Memantine is an NMDA‑receptor antagonist used in the management of Alzheimer’s disease, a neurodegenerative disorder affecting cognition and function. - Moderate to severe Alzheimer’s disease: improves cognition, daily functioning and may slow functional decline. - Alzheimer’s‑related behavioral symptoms: may reduce agitation and aggression in some patients. - Cognitive impairment due to Alzheimer’s: helps maintain memory and orientation abilities.

Memantine is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Dizziness: sensation of light‑headedness or unsteadiness. - Headache: mild to moderate pain in the head region. - Constipation: reduced bowel movements or hard stools. - Fatigue: feeling unusually tired or low in energy. - Nausea: upset stomach or urge to vomit.

Serious or Rare Side Effects: - Seizures: convulsive episodes requiring immediate medical attention. - Severe allergic reaction: rash, swelling, breathing difficulty. - Hallucinations or psychosis: visual or auditory disturbances. - Cardiac arrhythmia: irregular heart rhythm. - Suicidal thoughts: emergence of depressive or suicidal ideation.

Before initiating Memantine, clinicians should consider several safety factors. - Renal impairment: assess kidney function and adjust dose if needed. - Hepatic impairment: monitor liver enzymes and consider dose modification. - History of seizures: use with caution and monitor for new seizure activity. - Concomitant NMDA antagonists: avoid combined use to reduce neurotoxicity risk. - Pregnancy and lactation: safety not established; weigh potential benefits against risks. - Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Memantine may interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Amantadine or other NMDA antagonists: increased risk of neurotoxic effects. - Strong CYP450 inhibitors (e.g., ketoconazole): may raise plasma levels, though metabolism is limited.

Moderate Interactions (Monitor Closely): - NSAIDs: may increase risk of edema or hypertension. - Diuretics: enhanced dizziness or hypotension. - Antihypertensives: possible additive blood pressure lowering. - Anticholinergic agents: may worsen cognitive impairment.
