Galantamine
SaveAn acetylcholinesterase inhibitor and allosteric nicotinic receptor modulator FDA-approved for mild-to-moderate Alzheimer's disease. Originally derived from snowdrop flowers.
Quick verdict
Dual mechanism (AChE inhibition + nicotinic modulation) distinguishes it from donepezil. Similar modest efficacy for Alzheimer's symptoms. Also used off-label for lucid dreaming.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Multiple large RCTs show significant improvement in cognition (ADAS-cog) and global function in mild-to-moderate AD. Dual mechanism may provide theoretical advantages but head-to-head superiority over donepezil is not established. Notable off-label popularity for enhancing lucid dreaming due to REM sleep modulation.
Benefits
- Dual AChE inhibition and nicotinic receptor modulation
- FDA-approved for mild-to-moderate Alzheimer's
- Well-established efficacy from large clinical programs
Dosage notes
Start 4 mg twice daily with meals. Increase to 8 mg twice daily after 4 weeks, then 12 mg twice daily. Extended-release: 8–24 mg once daily.
Side effects
- Nausea
- Vomiting
- Diarrhea
- Decreased appetite
- Dizziness
Who should be cautious
Same cholinergic cautions as donepezil: bradycardia, GI effects, worsening of asthma/COPD. Hepatic impairment requires dose adjustment.
What this page cannot tell you
Symptomatic treatment only. No head-to-head superiority over other AChE inhibitors demonstrated.
