Donepezil (Aricept) imported drug name and comparison of differences with domestic versions

Donepezil (Donepezil) is an acetylcholinesterase inhibitor (AChEI), mainly used to treat mild to moderate cognitive impairment in Alzheimer's disease (AD). It inhibits the decomposition of acetylcholine and increases the concentration of acetylcholine in the brain, thereby improving patients' cognitive function, memory and daily living abilities. The imported version is mainly sold under the trade name Aricept® (aripiper) in the international market, while it is usually labeled as Aricept®, most of the dosage forms are 5mg, 10mg or 23mg sustained-release tablets.

There are differences between the imported donepezil and the domestic version in production process, drug purity and sustained release technology . Imported drugs usually use advanced sustained-release technology and high-purity raw materials to ensure drug stability and bioavailability. Although the domestic version has the same active ingredients, there may be differences in sustained-release film technology, excipients, and production standards. Therefore, the absorption rate or drug effect maintenance time in individual patients may be slightly different.

Research shows that imported and domestic donepezil are generally equivalent in terms of clinical efficacy and both can improve the cognitive function, behavioral symptoms and daily living abilities of patients with mild to moderate Alzheimer's disease. Because the preparation process of imported drugs is more stable, some patients have slightly better drug stability, gastrointestinal tolerance, or long-term use experience. Domestic drugs have advantages in terms of price and accessibility, but tolerance monitoring for special groups (such as elderly patients and patients with chronic diseases) requires individualized assessment based on physician guidance.

When choosing imported or domestically produced donepezil, a comprehensive consideration should be made based on the patient's financial status, drug availability and doctor's recommendations . For patients who require higher drug tolerance or long-term maintenance treatment, the imported Aricept may be more suitable; while the domestic version has the advantage of being affordable and easy to obtain. No matter which version you choose, you should take the medication regularly under the guidance of a doctor, regularly monitor cognitive function and adverse reactions, and combine it with healthy lifestyle intervention to achieve the best therapeutic effect.
