Sangiorgi, M. Barbagallo, M. Giordano, M. Meli and R. Panzarasa The clinical efficacy and the
tolerability of alpha-glycerophosphocholine (alpha-GPC),
a drug able to provide high levels of choline for the nervous
cells of the brain and to protect their cell walls, have been
tested in a clinical open multicenter trial on 2044
patients suffering from recent stroke or transient
ischemic attacks. alpha-GPC was administered after the
attack at the daily dose of 1000 mg im for 28 days and orally at the
dose of 400 mg tid during the following 5 months after
the first phase. The evaluation of the efficacy on the
psychic recovery was done by the Mathew Scale (MS) during
the period of im drug administration, and using the Mini
Mental State Test (MMST), the Crichton Rating Scale (CRS), and the
Global Deterioration Scale (GDS) during the following
period of oral administration. The MS mean increased 15.9
points in 28 days in a statistically significant way (p <
0.001) from 58.7 to 74.6. At the end of the 5 month oral
administration, the CRS mean significantly decreased 4.3
points, from 20.2 to 15.9 (p < 0.001); the MMST mean significantly
increased (p < 0.001) from 21 to 24.3 at the end of the trial,
reaching the "normality" score at the 3rd month
assessment. The GDS score at the end of the trial
corresponded to "no cognitive decline" or "forgetfulness" in
71% of the patients. Adverse events were complained of by 44
patients (2.14%); in 14 (0.7%) the investigator preferred
to discontinue therapy. The most frequent complaints were
heartburn (0.7%), nausea-vomit (0.5%),
insomnia-excitation (0.4%), and headache (0.2%). The trial confirms
the therapeutic role of alpha-GPC on the cognitive
recovery of patients with acute stroke or TIA, and the
low percentage of adverse events confirms its excellent
tolerability.
