Alzheimers

What Are Alzheimers?

Alzheimer’s disease is the most common form of dementia, affecting over 55 million people worldwide. While no cure currently exists, approved pharmacological treatments can slow cognitive decline, improve daily functioning, and help manage behavioural symptoms. AmozonPill stocks 19 generic Alzheimer’s medications — all cholinesterase inhibitors and NMDA receptor antagonists used in evidence-based dementia care — at up to 95% below brand-name prices. 

Drug Classes Available

  • Cholinesterase Inhibitors: Donepezil, Rivastigmine, Galantamine — enhance cholinergic transmission by inhibiting acetylcholinesterase. Indicated for mild to moderate Alzheimer’s; Rivastigmine also available as a transdermal patch. 
  • NMDA Receptor Antagonists: Memantine — blocks excess glutamate activity, protecting neurons from excitotoxic damage. Indicated for moderate to severe Alzheimer’s; often combined with a cholinesterase inhibitor. 
  • Combination Therapy: Donepezil + Memantine combination — evidence shows greater cognitive and functional benefit in moderate to severe Alzheimer’s than either agent alone.

How to Choose the Right Product

For mild to moderate Alzheimer’s: Donepezil 5–10 mg once daily is the most widely prescribed cholinesterase inhibitor. For patients who cannot tolerate oral Donepezil: Rivastigmine transdermal patch offers equivalent efficacy with better GI tolerability. For moderate to severe Alzheimer’s: add Memantine 20 mg daily. All Alzheimer’s pharmacotherapy should be initiated and monitored by a neurologist or geriatrician. 

Frequently Asked Questions

Do Alzheimer’s medications stop the disease from progressing?

No currently approved medication stops or reverses Alzheimer’s disease progression. Cholinesterase inhibitors and Memantine slow the rate of cognitive decline and improve quality of life but do not modify the underlying disease. 

How quickly does Donepezil work?

Cognitive benefits from Donepezil typically become apparent within 4–6 weeks of starting treatment at the full dose (10 mg). Benefits are most noticeable in attention, memory, and daily activities. 

What is the difference between Donepezil and Rivastigmine?

Both are cholinesterase inhibitors with similar efficacy. Rivastigmine inhibits both acetylcholinesterase and butyrylcholinesterase (which increases as the disease progresses) and is available as a transdermal patch for patients with swallowing difficulties. 

Can Memantine be used alone without a cholinesterase inhibitor?

Yes. Memantine is approved as monotherapy for moderate to severe Alzheimer’s. However, combination therapy with Donepezil provides additional benefit in this disease stage. 

Are there side effects specific to Alzheimer’s medicines?

Cholinesterase inhibitors commonly cause GI side effects (nausea, vomiting, diarrhoea), particularly during dose escalation. These often improve with food or by switching to the patch formulation. Memantine is generally well-tolerated. 

When should Alzheimer’s medication be started?

Treatment is most beneficial when started early, in the mild to moderate stage. There is no evidence of benefit from starting treatment in the preclinical (pre-symptom) phase.
