MEMEXA 10 mg (Memantine) – Medical Description

Dosage form: Film-coated tablets | Pack size: 30 tablets

Product Overview

Memexa 10 mg contains memantine, an N-methyl-D-aspartate (NMDA) receptor antagonist used to manage symptoms associated with moderate to severe dementia due to Alzheimer's disease. It works by regulating the activity of glutamate, a neurotransmitter involved in learning and memory, and may help support cognitive function and daily activities in affected patients. It does not cure Alzheimer's disease or stop its progression.

Indications and Potential Benefits

• Management of Alzheimer's disease: Helps manage symptoms of moderate to severe Alzheimer's-related dementia.
• Cognitive function: May help maintain memory, attention, and thinking abilities in some patients.
• Daily functioning: May help preserve the ability to perform everyday activities.
• Symptom management: May help stabilize or slow the worsening of symptoms for a period in some patients.

Individual responses vary, and treatment benefits should be assessed by the treating physician.

Mechanism of Action

Memantine blocks NMDA receptors in the brain in a voltage-dependent and moderate-affinity manner. This helps regulate excessive glutamate-mediated stimulation, which may contribute to neuronal dysfunction. Its action may help improve or maintain symptoms associated with Alzheimer's disease.

Dosage and Administration

• Recommended initiation: Treatment is usually started at a low dose of 5 mg once daily, followed by gradual increases of 5 mg at intervals of at least one week, as directed by the physician.
• Usual target dose: 20 mg daily, commonly administered as 10 mg twice daily.
• Administration: May be taken with or without food.
• Important: Memexa 10 mg should be taken according to the prescribed titration schedule. The appropriate dose may differ depending on kidney function and individual tolerability.

Possible Side Effects

Common or reported side effects include:

• Dizziness and headache.
• Confusion or sleepiness.
• Constipation.
• Nausea, vomiting, or diarrhea.
• Changes in behavior, including agitation in some patients.

Seek urgent medical attention if serious symptoms occur, such as difficulty breathing or hallucinations.

Warnings and Precautions

• Kidney impairment: Dose adjustment may be necessary in severe renal impairment.
• Seizure history: Inform the physician if the patient has a history of seizures.
• Urinary problems: Inform the physician about bladder conditions or difficulty urinating.
• Drug interactions: Tell the physician about all medicines and supplements being used, particularly other NMDA antagonists, dextromethorphan, and medicines that may alkalinize urine, such as sodium bicarbonate.
• Discontinuation: Do not stop treatment or restart after missing several days without consulting the prescribing physician.
