Aricep 5 Tablet – A trusted medication for Alzheimer's and dementia care.
Aricep 5 Tablet
Product Introduction
Aricept 5 Tablet, containing 5mg of Donepezil hydrochloride, is a medication primarily prescribed for the treatment of mild to moderate Alzheimer's disease. Developed by Eisai Co. Ltd. and marketed in collaboration with Pfizer, this medication has become a cornerstone in dementia treatment since its approval by the FDA in 1996.
Donepezil belongs to a class of drugs called cholinesterase inhibitors, which work by increasing levels of acetylcholine, a neurotransmitter vital for memory and cognitive function. By slowing the breakdown of acetylcholine in the brain, Aricept helps improve cognitive function and may temporarily slow the progression of symptoms in Alzheimer's patients.
Aricept 5 Tablet is typically the starting dose for most patients, offering a balance between therapeutic effect and minimal side effects. It comes in an easy-to-swallow tablet form and is usually taken once daily, preferably before bedtime.
While Aricept does not cure Alzheimer's disease, clinical studies have demonstrated its efficacy in improving memory, awareness, and the ability to perform daily functions. Some patients experience stabilization or temporary improvement in cognitive symptoms, enhancing quality of life and potentially delaying the need for full-time care.
Healthcare providers usually prescribe Aricept as part of a comprehensive treatment plan that may include behavioral therapy, lifestyle modifications, and caregiver support. The medication is most effective when started early in the disease course, though benefits can still be observed in patients with moderate disease.
Patients taking Aricept 5 Tablet require regular monitoring to assess effectiveness and manage potential side effects. The dosage may be increased to 10mg daily after 4-6 weeks if well-tolerated and clinically indicated. As with any prescription medication, Aricept should only be taken under medical supervision and according to the prescribed regimen.
Understanding the benefits, limitations, and proper use of Aricept 5 Tablet is essential for patients and caregivers navigating the challenges of Alzheimer's disease management.

How Aricept Tablet Works
Aricept works by inhibiting the enzyme acetylcholinesterase, which is responsible for breaking down acetylcholine. This action increases acetylcholine levels in the brain, compensating for the loss of functioning brain cells.
How the Drug Works (Mechanism of Action)
In Alzheimer's disease, there is a decrease in cholinergic neurons, resulting in reduced levels of acetylcholine, a neurotransmitter critical for learning and memory. Donepezil is a reversible inhibitor of acetylcholinesterase, the enzyme that breaks down acetylcholine. By blocking this enzyme's activity, donepezil increases both the level and duration of action of acetylcholine in the synaptic cleft, enhancing cholinergic neurotransmission and improving cognitive function.
Dosage of Aricept Tablet
Daily Dose
- Initial dose: 5mg once daily, usually taken at bedtime
- Maintenance dose: After 4-6 weeks, may be increased to 10mg once daily if needed and tolerated
- Maximum dose: Generally 10mg daily (23mg available for severe Alzheimer's)
Missed Dose
- If a dose is missed, take it as soon as remembered
- If close to the next scheduled dose, skip the missed dose
- Do not double the dose to make up for a missed one
Overdose
- Symptoms may include severe nausea, vomiting, excessive salivation, sweating, bradycardia, hypotension, respiratory depression, collapse, and seizures
- Seek immediate medical attention if overdose is suspected
Mode of Action of Aricept Tablet
Aricept works selectively in the central nervous system, with minimal peripheral activity. It has a higher affinity for acetylcholinesterase in the brain than in peripheral tissues, making it effective for treating cognitive symptoms while minimizing peripheral cholinergic side effects.
