1. What is Protalón and what is it used for
Protalón contains the active substance memantine hydrochloride. It belongs to a group of medications known as anti-dementia medications.
Memory loss in Alzheimer's disease is due to an alteration in brain signals. The brain contains so-called N-methyl-D-aspartate (NMDA) receptors that participate in the transmission of important nerve signals in learning and memory.
Memantine belongs to the group of medications called NMDA receptor antagonists. Memantine acts on these receptors, improving the transmission of nerve signals and memory.
Protalón is used in the treatment of patients with moderate to severe Alzheimer's disease.
2. What you need to know before taking Protalón
Do not take Protalón
- if you are allergic to memantine 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 Protalón:
- if you have a history of epileptic seizures (convulsions)
- if you have recently suffered a myocardial infarction (heart attack), if you suffer from congestive heart failure, or if you have uncontrolled hypertension (high blood pressure).
In these situations, treatment should be carefully supervised, and your doctor should regularly reassess the clinical benefit of memantine.
If you have kidney problems, your doctor should closely monitor your kidney function and, if necessary, adjust the dose of memantine.
If you have renal tubular acidosis (RTA, excess of acid-producing substances in the blood due to kidney dysfunction) or severe urinary tract infections, your doctor may need to adjust the dose of the medication.
The use of memantine 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 should be avoided.

The use of Protalón is not recommended in children and adolescents under 18 years of age.
