Memantine Ratiopharm (Memantine Hydrochloride)

Memantine works by blocking the NMDA receptor’s ion channel in a non‑competitive manner. This reduces excessive calcium influx caused by overstimulation with glutamate, limiting excitotoxic neuronal damage that contributes to the progression of Alzheimer’s disease.

The appropriate dose of Memantine Ratiopharm is determined by the prescribing healthcare professional based on the patient’s condition, renal function, and response to therapy. Dosage adjustments are made individually and should follow the prescriber’s instructions.

Memantine is classified as contraindicated in pregnancy unless the potential benefit justifies the risk to the fetus. Limited data are available for breastfeeding, and the drug may pass into breast milk, so use is generally discouraged unless essential.

To order, 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 necessary import documentation.

Memantine belongs to the NMDA antagonist class, whereas cholinesterase inhibitors (e.g., donepezil) increase acetylcholine levels. Memantine is typically used in moderate to severe stages, often in combination with a cholinesterase inhibitor, offering a complementary mechanism of action.

Memantine Ratiopharm tablets should be stored at room temperature, below 25 °C, in the original blister pack. Protect them from moisture, excessive heat, and direct sunlight to maintain product stability.

The medication is taken orally, usually once daily, with or without food as directed by the prescriber. Swallow the tablet whole with a glass of water; do not crush or chew unless specifically instructed.

Serious risks include seizures, severe skin reactions such as Stevens‑Johnson syndrome, and potential liver injury. Patients should seek immediate medical attention if they experience convulsions, rash, or signs of hepatic dysfunction.

Memantine is contraindicated in patients with known hypersensitivity to memantine or any component of the formulation. Caution is advised for individuals with severe renal impairment, uncontrolled epilepsy, or those who are pregnant or breastfeeding without a clear therapeutic need.
