Citicoline is an essential precursor in the synthesis of phosphatidylcholine, a key cell membrane phospholipid, and is known to have neuroprotective effects in acute ischemic stroke. The aim of this study was to determine the efficacy and safety of oral citicoline in Korean patients with acute ischemic stroke. A drug surveillance study was carried out in 4,191 patients with a diagnosis of acute ischemic stroke. Oral citicoline (500-4000 mg/day) was administered within less than 24 h after acute ischemic stroke in 3,736 patients (early group) and later than 24 h after acute ischemic stroke in 455 patients (late group) for at least 6 weeks. For efficacy assessment, primary outcomes were patients' scores obtained with a short form of the National Institutes of Health Stroke Scale (s-NIHSS), a short form of the Barthel Index of activities of daily living (s-BI) and a modified Rankin Scale (mRS) at enrollment, after 6 weeks and at the end of therapy for those patients with extended treatment. All adverse reactions were monitored during the study period for safety assessment. All measured outcomes, including s-NIHSS, s-BI and mRS, were improved after 6 weeks of therapy (P < 0.05). Further improvement was observed in 125 patients who continued citicoline therapy for more than 12 weeks when compared with those who ended therapy at week 6. Improvements were more significant in the higher dose group (≥2000 mg/day) (P < 0.001). s-BI scores showed no differences between the early and late groups at the end of therapy. Citicoline safety was excellent; 37 side effects were observed in 31 patients (0.73%). The most frequent findings were nervous system-related symptoms (8 of 37, 21.62%), followed by gastrointestinal symptoms (5 of 37, 13.5%). Oral citicoline improved neurological, functional and global outcomes in patients with acute ischemic stroke without significant safety concerns.
