Citicoline (CDP-Choline) for Cerebral Infarction Volume
Citicoline was studied extensively for acute ischemic stroke based on membrane-stabilizing mechanisms. The large ICTUS trial found no significant benefit on recovery. It remains reasonable for cognitive applications, but not for reducing infarct volume — emergency reperfusion therapy is what saves brain tissue.
Overview
Verdict
Citicoline showed neuroprotection promise, but a large trial found no benefit for limiting stroke damage.
How It Works
Dosing & Protocol
Typical dose
- Recommended dose
- Not recommended for stroke. Standard cognitive dosing (250–500 mg/day) has no established role in infarct volume.
- Expected timeframe
- Not applicable.
Protocol
- studied dose
- Acute stroke trials used 500-2000 mg/day started within 24 hours of onset, by intravenous or oral route
- evidence note
- Verdict is insufficient - the large trials were negative and this is a hospital question, not a supplement one
- what happened
- Early studies suggested reduced infarct growth, but the pooled ICTUS trial and subsequent meta-analyses found no significant benefit on functional outcome or infarct volume. Standard cognitive dosing of 250-500 mg/day has no established role in infarct volume at all
- what to do instead
- Acute stroke care is time-critical: call emergency services immediately for sudden face, arm or speech symptoms. Thrombolysis and thrombectomy within the treatment window are what reduce infarct volume
- secondary prevention
- Blood pressure control, antiplatelet or anticoagulant therapy as prescribed, statins, smoking cessation
Evidence
Citicoline in acute ischemic stroke: A randomized controlled trial
et al
We did not find any significant difference between the Citicoline or placebo arms with respect to either our primary or secondary outcomes.
Safety
Caveats
Do not use in place of emergency stroke care. Act FAST on stroke symptoms — time to thrombolysis/thrombectomy determines outcome.
