- Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) increase acetylcholine levels by inhibiting the enzyme acetylcholinesterase which breaks down acetylcholine, leading to improved cognitive function, memory, and daily living activities
- NMDA receptor antagonist memantine blocks excessive glutamate activity at NMDA receptors, preventing overstimulation and cell damage, slowing cognitive decline in moderate to severe Alzheimer's disease
- These medications target specific neurotransmitters involved in memory and cognition
Pathophysiology and Drug Targets
- Alzheimer's disease is characterized by the accumulation of amyloid plaques and tau proteins in the brain
- These abnormal protein deposits contribute to neurodegeneration, leading to cognitive decline and memory loss
- Alzheimer's drugs aim to slow the progression of symptoms by addressing neurotransmitter imbalances and promoting neuroplasticity
Indications and effects of Alzheimer's medications
- Indications
- Mild to moderate Alzheimer's disease treated with cholinesterase inhibitors (donepezil, rivastigmine, galantamine)
- Moderate to severe Alzheimer's disease managed with memantine or a combination of memantine and cholinesterase inhibitors
- Side effects
- Cholinesterase inhibitors cause gastrointestinal issues (nausea, vomiting, diarrhea, anorexia), cardiovascular problems (bradycardia, syncope), and central nervous system effects (dizziness, headache, insomnia)
- Memantine leads to dizziness, confusion, headache, constipation, and
- Drug interactions
- Cholinesterase inhibitors interact with anticholinergics, reducing their effectiveness, and beta-blockers, increasing the risk of bradycardia
- Memantine interacts with drugs that alkalinize urine, increasing its elimination, and carbonic anhydrase inhibitors, reducing its elimination
Nursing considerations for Alzheimer's drugs
- Assess cognitive function, behavior, and daily living activities before and during treatment to monitor drug effectiveness and adjust dosage as needed
- Monitor for side effects, especially gastrointestinal (nausea, vomiting) and cardiovascular (bradycardia) issues
- Administer cholinesterase inhibitors with food to minimize gastrointestinal side effects and improve patient comfort
- Titrate doses gradually to minimize side effects and achieve optimal therapeutic response without overwhelming the patient
- Monitor renal function in patients taking memantine as it is primarily eliminated through the kidneys
- Be aware of potential drug interactions (anticholinergics, beta-blockers) and adjust medications accordingly to prevent adverse reactions
- Consider the blood-brain barrier when evaluating drug effectiveness and potential side effects
Patient education for Alzheimer's medications
- Emphasize the importance of regular medication administration (same time each day) for optimal effectiveness in managing symptoms
- Instruct on proper administration techniques, such as taking with food or titrating doses, to minimize side effects and improve adherence
- Discuss common side effects (nausea, dizziness) and when to contact the healthcare provider for severe or persistent symptoms
- Encourage maintaining a consistent daily routine and engaging in cognitive stimulation activities (puzzles, reading) to support treatment
- Stress the importance of regular follow-up appointments to monitor treatment response and adjust medications as needed based on disease progression
- Provide resources for caregiver support and education on Alzheimer's disease management, including support groups and educational materials
