Combination Drug Treatment Reduces Agitation in Patients with Alzheimer's Disease
Researchers from the Cleveland Clinic recruited 220 patients with Alzheimer's dementia and agitation. During a preliminary 10 week trial, participants were randomly assigned to receive either the dextromethorphan- quinidine combination or a placebo.
Results showed that patients receiving the combination medication demonstrated fewer episodes of agitation compared to patients who received the placebo. When agitation did occur, it tended to be less severe. Researchers also found that not only is the combined drug effective, but safe.
