METHODS: Patients with no signs of pneumonia within 7 days of stroke onset and 48 hours of insertion of a nasogastric tube were recruited into a double-blind randomized placebo-controlled trial. Participants received metoclopramide 10 mg or placebo 3x daily via the nasogastric tube for 21 days or until nasogastric feeds were discontinued. Clinical signs of pneumonia were recorded daily. Pneumonia was diagnosed if the patient had relevant clinical signs, high inflammatory markers, and new infiltrates on the chest radiograph.

RESULTS: Sixty patients (mean age, 78 years; 38 women; mean National Institutes for Health Stroke Scale score, 19.25) were randomized in a 1:1 ratio. There were significantly more episodes of pneumonia in the placebo group than in the metoclopramide group (rate ratio, 5.24; P<0.001). There were also significant differences in favor of metoclopramide in the rate of aspiration, oxygen saturation, highest inflammatory markers, and National Institutes for Health Stroke Scale. There was no significant difference in mortality between the groups.

CONCLUSIONS: This study suggests that metoclopramide may reduce the rate of pneumonia and may improve other clinical outcomes in patients with subacute stroke fed via nasogastric tube. These findings need to be confirmed in larger randomized and blinded trials.
