Nemdatine (Memantine Hydrochloride)

Memantine works by binding to the NMDA‑type glutamate receptor as a non‑competitive antagonist. This blocks excessive calcium entry that occurs during prolonged glutamate stimulation, reducing excitotoxic neuronal damage while allowing normal synaptic activity to continue.

The dosage of Nemdatine is determined by the prescribing clinician based on the patient’s condition, renal function, and other individual factors. The prescriber will set the appropriate dose and titration schedule according to current clinical guidelines.

Safety data for memantine during pregnancy and lactation are limited. It is generally advised to avoid use unless the potential benefit to the mother clearly outweighs any possible risk to the fetus or infant.

The primary alternative class for Alzheimer’s disease is acetylcholinesterase inhibitors such as donepezil. While those agents increase acetylcholine levels, memantine targets glutamatergic excitotoxicity. Both classes may be used together, but memantine is often chosen for patients with moderate to severe disease or when cholinergic side effects are problematic.

Nemdatine should be stored at room temperature, below 25 °C, in its original packaging. Keep the product away from moisture, direct sunlight and excessive heat to maintain stability and potency.

Nemdatine is taken orally, usually once daily. It can be swallowed with or without food, but patients should follow the specific instructions provided by their healthcare professional to ensure consistent absorption.

Serious adverse reactions, although uncommon, include hallucinations, seizures and severe allergic responses such as anaphylaxis. Patients should seek immediate medical attention if they experience any of these symptoms.

Nemdatine is contraindicated in patients with known hypersensitivity to memantine or any component of the formulation. Caution is also advised for individuals with severe renal impairment, uncontrolled hypertension, or those taking other NMDA antagonists.
