochloride acts on these NMDA-receptors improving the transmission of nerve signals and the memory.
What is Memantine hydrochloride used for
Memantine hydrochloride is used for the treatment of patients with moderate to severe Alzheimer’s disease.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE MEMANTINE HYDROCHLORIDE Do not take Memantine hydrochloride

Warnings and precautions
- if you have a history of epileptic seizures
- if you have recently experienced a myocardial infarction (heart attack), or if you are suffering from congestive heart failure or from an uncontrolled hypertension (high blood pressure).

If you suffer from renal impairment (kidney problems), your doctor should closely monitor your kidney function and if necessary adapt the memantine doses accordingly.
