Abstract
Ischemic
stroke is amongst the top four causes of mortality and the leading
cause of disability in the world. The aim of this study was to evaluate
the efficacy of a high dose memantine on neurological function of
patients with ischemic stroke. In a randomized, 2 armed, open-label
study, patients with mild to moderate cerebral thromboembolic event
(CTEE) who admitted to Imam Hossein Hospital, Tehran, Iran, during
preceding 24 hours, entered the study. Patients allocated in two study
groups of memantine (as add-on therapy) and control. All patients were
managed based on the American Heart Association and American Stroke
Association (AHA/ASA) guidelines. Patients in memantine group received
conventional treatment plus memantine 20 mg TID. The National Institute
of Health Stroke Scale (NIHSS) was determined and recorded daily. The
primary objective was comparison of the changes in NIHSS in the study
groups at day 1 and day 5 of intervention. Significance level of
p<0.05 was considered for statistical analysis. Patients were
randomly allocated in control (15 women and 14 men, age 70.78 ± 10.92
years) and memantine (16 women and 8 men, age 73.33 ± 9.35 years)
groups. There were no significant differences in age and sex
distribution of two study groups as well as in comorbidities and
concurrent drugs. NIHSS changes were significantly different between
control (1.24 ± 0.96) and memantine group (2.96 ± 0.1), (p < 0.0001).
Our results reveal that memantine added to standard treatment of CTEE
could result in a remarkable decrease in the NIHSS confirming
improvement of the neurological function of the patients.
