Memantine Teva

Memantine Hydrochloride, the active ingredient in Memantine Teva, is a NMDA receptor antagonist presented as an oral formulation for oral use. It is indicated for the treatment of moderate to severe Alzheimer’s disease in adults. GNH USA supplies Memantine Teva as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Memantine Teva is an NMDA‑receptor antagonist used in the management of dementia‑related conditions. - Alzheimer’s disease (moderate to severe): improves cognition, functional abilities and global clinical status. - Dementia associated with Parkinson’s disease: may help maintain cognitive function. - Vascular dementia: may provide modest benefit in attention and memory tasks.

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

Common Side Effects: - Dizziness: sensation of light‑headedness or unsteadiness. - Headache: mild to moderate intensity. - Constipation: reduced bowel movements. - Confusion: transient disorientation. - Fatigue: feeling unusually tired. - Insomnia: difficulty falling or staying asleep.

Serious or Rare Side Effects: - Seizures: convulsive episodes requiring medical attention. - Allergic reactions: rash, pruritus, or angioedema. - Hepatic dysfunction: elevated liver enzymes. - Cardiac arrhythmias: irregular heart rhythms. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Memantine should be used with attention to patient‑specific factors. - Renal impairment: dose adjustment may be required in reduced kidney function. - History of seizures: monitor closely for increased seizure activity. - Concomitant NMDA antagonists: avoid combined use to reduce neurotoxicity risk. - Elderly patients: may be more sensitive to dizziness and confusion. - Pregnancy and lactation: safety not established; use only if clearly needed. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Memantine may interact with several medicines; awareness helps prevent adverse outcomes.

Major Interactions (Avoid): - Amantadine: additive NMDA antagonism can increase central nervous system side effects. - High‑dose memantine with other NMDA antagonists: risk of neurotoxicity. - Strong CYP450 inhibitors (e.g., ketoconazole): may raise memantine plasma levels.

Moderate Interactions (Monitor Closely): - Anticholinergic agents: may diminish cognitive benefits of memantine. - Diuretics: can affect renal clearance of memantine. - NSAIDs: may increase risk of renal impairment when combined with memantine.
