| pubmed-article:1866755 | pubmed:abstractText | Experimental ischemia models have shown the antitussive dextromethorphan to be an N-methyl-D-aspartate antagonist with neuroprotective properties. We treated 10 patients with a history of recent stroke or transient ischemic attack with oral dextromethorphan (60 mg q.i.d.) for 3 weeks in a placebo-controlled, double-blind, crossover tolerance study. We documented no clinical evidence of toxicity attributable to dextromethorphan in this preliminary study. | lld:pubmed |
