- Increased focus
How it works
Inhibits acetylcholinesterase, increasing acetylcholine availability in the brain.
Overview
Galantamine is used clinically in the treatment of cognitive decline, particularly in Alzheimer’s disease. Its mechanism of action makes it a potent enhancer of memory and learning. Due to its strength, it should be used with caution and typically under guidance. It is not generally considered a beginner nootropic but can be highly effective in targeted applications.
The evidence
Galantamine is a prescription cholinesterase inhibitor (and nicotinic modulator) licensed for Alzheimer's disease. Cochrane and comparative meta-analyses show a modest benefit on cognition and daily function in dementia, similar to other drugs of its class. It is popular in some circles for lucid dreaming, but there is no good evidence it enhances cognition in healthy people.
Safety & side effects
Cholinergic effects dominate: nausea, vomiting, diarrhoea, a slowed heart rate, and disturbed sleep, particularly when starting or increasing the dose.
Who should avoid it
Prescription-only — not for self-dosing. It is risky with heart-rhythm problems, asthma or COPD, and active peptic ulcers, and should not be combined with other cholinergic or anticholinergic drugs without medical advice. Use only under a prescriber.
