Mantomed (Memantine Hydrochloride)

Memantine is a non‑competitive antagonist of the NMDA receptor. It blocks the receptor’s ion channel when it is excessively activated by glutamate, limiting calcium overload and neuronal injury while allowing normal synaptic activity to continue.

The dosage of Mantomed is individualized by the prescribing clinician based on the patient’s clinical status, renal function, and tolerability. The prescriber determines the appropriate starting dose and any subsequent titration.

Safety data for memantine in pregnancy and lactation are limited. It should be used only if the potential benefit justifies the potential risk to the fetus or infant, and the decision should be made in consultation with a healthcare professional.

To request Mantomed, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any required import documentation.

The primary alternative class is acetylcholinesterase inhibitors such as donepezil. While those agents increase acetylcholine levels, memantine targets glutamatergic excitotoxicity. Clinical practice often combines both mechanisms, but memantine is preferred for moderate‑to‑severe stages where NMDA‑mediated damage is more prominent.

Mantomed should be stored at ambient temperature, preferably below 25 °C, in its original packaging to protect it from moisture and light. Keep the product out of reach of children and avoid storing in humid or excessively hot environments.

Mantomed is taken orally, usually once daily after a meal to improve tolerability. The tablet should be swallowed whole with water and not crushed, chewed, or split unless specifically instructed by a healthcare provider.

Serious adverse events include seizures, severe allergic reactions such as rash or angioedema, and neuropsychiatric effects like hallucinations or psychosis. Patients should seek immediate medical attention if any of these symptoms occur.

Mantomed is contraindicated in patients with known hypersensitivity to memantine or any excipients in the formulation. Caution is advised for individuals with uncontrolled seizures, severe renal impairment, or those taking other NMDA antagonists.
