1. What Memigmin is and what it is used for

How Memigmin works
Memigmin belongs to a group of medicines known as antidementia agents.
Memory loss in Alzheimer's disease is caused by disturbances in the transmission of nerve impulses that carry information in the brain. In the brain, there are receptors known as N-methyl-D-aspartate (NMDA) receptors, which are involved in transmitting nerve signals important for learning and memory processes. Memigmin belongs to a group of medicines called NMDA receptor antagonists. By acting on NMDA receptors, Memigmin improves the transmission of nerve impulses and memory function.

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

2. Important information before using Memigmin

When not to use Memigmin

  • If the patient is allergic to memantine hydrochloride or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before starting treatment with Memigmin, consult a doctor or pharmacist:

  • if the patient has previously experienced epileptic seizures;
  • if the patient has recently suffered a myocardial infarction (heart attack), or suffers from congestive heart failure or uncontrolled hypertension (high blood pressure).

In the above situations, treatment with Memigmin should be carried out under strict medical supervision, with the treating physician regularly assessing the effectiveness of the ongoing therapy.

If the patient has impaired kidney function (kidney problems), the treating physician should closely monitor kidney function and, if necessary, adjust the memantine dosage accordingly.

Concomitant use of the following drugs should be avoided: amantadine (used to treat Parkinson's disease), ketamine (a substance usually used as an anaesthetic), dextromethorphan (commonly used to treat cough), and other medicines belonging to the group of NMDA antagonists.

The treating physician should be informed if the patient has recently changed or plans to substantially change their diet (e.g. switching from a normal diet to a strict vegetarian diet), or if the patient has been diagnosed with renal tubular acidosis (RTA, excessive concentration of acidic substances in the blood caused by impaired kidney function) or severe urinary tract infections. In such cases, the treating physician may need to modify the dosage of the medicine.
