Memantin Puren (Memantine Hydrochloride)

Memantine acts as a non‑competitive antagonist at the NMDA receptor. By binding to a site separate from glutamate, it blocks excessive calcium entry that occurs during pathological over‑activation, thereby reducing excitotoxic neuronal damage while preserving normal synaptic activity. This mechanism helps slow the neurodegenerative processes that contribute to cognitive decline in Alzheimer’s disease.

The dosing regimen for memantine is individualized by the prescribing clinician based on the patient’s clinical condition, renal function and tolerability. Typically, treatment starts with a low dose that is gradually increased to the target maintenance dose, but the exact schedule must be determined by a qualified healthcare provider.

The safety of memantine during pregnancy and lactation has not been established; it is classified as having an unknown pregnancy category. Consequently, it should only be used when the potential benefit to the mother outweighs any possible risk to the fetus or infant, and under close medical supervision.

Memantine belongs to the NMDA receptor antagonist class, whereas other approved agents such as donepezil, rivastigmine and galantamine are acetylcholinesterase inhibitors. Memantine is typically used for moderate to severe disease and may be combined with an acetylcholinesterase inhibitor for additive benefit, while the latter are often prescribed in mild to moderate stages.

Memantin Puren should be stored at ambient temperature, preferably below 25 °C. Keep the product in its original container, protect it from moisture and direct sunlight, and ensure the packaging remains sealed until use. Do not refrigerate or freeze the tablets.

The medication is taken orally, usually with or without food, as directed by the prescribing clinician. Tablets should be swallowed whole with a glass of water and not crushed or chewed unless specifically instructed. Adherence to the prescribed schedule is important for optimal therapeutic effect.

Although generally well tolerated, memantine can cause serious adverse events such as severe skin reactions (e.g., Stevens‑Johnson syndrome), seizures, cardiac arrhythmias, hepatic dysfunction, hallucinations, and suicidal thoughts. Patients should be monitored for these rare but potentially life‑threatening conditions and seek immediate medical attention if they occur.

Memantin Puren is contraindicated in patients with known hypersensitivity to memantine hydrochloride or any excipients in the formulation. Caution is also advised for individuals with severe renal impairment, uncontrolled epilepsy, or those taking other NMDA antagonists. Pregnant or nursing women should only use it when clearly indicated by a physician.
