Generic Aricept Information

Introduction

Aricept, whose active ingredient is donepezil, belongs to the cholinesterase‑inhibitor group used primarily for the management of Alzheimer’s disease. In the United Kingdom the medication is licensed for the symptomatic treatment of mild, moderate and severe Alzheimer’s disease, helping to maintain cognition, daily living activities and behaviour for as long as possible. The drug is manufactured by Eisai Co., Ltd. and supplied in tablet form. While Aricept is the original brand name, the same compound is available as generic donepezil, which offers a cost‑effective alternative for patients and healthcare systems.

What is Aricept?

Aricept is a tablet formulation that contains the synthetic compound donepezil hydrochloride. It is classified as a reversible acetylcholinesterase inhibitor. The product was first approved in the United States in 1996 and subsequently received European Union marketing authorisation in 1997. In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) authorises the drug for Alzheimer’s disease. Generic versions of donepezil are marketed under various brand names worldwide, including Donepezil‑Mylan, Donepezil‑Teva and locally produced equivalents. Our online pharmacy supplies the generic version of donepezil as a therapeutically equivalent, lower‑cost alternative to the branded product.

How Aricept Works

Donepezil inhibits the enzyme acetylcholinesterase, which normally breaks down the neurotransmitter acetylcholine in the synaptic cleft. By reducing enzymatic activity, donepezil increases the concentration of acetylcholine available for neurotransmission. In Alzheimer’s disease, cholinergic neurons are selectively lost; the enhanced cholinergic signalling produced by donepezil partially compensates for this deficit, leading to modest improvements in cognition, attention and the ability to perform daily tasks. The drug reaches peak plasma concentrations within 3–4 hours after oral administration, has a half‑life of roughly 70 hours, and is eliminated primarily via hepatic metabolism (CYP3A4 and CYP2D6) and renal excretion.

Conditions Treated with Aricept

• Mild to moderate Alzheimer’s disease – The primary approved indication in the UK. Clinical guidelines (NICE NG97) recommend donepezil as first‑line symptomatic therapy for patients with a confirmed diagnosis of Alzheimer’s disease.
• Severe Alzheimer’s disease – The 23 mg extended‑release formulation (not always available as a generic) is indicated for patients who have tolerated 10 mg for at least three months, providing additional symptomatic benefit.
• Off‑label uses – In some jurisdictions clinicians may consider donepezil for other dementias (e.g., Lewy body dementia or vascular dementia) when cholinergic deficits are evident, although robust evidence is limited and such use remains off‑label.

In the United Kingdom, Alzheimer’s disease affects an estimated 850,000 people, representing a growing public‑health challenge. By enhancing cholinergic transmission, Aricept can delay functional decline, reduce caregiver burden, and improve quality of life for both patients and families.

Who is Aricept For?

• Patients with a confirmed diagnosis of Alzheimer’s disease (mild, moderate, or severe) who can tolerate oral medication.
• Adults aged 18 years and older – Donepezil is approved for adult use; the majority of prescriptions involve individuals over 65, reflecting disease prevalence.
• Individuals who have not responded adequately to non‑pharmacological interventions such as cognitive stimulation, exercise, or lifestyle modification.
• Patients who have no contraindicating comorbidities (e.g., severe cardiac conduction disorders, active peptic ulcer disease, or known hypersensitivity to donepezil).

Contra‑indications include hypersensitivity to donepezil or any excipients, and concurrent use of other cholinesterase inhibitors. Caution is advised for patients with bradycardia, asthma, chronic obstructive pulmonary disease, or hepatic impairment.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting, diarrhoea
• Loss of appetite, weight loss
• Insomnia or abnormal dreams
• Muscle cramps, fatigue

Rare

• Bradycardia or sinus node dysfunction
• Exacerbation of asthma or chronic obstructive pulmonary disease (COPD)
• Elevation of liver enzymes (transaminases)
• Skin rash or pruritus

Serious

• Syncope or fainting secondary to severe bradycardia
• Gastrointestinal bleeding, especially in patients taking non‑steroidal anti‑inflammatory drugs (NSAIDs) or anticoagulants
• Seizures (rare)
• Severe hypersensitivity reactions, including Stevens‑Johnson syndrome

Clinically Relevant Drug–Drug Interactions

• Anticholinergic agents (e.g., diphenhydramine, oxybutynin) may diminish donepezil’s therapeutic effect.
• Beta‑blockers, calcium‑channel blockers, and digoxin can potentiate bradycardic effects; cardiac monitoring is advisable.
• Anticoagulants and antiplatelet drugs (warfarin, aspirin, clopidogrel) increase the risk of gastrointestinal bleeding.
• CYP3A4 or CYP2D6 inhibitors (e.g., ketoconazole, erythromycin, fluoxetine) may raise plasma levels of donepezil, potentially heightening side‑effect risk.
• Cholinergic agents (e.g., bethanechol, pilocarpine) can synergise and cause excessive cholinergic stimulation (e.g., excessive salivation, diarrhoea).

