Memantine is a medication designed to help improve memory, awareness, and the ability to perform daily functions in patients with Alzheimer's disease. It works by blocking excess activity of a chemical called glutamate, which may reduce nerve cell damage. This ingredient is found in many trusted generic options for dementia care. Our platform offers reliable access to medications containing Memantine, supporting patients and caregivers with secure access to quality treatments.
Memantine is a medication that belongs to a group of drugs called NMDA-receptor antagonists. It is used to help manage symptoms of certain brain conditions by protecting nerve cells from excessive activity. In the UK, mem-antine can be found in medicines such as Namenda, Memantine, and Namzaric.
A few different products contain memantine as their active ingredient:
These medicines are offered in oral tablet form, and the strengths range from low-dose tablets (5 mg) up to higher-dose tablets (20 mg). While Namenda and the generic memantine are used on their own, Namzaric provides a convenient single tablet for people who need both active ingredients.

Memantine works by gently blocking the activity of a chemical called glutamate at a specific site called the NMDA receptor. In Alzheimer’s disease, glutamate can become over-active and damage brain cells. By moderating this activity, memantine helps protect neurons and may lessen the speed of symptom progression. The effect is modest, and improvements are usually seen over weeks rather than instantly.

Store memantine tablets in a dry place, away from direct sunlight and at room temperature. Keep them out of reach of children. Treatment duration varies; some people use the medicine for a few months, while others may continue for many years, depending on disease progression and the advice of their NHS clinician. Always follow the instructions that come with the specific product you have been prescribed, as dosing and monitoring can differ between Namenda, generic memantine, and Namzaric.
