Memantine Arrow Lab (Memantine Hydrochloride)

Memantine works as a non‑competitive antagonist of the NMDA receptor. By blocking the receptor‑associated ion channel, it limits excessive calcium influx caused by prolonged glutamate activity, thereby decreasing excitotoxic neuronal injury while preserving normal synaptic transmission.

The dosage of memantine is individualized by the prescribing clinician based on the patient’s clinical condition, renal function, and response to therapy. Typical regimens start with a low dose that is gradually increased, but the exact schedule must be determined by a qualified healthcare professional.

Safety data for memantine during pregnancy and lactation are limited. The drug should only be used when the potential benefit justifies any possible risk to the fetus or infant, and the decision should be made by the treating physician in consultation with the patient.

The primary alternative class for Alzheimer’s disease is cholinesterase inhibitors such as donepezil. While cholinesterase inhibitors increase acetylcholine levels, memantine modulates glutamatergic activity. Both classes can be used together; memantine is often added when patients no longer respond adequately to cholinesterase inhibition alone.

Memantine Arrow Lab should be stored at ambient temperature, preferably below 25 °C. Keep the tablets in the original container, protect them from moisture, heat and direct sunlight, and ensure the packaging remains tightly closed until use.

The product is taken orally, usually once daily, with or without food, as directed by the prescribing physician. Tablets should be swallowed whole with a glass of water and not crushed or chewed unless specifically instructed.

Serious adverse reactions include seizures, severe allergic responses such as rash or anaphylaxis, hallucinations or other psychotic symptoms, and suicidal thoughts or behavior. Patients should seek immediate medical attention if any of these events occur.

Memantine is contraindicated in patients with known hypersensitivity to memantine or any of its excipients. Caution is advised for individuals with severe renal impairment, uncontrolled epilepsy, or a history of serious psychiatric disorders, and the drug should be avoided in these situations unless a physician determines it is essential.
