1. What is Memolek and what is it used for
Memolek contains the active substance memantine hydrochloride. Memolek belongs to a group of medicines called anti-dementia medicines.
Memory loss in Alzheimer's disease is due to disturbances in the transmission of nerve impulses in the brain. In the brain, there are so-called N-methyl-D-aspartate (NMDA) receptors that are involved in the transmission of nerve signals important for learning and memory processes.
Memolek belongs to a group of medicines called NMDA receptor antagonists. Memolek, by acting on NMDA receptors, improves the transmission of nerve impulses and memory.
Memolek is used to treat patients with moderate to severe Alzheimer's disease.
2. Important information before taking Memolek
When not to take Memolek
- if you are allergic to memantine or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Before starting treatment with Memolek, discuss with your doctor or pharmacist:
- if you have had seizures in the past;
- if you have recently had a heart attack (myocardial infarction) or suffer from congestive heart failure or uncontrolled high blood pressure.
In these situations, treatment with Memolek should be carried out under close medical supervision, and the doctor should regularly assess the effects of the treatment.
When administering memantine to patients with renal impairment (kidney problems), the doctor should closely monitor kidney function and, if necessary, adjust the dosage of the medicine.
If the patient has been diagnosed with renal tubular acidosis (RTA, excessive concentration of acidic substances in the blood due to kidney dysfunction) or severe urinary tract infections (structures through which urine flows), the doctor may need to modify the dosage of the medicine.
Concomitant use of such medicines as amantadine (used in Parkinson's disease), ketamine (used for anesthesia), dextromethorphan (used to treat cough), and other NMDA receptor antagonists should be avoided.
Children and adolescents
Memolek is not recommended for children and adolescents under 18 years of age.
