Haloperidol reportedly induces dysphagia. In the present study, we established a haloperidol-induced dysphagia model in guinea pigs, and evaluated the effects of ginger, kikyoto, and a mixture of ginger and kikyoto on swallowing. Swallowing ability was evaluated using behavioral tests, computed tomography (CT), and videofluoroscopic examination of swallowing. To investigate the effect of ginger and kikyoto on swallowing, ginger, kikyoto, or a mixture of ginger and kikyoto was administered orally to guinea pigs with haloperidol-induced dysphagia. Effects of these compounds were evaluated with behavioral tests. Chronic administration of haloperidol reduced the number of swallows, as evaluated by the behavioral test and videofluoroscopic examination of swallowing. In our model, these compounds improved swallowing dysfunction. Our results suggest that this model might be useful in revealing the pathogenesis of dysphagia and evaluating compounds that might improve swallowing.展开更多