Patients should provide a full medication list, including over‑the‑counter products and herbal supplements, to their prescriber before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dose: 5 mg taken orally once daily, preferably in the evening to minimise gastrointestinal upset.
• Titration: After 4–6 weeks, the dose may be increased to 10 mg once daily if tolerated; this is the usual maintenance dose for mild‑to‑moderate disease.
• Severe disease: Some patients may be switched to a 23 mg extended‑release tablet after at least three months on 10 mg, under specialist supervision.
• Missed dose: If a dose is forgotten, take it as soon as remembered unless it is near the time of the next scheduled dose; in that case, skip the missed dose and continue with the regular schedule. Do not double‑dose.
• Overdose: Symptoms may include severe nausea, vomiting, diarrhoea, bradycardia, and muscle weakness. Immediate medical attention is required; supportive care and monitoring are the mainstays of treatment.
• Food and alcohol: Donepezil may be taken with or without food. Excessive alcohol consumption can exacerbate dizziness and should be avoided.
• Renal or hepatic impairment: No dose adjustment is required for mild‑to‑moderate impairment; severe hepatic disease warrants caution and possible dose reduction.

FAQ

• Is donepezil available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is marketed as Aricept by Eisai, while numerous generic manufacturers produce tablets containing the same active compound, donepezil. Generic versions are therapeutically equivalent and usually cost less.

• What should be done with leftover tablets if treatment is discontinued?
  Unused medication should be returned to a pharmacy for safe disposal or, if that is not possible, placed in a sealed container and disposed of in household waste. Do not flush tablets down the toilet, as environmental contamination is a concern.

• Can Aricept be stored in a refrigerator during the summer months?
  No. Donepezil tablets are stable at room temperature (15‑30 °C). Storing them in a refrigerator can cause moisture condensation, potentially degrading the tablet coating and reducing effectiveness.

• Does the tablet contain any allergens such as lactose or gluten?
  The standard donepezil tablet formulation includes lactose monohydrate and maize starch as excipients. Patients with severe lactose intolerance or celiac disease should discuss alternative formulations with their prescriber.

• Are there any special considerations for travelling with donepezil?
  When traveling abroad, keep the medication in its original packaging with a copy of the prescription or a doctor’s note, as customs may request proof of medical necessity. Also, maintain the tablets in a temperature‑controlled environment and avoid exposure to excessive heat.

• How does donepezil differ from earlier cholinesterase inhibitors like tacrine?
  Donepezil has a higher selectivity for acetylcholinesterase, a longer half‑life (≈70 h vs. 2 h for tacrine), and a markedly better safety profile, with fewer hepatotoxicity concerns that limited tacrine’s use.

• What major clinical trial led to the approval of donepezil for Alzheimer’s disease?
  The pivotal 1996 multicentre, double‑blind, placebo‑controlled trial (the “AD200” study) demonstrated statistically significant improvements in the Alzheimer’s Disease Assessment Scale‑Cognitive (ADAS‑Cog) scores after 24 weeks of 5 mg daily donepezil, supporting regulatory approval.

• Is there a difference between the 5 mg and 10 mg tablets in terms of excipients?
  Both strengths contain the same inactive ingredients; the only difference is the quantity of donepezil hydrochloride. This simplifies switching between doses without requiring a change in administration technique.

• Can donepezil affect the results of routine blood tests?
  Generally, donepezil does not interfere with standard laboratory assays. However, liver function tests should be monitored periodically because rare elevations in transaminases have been reported.

• Are there any specific UK import rules for personal use of generic donepezil ordered online?
  Personal import of medicines for a 3‑month supply is permitted under the MHRA’s “personal importation” scheme, provided the product is for personal use, comes from a licensed overseas pharmacy, and is not a controlled substance. Documentation confirming the medication’s authenticity may be requested at customs.
