Memantin Heumann (Memantine Hydrochloride)

Memantine hydrochloride is a non‑competitive antagonist of the NMDA receptor. By blocking excessive activation of this receptor, it reduces calcium influx into neurons, limiting excitotoxic damage and supporting neuronal health in Alzheimer’s disease.

The dosage of Memantin Heumann is determined by the prescribing clinician based on the patient’s clinical condition, renal function, and tolerability. The prescriber will set the appropriate dose and titration schedule.

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

To order Memantin Heumann, 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 necessary import documentation.

Memantin Heumann belongs to the NMDA receptor antagonist class, which differs from acetylcholinesterase inhibitors such as donepezil. While both classes aim to improve cognition, memantine targets glutamate‑mediated excitotoxicity, offering an alternative mechanism for patients who may not respond adequately to cholinergic agents.

Memantin Heumann should be stored at room temperature, below 25 °C. Keep the product in its original packaging, protect it from moisture and direct sunlight, and ensure the container is tightly closed to maintain stability.

Memantin Heumann is taken orally, usually as a tablet. The patient should swallow the tablet whole with water and follow the prescriber’s instructions regarding timing and any dose adjustments.

Serious risks include the potential for seizures, severe allergic reactions, hallucinations, cardiac arrhythmias, and hepatic dysfunction. Patients should be monitored for these events, and any concerning symptoms should be reported to a healthcare professional promptly.

Memantin Heumann is contraindicated in patients with known hypersensitivity to memantine or any of the tablet’s excipients. Caution is advised for individuals with severe renal impairment, uncontrolled epilepsy, or those taking other NMDA antagonists.
