Memantina Teva-Ratiopharm

Memantine, the active ingredient in Memantina Teva-Ratiopharm, is a NMDA receptor antagonist presented as a tablet for oral use. It treats Alzheimer’s disease in adults with mild to moderate cognitive impairment.

GNH USA supplies Memantina Teva-Ratiopharm as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Memantine is used in the management of neurodegenerative conditions, primarily targeting cognitive decline associated with Alzheimer’s disease.

- Alzheimer’s disease (mild to moderate): helps improve cognition and daily functioning. - Alzheimer’s disease (moderate to severe): supports modest benefits in memory and behavior. - Dementia‑related cognitive impairment: may aid in slowing functional decline.

Common Side Effects: - Dizziness: transient light‑headedness reported by some patients. - Headache: mild to moderate intensity. - Constipation: reduced bowel movements. - Fatigue: feeling of tiredness. - Nausea: occasional upset stomach. - Confusion: temporary mental clouding.

Serious or Rare Side Effects: - Seizures: rare but potentially severe neurological events. - Allergic reactions: rash, itching, or swelling. - Stevens‑Johnson syndrome: severe skin reaction. - Hepatic dysfunction: abnormal liver enzymes. - Cardiac arrhythmia: irregular heart rhythm. - Psychosis: emergence of hallucinations or delusions.

Memantine requires careful consideration in several clinical situations.

- Renal impairment: dose may need adjustment. - Hepatic impairment: monitor liver function. - History of seizures: use with caution. - Concomitant NMDA antagonists: avoid combined use. - Pregnancy: risk unknown, prescribe only if essential. - Store at room temperature: keep in original container, protect from moisture.

Memantine can interact with other medications, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Amantadine: additive NMDA antagonism may increase toxicity. - Ketamine: combined NMDA blockade can cause severe CNS effects. - Other NMDA antagonists: heightened risk of neuropsychiatric events.

Moderate Interactions (Monitor Closely): - CNS depressants (e.g., benzodiazepines): may enhance sedation. - Anticholinergic agents: could worsen cognitive side effects. - Diuretics: may affect electrolyte balance. - Antihypertensives: monitor blood pressure changes. - SSRIs: observe for increased serotonin syndrome risk.
