ADMENTA 10MG

# MEMANTINE 10 MG ## SHORT DESCRIPTION **Memantine 10 mg** is a prescription medicine used primarily to help manage symptoms of **moderate to severe Alzheimer's disease**. It belongs to a group of medicines called **NMDA receptor antagonists**. Memantine may help improve or maintain cognitive function, daily activities, and behavioral symptoms in some people with Alzheimer's disease. It does **not cure Alzheimer's disease or stop the underlying progression of dementia**. --- ## KEY BENEFITS * Used for **moderate to severe Alzheimer's disease**. * May help support memory and thinking abilities. * May help maintain the ability to perform everyday activities. * Can help with some behavioral symptoms associated with dementia. * May be used alone or alongside certain other Alzheimer's medicines when prescribed. * Works through a different mechanism from acetylcholinesterase inhibitors. --- ## USES / INDICATIONS Memantine 10 mg may be prescribed for: * **Moderate Alzheimer's disease** * **Severe Alzheimer's disease** * Management of cognitive symptoms associated with Alzheimer's dementia Memantine may sometimes be continued alongside medicines such as donepezil, rivastigmine, or galantamine when considered appropriate by a healthcare professional. > **Memantine is not approved or appropriate for every type of dementia.** The underlying cause of cognitive impairment should be assessed by a healthcare professional. --- ## HOW IT WORKS Memantine is an **NMDA (N-methyl-D-aspartate) receptor antagonist**. Glutamate is an important neurotransmitter involved in learning and memory. Excessive glutamate activity can lead to excessive stimulation of NMDA receptors and potentially contribute to neuronal damage. Memantine blocks NMDA receptor activity in a **voltage-dependent and moderate manner**, helping reduce harmful excessive glutamate activity while allowing normal neurotransmission to continue. **Memantine → modulates excessive NMDA receptor activity → reduces pathological glutamate effects → may help preserve cognitive and functional abilities.** --- ## DOSAGE & ADMINISTRATION > **Take Memantine 10 mg exactly as prescribed by your doctor.** ### Usual Adult Dosing Memantine treatment is generally **started at a lower dose and gradually increased** to reduce the likelihood of side effects. A commonly used regimen with immediate-release tablets is: * **Week 1:** 5 mg once daily * **Week 2:** 5 mg twice daily * **Week 3:** 5 mg in the morning and 10 mg in the evening * **Week 4 onward:** 10 mg twice daily, if tolerated The usual maximum for immediate-release memantine is **20 mg per day**. For patients with significant kidney impairment, a lower maximum dose may be required. > The exact titration schedule depends on the formulation and your doctor's instructions. **Do not start directly with 10 mg twice daily unless specifically prescribed.** ### How to Take * Take with or without food. * Swallow the tablet with water. * Take doses at approximately the same time each day. * Do not crush or split tablets unless the product instructions permit it. ### Missed Dose Take the missed dose when remembered unless it is close to the next scheduled dose. **Do not take two doses at once.** If memantine treatment has been interrupted for several days, contact your doctor before restarting because the dose may need to be gradually increased again. --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Dizziness * Headache * Constipation * Sleepiness * Confusion * Fatigue * Increased blood pressure * Shortness of breath in some patients These effects may be more noticeable when treatment is first started or when the dose is increased. ### Less Common Effects Some patients may experience: * Hallucinations * Vomiting * Balance problems * Abnormal gait * Muscle-related symptoms * Increased tiredness ### Serious Side Effects Seek medical attention for severe or unusual: * Confusion * Hallucinations * Severe dizziness or falls * Seizures * Severe allergic reactions * Significant changes in consciousness or behavior --- ## PRECAUTIONS & WARNINGS ### Kidney Disease Memantine is eliminated primarily through the kidneys. Patients with **severe renal impairment** may require a lower dose or slower dose adjustment. Tell your doctor if you have kidney disease. ### Seizure Disorders Memantine should be used cautiously in people with a history of seizures or conditions that increase seizure risk. ### Heart Conditions Tell your doctor if you have significant heart disease, particularly if you experience dizziness, fainting, or abnormal heart rhythms. ### Urinary Conditions Conditions that significantly increase urine alkalinity can reduce memantine elimination and potentially increase its blood concentration. ### Dementia and Falls Dizziness, confusion, and balance problems may increase the risk of falls, particularly in older adults. Caregivers should monitor patients for changes in mobility or behavior. ### Pregnancy There is limited information regarding memantine use during pregnancy. Tell your doctor if you are pregnant, planning pregnancy, or could become pregnant. ### Breastfeeding It is not well established whether memantine passes into human breast milk. Discuss the potential risks and benefits with your healthcare professional. --- ## DRUG INTERACTIONS Tell your doctor or pharmacist about all prescription medicines, OTC medicines, supplements, and herbal products you use. ### Amantadine Memantine and **amantadine** both affect NMDA receptor activity. Combining them may increase the risk of adverse effects and should generally be avoided unless specifically directed by a healthcare professional. ### Ketamine Ketamine also affects NMDA receptors. Concurrent use may increase the risk of central nervous system adverse effects. ### Dextromethorphan Dextromethorphan has NMDA receptor activity. Combining it with memantine may increase the likelihood of adverse effects. ### Urine-Alkalinizing Medicines Medicines or conditions that significantly alkalinize urine can decrease memantine elimination and increase its blood concentration. Examples may include certain carbonic anhydrase inhibitors or large amounts of alkaline agents. ### Other Dementia Medicines Memantine may be prescribed with acetylcholinesterase inhibitors such as: * Donepezil * Rivastigmine * Galantamine Combination treatment should be supervised by a healthcare professional. ### Diuretics and Other Medicines Always provide your healthcare professional with a complete medication list, particularly if you take medicines that affect kidney function or urine pH. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep at room temperature unless otherwise specified. * Protect from excessive heat, moisture, and direct sunlight. * Keep tablets in their original packaging. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets from damaged or tampered packaging. --- ## PRESCRIPTION STATUS **Prescription Medicine** Memantine 10 mg should be used under the supervision of a qualified healthcare professional.
