Mantomed

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

Memantine is used in the management of Alzheimer’s disease, acting on the glutamatergic pathway to mitigate neurodegeneration. - Alzheimer’s disease (moderate to severe): improves cognition and functional abilities. - Alzheimer’s disease (mild to moderate) as adjunct to cholinesterase inhibitors: may provide additional benefit when combined therapy is needed. - Behavioral disturbances in Alzheimer’s disease: may reduce agitation and aggression associated with the condition.

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. - Cardiac arrhythmia: irregular heart rhythm. - Severe hypersensitivity: rash, swelling, or anaphylaxis. - Hepatic dysfunction: elevated liver enzymes or jaundice. - Stevens‑Johnson syndrome: severe skin reaction. - Suicidal ideation: thoughts of self‑harm.

Memantine should be used with caution in specific clinical situations. - Renal impairment: assess renal function and adjust therapy as needed. - Hepatic impairment: monitor liver function tests regularly. - History of seizures: observe for increased seizure activity. - Concomitant NMDA agonists: avoid combined use to prevent antagonistic effects. - Pregnancy: risk unknown; use only if potential benefit justifies potential risk. - Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Amantadine: additive NMDA antagonism may increase toxicity. - Other NMDA antagonists: combined use can lead to excessive CNS depression. - Strong CYP450 inhibitors (e.g., ketoconazole): may raise memantine plasma concentrations.

Moderate Interactions (Monitor Closely): - Anticholinergic agents: may diminish therapeutic benefit. - Diuretics: can heighten risk of dizziness or hypotension. - Alcohol: may enhance central nervous system effects and increase sedation.
